- In this second video on the Yong Heng 4500psi compressor I discuss the importance of using a molecular sieve (water filter) to ensure that you are filling your tanks with DRY air. I review the GOLD Aliexpress $75 water and oil separator. A hack to convert the cotton filter to molecular sieve to better reduce water in your system.

Great video series on these compressors, mine arrives tomorrow and I've been watching these for preparation of its arrival
I am now running that same system of air oil separator and works flawlessly!
I even bought the mini jufeng air dryer to run from my air venturi compressor and it is awesome.
Here it's hydro tested every two years. That's why I'm looking at the ins and outs of a Yong Heng. What a toss up between the two fill systems! But to get away from the hand pump as I can. Thanks for your input.
Absolutely fantastic video! You are a great man for posting this very informative and thorough information!
After filling your tank, just store it overnight air valve down in a cool place so any water can condensate and accumulatie near the valve. The next day just blow out some air and any water buildup will be blown out to. Never had any corrosion in any of mine scuba tanks. No need to overengineer simple things. Just use the small filter to keep oil crud out.
There is a 3 inch nipple inside the tank so turning it upside down won't get it all out.
The oil is bypass from the piston rings. Perfectly normal hence the reason for the filter. Great vid and great advice for the safe use of these air bombs
Fantastic video, lot of good information. Thanks for taking time and posting.!
smuk386 thanks
Spot on about safety! Only problem is you have to periodically approach your system while filling to make sure you don't over pressurize your tank or exceed 4350psi of that compressor. I don't have automatic shut-off and wouldn't rely on it anyway.
I seen on Amazon where a customer said a similar version filter canister split on him while filling. SCARY indeed!
Excellent job as always! You are a tremendous asset to PCP airgunning.
Your videos have been extremely helpful! I just received my compressor yesterday. I filed it with oil today. I wanted to go through some videos just to familiarize myself with it. Thanks for all your great content!
Do what you said with the cotton filters and pack it with rice into the centre I have just got my dive bottle back from the testing factory with no issues after two and a half years of use great video 🤘
From Saudi Arabia, thank you very much, great explanation, I benefited from this wonderful video a lot
Just got your whole set up! Thanks
Thank You , excellent video !!!
Hello Air. Update on the new relay. Perfect fix.They did send the relay with all the wire attached. Makes it very simple to change. Would have been hard to figure out otherwise, They did switch and double up a couple wires. They send you one extra crimp end. I was a little unsure so I emailed and double checked with them. You will see the brown wire that burnt. You will cut that brown wire put the crimp end on there. The brown wire will now connect to a double green wire on the relay. ( Very obvious ) . I did take several pix before I did it. I will say this new relay looks ALOT better built. Hope this helps everyone. P.S. They did replace it for free. Tried to get me to pay for shipping but I was not going for any part of that after just giving them 350 and can not use my new compressor. lol they did send it for free. Thanks again for all the help Air. You were a big part of getting my wife and i to this point with tank and everything. I do have the same water and oil separator now also.
Steve Judd that is great to hear. Thank you for sharing that very important information. I still have the wrong power relay connected just because it works good enough for me. But now I feel more confident because of your update to make the switch to the correct person relay. Can you post those photos for everyone to see? Thanks
I don't see how to post them.
Great Video
Thanks
Thanks a million for this vid. I have a similar compressor and on your recommendation got the same water separator. Instead of white PVC, I used 30mm clear acrylic tube and colour changing silica gel as the desiccant. This way I can remove the desiccant canister and inspect it (goes from orange to dark green when it needs changing).
captainboing thank you! I like your idea of the color changing silica gel.
Where u get that 30mm tube at & color changing silica gel. Is the silica gel better then this guys stuff. Or the same
@@tropicthunderbolt all came from eBay. I only put an O ring around one end of the tube so the pressure can equalize on both sides. The air still has to go through it but can't explode it or crack it from the inside. The gel is orange and goes dark green when it is soaked. You can reverse it by putting it in your oven at 60C until it goes back to orange. From reading around d it seems people think the gel is as good as MLS but I am not a chemist so you have to be happy in yourself. Ill see if I can do a vid of it and post it for ya. You could try some sieve as well if you want, just a matter of changing out the cannister content but I like that I know when it needs changing... that was an accident btw. I discovered it while I was looking at dessicants

excellent video
The power relay picture is from my my own compressor. They used the pic I sent them when searching for a spare one for mine . It hasn’t failed , but smells like it’s ready to. Hopefully they send you the correct part , I’ve ordered it also . The 1st I was sent was totally the wrong part . Was great to see that you’ve done your set up exactly like mine . You do great reviews 👍
Dave Sloan thanks! Yes, the power relay I purchased from eBay for $7.57 works but the auto shutoff off does not work. Even thought the replacement relay I purchased looked the same but must be wired differently. I do love the Yong Heng compressor so far.
Dave Sloan do you have link I just got my compressor in and it ran for 10 mins and shut off smells like something burnt inside the compressor didn’t even fill my tank don’t even get to use my guns today
Look what I found on AliExpress
s.aliexpress.com/n26r6Zba
Dave Sloan I can’t believe it failed first time trying , is there a American relay or better made relay that can be used?
Big Bore Bandit I don’t know if that get you to the right spot? But if you look on AliExpress and yongheng accessories for that same picture of my part , you’ll find it . Lemme know if you find it . I ordered 2 just in case . Mine is still working . You’ll find that the adjustable pressure gauge vibration is wild . I wedged heavy foam under and beside mine and it helped a lot . His bouncing needle is what caused the shut off controller to burn out I think . I can’t get a positive off signal when it’s getting close to full.
People should hit like on his videos obviously Studied and made UPS and down in this type of field of process, I've been doing my research for maybe about 6 months and I'm still making mistakes, this is helpful Amen brother..
Thanks so much for sharing. I have just started the same journey as you but with an Aceeagle pump which is a clone of the Yong Heng...or vice versa..who knows in China right!? . I've only used mine once to top off my 4.5l tank from 160bar to a hair under 300bar. Almost the same as you i only saw a little bit of oil in the first stage and the main, bigger filter did feel dry. Hardly scientific...but also paranoid about moisture so I bought a second stage filter but it was only a small one, the same size as the inline one you get with the pump.
It's been gnawing away at me so
not content with that, I have bought exactly the same gold filter you are showing, also from Alibaba.I got it before I saw your vid...so....what can I say...great minds think alike!
Been thinking about how to hack it to get some reusable silica packs in there and the pvc pipe with the o rings is a brilliant idea.
Thanks for posting once again! Greetings from the UK!
Thanks dude
Thank you Steve 😊 I got a youg heng compressor as you have and I also bought a big water and oil fillter just yesterday because I was just using the regular little fillter that comes with it and I was using it to just to fill my guns I don't have a tank but I noticed water in my gun 🙃 so I'm going to start using that big fillter it has a big fillter with a bunch of different stuff pack together in it so you don't get water in the gun fingers crossed thanks for sharing bsafe I hde just like you lol
Hey Chris congratulations you will love the yong hang just don't overwork it keep it cool and definitely use a water separator. I want you to know that I am making a new video because I am using a new type of oil called Seco lube 500 from filtertech.com which runs a lot cleaner and does not smell. I also have a new water separator that does a better job and is readily available on Amazon or ebay.. the new water separator does not have any media inside of it rather it collects water and drops it at the bottom and is completely empty inside except for a stainless steel condenser that collects moisture and drops it at the bottom of the tube which can be bled off periodically.
Here is a link to the water separator www.amazon.com/dp/B077SX5G9V/ref=cm_sw_r_cp_apa_glt_fabc_NM2QPEVSH9E40MADTCZ9?_encoding=UTF8&psc=1

In industrial applications you dry air before compression. I’m making a pre dryer now using 3a molecular sieve and will post when I’ve proven the design. It’s a no pressure set up so inexpensive by comparison to this arrangement, though I have to say this is better than cotton! Molecular sieves are easy to monitor and recycle and cheap too.
Thanks for the info...
One more thing to consider. I think the filter should be mounted vertically. The input should be at the bottom, the output at the top. I found some 400 mesh stainless steel screen on amazon that could be used to hold in the media. 400 mesh is finer than most common bed sheets. Also there should be a check valve and a bleed valve at the bottom, to open up at the end of the run to blow out the accumulated moisture and oil (depending on how much comes out, you might want to do it every so often).I am going to use the screen at the bottom, so that it blows out good without losing any media. I'll let you know how it works. All I have right now is a 90 cu. in. bottle, but I plan to get one much larger, like 12 liter. When I do, I might add another filter in series with the other one, with it's own check and bleed valves at the input, to make sure I get most of the moisture out.With a bleed and check valve at the input of each filter, I can bleed them seperately, to see how much comes out of each filter.
I know this must seem like going overboard trying to eliminate as much moisture as I reasonably can. But like you said, the dryer the better, for the long haul. I'll try to document the process. I've ordered everything so I should be able to try it in a couple of weeks.
You wondered what the other bleed valve on the compressor was for. It's the moisture/oil bleed valve. It should be opened every so often to blow out the accumulated moisture/oil. I think you are supposed to open both of these before shutting off the compressor.
Harry
@air velocity sport - First off, thanks for the videos. Love your videos. I bought a YH compressor and haven't filled my tank yet only my pcp.****QUESTION**** So to make sure I don't break a burst disk again..... Let me list out the process and can you please confirm, I've got it down? FYI, I bought the parts to the fill assembly exactly as you have yours with the added bleed valve on the SCBA tank side. So here's what I think I understood for the Process to fill my SCBA tank from the YH: 1> Turn on YH w/ YH bleed valves open. 2> Let it
equalize to tanks residual or current pressure. 3> Now open the tank. 4> Let it fill and bleed water every five mins on the YH. 5> Auto shut off shuts down YH.. 6> Close my tank. 7>Release air from bleed valves and water on YH. 8> After Air bled from the system, safe to disconnect. Please let me know if I got it or I miss anything. Trying to not get a burst disk! =)
Dude! Thanks.
I'm going to use activated alumina without the pvc pipe since its noncorrosive. This will allow much more beads to fit. Got great deal on EBay..18.95 for 5.5#. Should last forever.
Thanks, and Respect.
I have found your videos on the compressor and the separator you did a very informative and well explained, what person did you buy the compressor from or the link to their site, also where did you buy the pressure release valve at .
We are still waiting for the answer to where you got the bleed valve. The right type are not easily found.
Is it 1/8 NPT-M10 -BSPP etc. .Keep up the good work we all appreciate your vids.
very good vidio
Contact the manufacturing and they will send it for free just like my large air filter with no fuss. Awesome people to work with.
Excellent video ! can you let me know what kind of molecular sieve you use ( 3A, 4A, 5A, 10X, 13X ... ) ? Also what is the bead size ? I have seen bead sizes from 0.4mm to 6mm being sold.
Thank you, Did you fill the barometer with anything?
I watched this video and bought one, barometer keeps swinging quite alot and i believe thats why it fails to stop at what you set
Back in the day when I was scuba diving frequently, there scuba shops when filling the tanks would fill the tanks partially submerged in water in cement walled vats.I expected this to be used to control the temperature of the steel tanks while filling. This was only partially true. As cooling was beneficial, it was also a protection if the tanks were to rupture. Having the tanks partially submerged at the time of filling and failure,, the force would be absorbed partially by the weight of the water and the barrier of the cement walled vat. I saw photos of such failures. So at the time, this was the method of precaution that industry was encouraged to do. Looking back on this method and thinking on the lines that forces must be applied by a medium. For example an explosion in air which does not eject debris only the force. A great amount of that force is diluted from the compressibility of the atmosphere. Take that same explosion under water and within the same distance, the damage is more devastating. This is because the water is not compressed and the forces are not diluted. Would the water and cement in the containment vat become a media to transport the energy of the exploding tank? SoI don’t know. if the volume is low and the bottles are secured so they don’t go flying around the room, is there a significant danger?
I don't think your tank would rupture
Yes, they are CE(liable(liability) if something goes wrong). Just don't buy clones, trust me on this. Big lesson learned.
Best thing to do is to get a one way valve foster male connector, so that you can simplify the shoot-off procedure.
CE does not provide a guarantee for anything.
All companies producing anything must provide a CE implying Certified European standard merely to sell their products in the EU region.
It is NOT a guarantee or warranty of any kind and one could in fact "self certify" as well.
Much like ISO 9000 quality assurance saying "-I followed all rules but you have no way of checking I am truthful".
Great video.
Safety is always first Hiding behind fridge is called you value your life and i would do the same. I have seen what just 300psi can do to a human. Guy at work came up with this brite idea on 3rd shift to use pvc as a secondary tank with glued caps. We had no clue to what he did when we came in on 1st shift. until we turned the compressors on to p-restart up the machines, well his brain storm exploded hitting women employee in shoulder she was very lucky it could have been fatal. It was very bad. So long story short this is high pressure that is 100% worse . Any of these units i would not trust and would advise taking all safety steps to less the chance of a problem.
if you scare that much you can use cement and build like a case around it and let some
holes to turn it on or off
I am in Cornwall UK. Some good tips there on HP safety.... however, I used to test these cylinders and as long as no water gets in they are good, oil is breathing air safe (or should be) so should not cause fire. Those compressors are fine in UK!...... I tried to burst a 3 liter Faber bottle on purpose...got to 590 Bar with water and I couldn't do it!!,.I have seen these cylinders dropped down sea wall steps and they been fine unless the valves catches then it can be like a unguided missile.
The Oil you put in it should ONLY be Breath air comparable, Anderol 555 (is best) or Bauer N28355-5, change oil as often as you can afford !
Normal hydraulic oil will start a fire easy....
the oil and water filter you have shown is doing its job as all compressors will pass some oil. Always start compressor with all bleeds open and also when shutting down.....Go to a Scuba centre and ask how they run theirs!!!
DO NOT PUT ANY OTHER OIL IN OTHER THAN COMPRESSOR OIL IN IT THAT IS SUITABLE FOR BREATHING AIR!!!
GOOD Video though!!
Thank you for the great information. What do you think: is there any way to pre-filter the air before it goes into the pump? Is there any type of filter setup that you have heard of that could be used as a pre-filtering setup? Much appreciated.
Yes, I have seen some setups that use desiccant at the gold mesh filter to dry the air on the airgun forums but imjust did a video showing that it's not necessary as the gold dryer with bleem valve produces zero moisture in my 88 cu ft SCBA tank
UK approved .. stamped with the British standard ce mark
Did you ever add a high pressure valve to the top of the cylinder to bring it up to high pressure per joe b ?
Is there instructions for installing the relay to upgrade the compressor to set pressure autostop? I have the new relay version but couldn't find any insight on installing it.
yes when compressor gets up to required pressure and shuts off (or you shut it off):
First shut the valve on the bottle
Then bleed the systems pressure out through the bottle bleeder
This releases all the pressure the same direction as it is pumped, by bleeding the system at the compressor end as you recommend is wrong, doing it this way is pushing all of pressure left in the filter (moisture ect) back into the compressor.
Always release the pressure at the bottle bleeder if available.
I guess when filling a rifle directly, you can only release pressure at the compressor end though.
Hope this helps.. ps I have a Omega Supercharger with a diablo dry air system filter..
Glad I found your video. My Yong Heng is arriving today. I will order the filter components ASAP. What oil do you use in your compressor? And no, I haven't searched yet, but does your earlier video include details on initial setup of the compressor? Thanks!
Jim Mellon yes, check my other video for some detail on start up. Use aw46 hydraulic oil
Thank you
The compressor I purchased has the auto shutoff. I simply set the shutoff level at max, over 5000 psi on the gauge, then do a safe manual shutdown when my gun/tank reaches a pressure well below that. A question though, how about putting the desiccant on the low pressure input side, you could make the entire tube out of PVC and avoid it having to maintain high pressures? Or would it suffocate the low pressure input?
Is there anything to stop the moist air passing around the outside of the tampons in the larger filter, thus bypassing the filtration?
Hello sir... thanks a lot for your informative vid... appreciate your effort ... How do you find this mini compressor so far? .. is it working good still? ..
Hemn Mahmmod yes, still working fine and it's been about 6 months.
Whats everyones thoughts on using an anti-freeze solution for coolant with these compressors? Surely a good quality anti-freeze will stop rusting of steel parts, & pitting of the aluminium components. ???
Yes indeed stops galvanic action where there’s different materials.
Almost three years after you posted this video. The compressor would not be as popular if it would blow up all the time or hurt people.
I just filled a 10 Liter 300 bar bottle to 200 bar in two runs and will continue tomorrow.I don't have the room to set up a protective wall but I position the compressor so that it can throw parts away from me, if something goes wrong.
I am using the unbranded version .... again. They have been selling this for years and it works if you handle it with respect and follow the manual. I am more concerned about that 10 liter bottle once it is filled to 300 bar. Now that is a bomb but those steel bottles stand around construction sites in full sun light all day long .....
Here's a way to put together a one-way check valve so that you don't have to worry about which valve to shut first. The check valve only allows air to flow in one direction. This configuration will end up as a male-male in-line check valve. You can use it between the compressor and the tank, or anywhere you want air to only flow in ONE direction. It's clear that you need to open the two bleed valves on the compresson BEFORE you shut off the compressor, to lengthen it's life. With the check valve in line, you can do that WITHOUT losing any air in the tank. Here are the parts:

airtanksplus.com/product/male-foster-fitting-with-female-14-npt-threads/
Might need an O-ring for the junction of the two parts. Not sure what size (I'm new to all this HPA stuff ... less than a couple of weeks so far)
Harry
midiman1007 thanks! That is an awesome solution to that problem.
But how does one vent the pressure between the check valve and the rest of the line to the tank?
@@tomredmond the tank has it's own bleeder. The compressor has it's own bleeder
If i ha a 220V plug in I would have bough that one over the 110V version
It works much more efficiently and has the auto shutoff feature.
Where did you get the T fitting and the bleed valve that is attached to the carbon fiber tank?
It’s possible with some experimentations that Cat Litter will remove moisture and odours if tightly packed between the fibre filters.
Could you use a pocket of silica to remove moisture in the middle?
Where do you get the large cotton replacements for it? Great video and information
Ouncan them on AliExpress or ebay
the way I been shutting it off my yong heng compressor , close valve to fillstation tank first , quickly bleed compressor, and shut compressor off , I have the exact same one
With these compressors you should always put your tank above the compressor as high as possible that way the water trickles down back toward the pump rather than into your filter and tank.
Hello.
a question: at how many psi, should we load the cylinders of air, in order not to suffer danger? (a maximum limit)
Thank you.
With O-rings sealing the pvc tube inside the aluminium tube aren’t you pressurizing the pvc pipe to ~4000psi? Is it rated that high? Have you noticed it deform at all?
Can these filters be used on a hand pump? Do you think it would make it harder to pump? Or do you have a better solution for hand pumps? Thanks
HI, so I have this same compressor, and I Just purchased the GOLD Tuxing (3) stage filter..first it is the cotten, then carbon, the silica, then dissicant. My only problem is WHICH end of the Tuxing filter connects to the compressor and which end goes out to the air gun/air tank? Which stage should come first in the tube? I am assuming the cotton should be the first in line.
I believe the cotton side comes first and the charcoal side is last. The cotton will catch the dirt and large particals. The desicant is next and charcoal to clean the smell.
When I received mine I had to open it up. help get the motor started. yes oil is in it. this machine has it problems ,but it's do able more me cause I work on motors a bit.
I heard they now sell a 110 v version that has the automatic shut off I can’t get a reply from the seller just yet it’s confusing trying to purchase one on Ali express I also see another brand that is a gold version called tuxing. I’m ready to purchase one ASAP also I see Ali express sells scba tanks with valves for filling pcp guns, curious if they are any good ?
Zachary Richards mine is the 110v auto shutoff. Buy it on ebay and you will have buyer protection. Not sure if the AliExpress valve are any good? Again, I bought my fill station valve with 36" microbore hose on eBay.
Hi Air, I just received that same updated relay from Aliexpress. Did you get one of these yet. I see where almost all of the wires go. If you are looking straight on at the connectors, They have doubled up the top left wire. Just a little unsure what to do with that one. If you could, Just let me know if you have done this yet. Thanks
Steve Judd no have not swapped the AliExpress one yet. Still using the eBay power relay. Lost the auto shutoff feature but I'm ok with it for now
It’s possible with some experimentation that Cat Litter granules packed between the fibre filter pads would absorb moisture and remove odours.
There are so many comments I gave up trying to read them all. However, the pressure relief you call for water/oil is actually the low pressure side valve. The proper way to deal with it would be to start the compressor, close the high pressure bleed, leave open the low pressure side. Run the compressor until the high-pressure side equalizes with the tank pressure. At this point close the low pressure side to begin actually filling the tank. Another commentor talked about a one-way valve which is not a bad idea. At the end reverse the procedure. Obviously you will be opening and closing the tank valve at the appropriate time. There is no reason to have backflush air toward the compressor
Jerry Kornfield thank for input. I went the way of the one way valve near the tank. It so easy and no air get wasted. Plus it allows me to to bleed the air before shutting off the compressor. Works beautifully. All the best!
Regardless, the actual company says to pressurize the high side first then close the low pressure side to actually start filling, 1 way valve or not. When you hit the target volume, the manual says to open the low pressure side to stop the filling. Also, open the high pressure side bleed before you turn off the the compressor (that is also right in the manual). They say it will prolong the compressor life!!! Soooooo, why do they sell a auto shut off version LOL LOL After reading all that, I bought the basic version (partly on help from your initial video and from Joerg Sprave.
You are correct. I no longer have the auto shutoff feature since my power relay burned and I replaced it with a similar power relay but lost the auto shutoff feature. By default I have to bleed the valves and then shut off the compressor. I use my compressor at least twice a week for the last 7 months and the piston orings have not lost must in the way of ability to pressurize my tanks.
This is what my friends are using for their systems like yours… www.aliexpress.com/item/yongheng-air-pump-Accessories-update-version/32834008091.html?spm=2114.10010108.1000014.15.3e5d2795sOHtcL&traffic_analysisId=recommend_3035_null_null_null&scm=1007.13338.98466.000000000000000&pvid=cccf9cef-44b0-4f71-a30a-9b2a6561ea6b&tpp=1

Dear Sir,
Is molecular sieve what we normally refer to as desiccant??? Desiccant has the unique feature of being reusable when spread over a plate left in a warm oven in order to dry out the moisture soaked in during use. Vey interesting & well explained video. keep up the good work. Kind regards.
ToolsConsumables not sure exactly but molecular sieve is supposed to be the best for high pressure
Dear Sir,
Many thanks for your courteous reply. desiccant is usually found in electronic equipment ( cameras, mobile phones, computers, other delicate components ) that must be kept absolutely moisture free. It's normally in little bags that look like corse salt grains (in a pillow shaped transparent bag). One can purchase large quantities as well as tiny amounts online. Kind regards.
ToolsConsumables My work was in a oil refinery the last 37 years. Our unit controls used air. It had to be dry. We used desiccant in big twin tanks . One was heating up and removing moisture while the other in service. They switched every 2 hrs. We used large amounts of air. So yes desiccant will work . The desiccant we use is around half the size off a BB.
Dear Sir,
Many thanks for your courteous response. I wasn't too sure if what Americans call molecular sieve was the same stuff as I 've never heard it in the UK. But many thanks for your comment. Kind regards.
My pvc pipe doesn't fit snuggly into the filter, it's too loose, about 1-1.5 mm loose, so to prevent the air channeling, what if i put the molecular sieves into a sock and a rubber tube (maybe a long balloon cut on both ends?) add the shorter tampons on both ends... will it protect the filter from the acid build up? any suggestions?
stoner27th that sounds good to me. It's not so much about the acid build-up but more about the molecular sieve touching the walls of the aluminum tube. Supposedly the acid that could build up from the molecular sieve is only bad if it touches the aluminum walls of the two as long as you are insulating the sieve from the two it should be fine.
Okay.. I'll try sock and balloon.. now.. where can I get those long balloons... wait.. condoms! .. LOL..
the needle in my YH pressure gauge does a 'hummingbird' vibration when getting close to 4000 PSI. Has anyone experienced anything similar? It fills up my 4500 PSI bottle just fine. Could it be that the gauge was drained of oil when it was shipped to me? Does anyone know if these gauges are filled with glycerine or silicone oil (clear fluid) ?
If so, is there a way to fill it up with some ?
Rogue-Spear it’s filled with glycerin should be a rubber plug on the side of gage.
The volume in the hose and compressor is not a worry. Just the tank could be the only thing that is dangerous.
Hi i have a small silver oil/water separator with the small cotton thingy inside and also ,i had bought the cheap black oil/water filter and it came with black charcoal on one side and i am always getting water inside my rifles.
Should I use both like You did in the beginning of this video?
also what exactly can get ruined inside the rifle besides the Aluminum
parts like in the Armada or Hercules
Someone told me to remove the charcoal.from the filter , Should i?
Now that you've had the compressor for a year how is it holding up? What problems have you encountered with this compressor?
What kind of oil for lubricant do you use in your Yung Heng compressor?
I was just wondering if those harbor freight o-rings held up because you want that inside pvc real tight...have you had any oil on the outside of the pvc? I'm looking to get the same compressor. But I'm thinking about actually making a longer filter than that. Also wanted to know what has been the longest run time that you've got out of it and if you used ice water or does the instructions say not too? I don't know if that would cause more condensation or what have you maybe somebody else on here might have the answer to that if you don't. Thanks for your time because I can't wait to get one.
The orings should be 70 duro meter and 90 is best. Not sure if harbor freight has those orings. I never run it more that 20 minutes. I have run it for 30 minutes but it really wears thing out even when I use ice water and keep the temperature around 47 celcius.
@@AirVelocitySport Thank you for the input.👍
Hi
Can we use silica gel in Between cotton?
Silica gel also very effective in absorbing moisture in air
Yes, I know of others that use silica beads but they dont last nearly as long as molecular sieve.
Why not just pour the molecular sieve directly into the tube like the Diablo filter? Is molecular sieve better than silica gel?
According to what ive read moecuoare sieve can cuase acid errorion over long periods of time compromising the aluminum tube wall. Could be dangerous
I appreciate the reply, I just ordered a filter from AlliExpress that already has the Molecular Sieve inside a plastic tube similar to your setup. Thanks!
I read that someone was also using rice and says it works. Pretty crazy stuff but if those filters come out dry are you still worried about moisture?
Hopefully you will be able to respond to this what size filter core goes in the black separate ?That you are showing in the video. Also where do I purchase from thanks RS
I am going to do this hack but by putting in that pvc pipe, wouldn't the air just revert that route and some through the molecular sieves? How about just putting the molecular sieves in and putting the tampons on the ends?
Where did you buy the cotton filters? Link please.
excellent video!could you make a disassembled guide or maintenance guide?
eclampsie thanks! I'll probably do one as soon my unit needs service.
great! i am french so i can t understand everything. could you put on the description od of you pvc pic and thickness?same thing for o ring that you use.it could be easier for all beginners ;)
I bought a compressor a coupe of weeks ago, and now I just bought this filter. Buying from china is a bit freaky, the compressor was in Cali, not so freaky. Is there a foster fitting for the hose end, or just buy a male to male foster fitting??
On one end is female Foster and on the other is a male Foster. Very nice
Showed up today, nice little filter, looks like I won't be going to AOA any time soon, I have my filter hooked directly to the lil filter on the compressor unit, eliminating the hose that came with the filter.
Hi. Like your videos. Wonder if you could help me? I have the same compressor but although it has worked OK for the last 18 months with no problem i now can't get the pressure above 210 bar instead of 300 bar. I would be very grateful if you could give me any advice. Many thanks
What compressor do you have 240v or 110v. Does 110v have auto/shut off?
usa 43 I have 110v with auto shutoff
I think you should choose the most expensive one they call it SET PRESSURE type, the AUTO SHUT OFF type is just the name for the fail safe burst disks system. cmiiw
you will get a good system with just the use of silica beads.
Where do you get the replacement 1.5 inch the big long cotton tampon replacements
Don’t no if they are certified safe in the uk ,, but people are buying them and using them as well as other brand name Chinese ones , cheers Shane uk 🇬🇧
Yes I do not even know if they are certified safe in the United States of America. when I first started using this three years ago I was afraid something bad would happen.someone then mentioned to me that if something goes wrong with even one unit and someone is hurt or killed they will never sell another unit. so it makes sense that the Chinese make sure that this unit is slightly over engineered for safe use. the block & head cylinders made in China are no different than those used inventory or Hatsan compressors.
Good work once again desicant is expensive if the gold tube stays cool there isn't much moisture in the air it'll put heat in that tilt the gold tube tword the inlet if water is in there it'll settle to the bottom is there a difference on a high vs low humidity day? and thanks for the heads up on the relay the more people that buy those the cheaper the replacement parts will be and ya competition is for the benefit of all knowing the when to replace what or for the lack of a better expression a maintnence schedule, thanks for the pointers
Where can replacement cotton filters (the original one) be located?
I put a one way foster in between. No air lost.
No problems with this Tuxing water trap Sieve? Have you tried any other ones.
I have a 60 minute draeger tank. May I ask where you got the base on the bottom of yours?
Handle, bottom cap and net on amazon
Hello, my only concern about that is if the water filter that you build has the strenth to support this level of pression. Maybe would explote?
Francisco Cabrera it rated to 4500 psi working pressure.
Best way to keep water and air out of your gun is to turn the air bottle upsidedown and purge the air and moisture. the point the gun in the air and fire a few dry shots.
does using the secondary filter add extra load to the compressor and bleeding become a little longer
No extra load just a little more space to fill on initial run and thus more air to bleed but no big deal
Any way to put the moisture trap on the compressor input side?
LouB yes, I have seen some video put dryer on the lower pressure input but you still need a high pressure trap because compressing air at high pressure creates water at the piston. I would imagine that low pressure dryer should help reduce moisture but not eliminate it. Good point.
What about using the media that's inside the diablo drier from aoa???
Lily Smith I don't know what's inside the Diablo but it must be ok. I' m using molecular sieve because it is supposed to be the best for high pressure air but I'm sure other media should be fine.
Ok, thanks for the vid, good mojo. I bought that tampon filter last night, and a male to male foster to go from the compressor to the tank/filter. I'll have $400.00 invested into my filling needs, looks like I will have a $1,000.00 saved . Great deal..
