Here I show you a mod to make your air compressor a few decibels quieter. I reduced the noise by 4 decibels. What's left is mostly valve noise, and that noise can only be reduced by putting a wall between me and the compressor. This technique will work for any compressor, such as Eaton, Polar Air, Ingersoll Rand, Campbell Hausfeld, Quincy, etc. This technique will not affect your cfm. - วิทยาศาสตร์และเทคโนโลยี
The "Silent Air " is is a large box with a large air filter since they are removed from the head . The larger and more free flowing you can make it and the farther you can get it from the head the quieter you can make any air compressor. In the old days we used to just pipe the intake thru the wall to the outside with a filter and presto - Quiet air compressor
Thanks for sharing. A buddy of mine has a rather nice stainless steel bike silencer at a jaunty angle on the outside of his workshop for the job. Looks cool and I testfy that it makes a big difference. Again though, why so many 'dislikes'? Perhaps those who dislike could comment to explain their reasons rather than just throwing sand in the works.
Great video, thanks for taking the time to show people a quick simple modification that helps a little bit.
You're welcome
I once had a dirt bike with an expansion chamber and I welded an adapter to an old VW Beetle exhaust tip then pinned the adapter into the expansion chamber. Huge improvement. Thanks for the ideas!
You're welcome. Thank for your comments!
Very well done, never have heard of this or thought about it. Thank you!
Thanks!
I bought a KOBOLT 60gal single-stage compressor many years ago and placed it inside my attached garage. Soon I found that the noise was impossible to endure. Being inside my garage was the problem. I moved it to an outside concrete slab which significantly reduced the sound. For my neighbor's benefit, I installed a six-foot high PVC fence with a gate to enclose it and direct the sound upwards. Lastly, I mounted a retractable awning to provide weather protection. When the compressor is being used, I fold the awning up. This was a good DIY project and not expensive to accomplish.
That's always a good idea. If I had the money, I'd have a compressor shed.
Great idea!! Huge difference!!
I have just always ran my intakes outside with a turn down. Never considered the use of a muffler. Great idea thanks for posting.
You're welcome. I'm glad it helped.
Really cool low cost noise reduction setup, I do not have the type of compressor you have but I will set mine up the same way, thanks guys.
Thanks for your comment. I'm glad it helped.
This compressor uses a pump made by Eaton Compressor, many brands use this like Emax, Polar Air ETC. It's servicable and reabuildable.
Used to work for a company that designed cogenerator plants. Used rooms full of 454, 502 or 540 big block Chevys run on LP gas to run electrical generators. Most were in public schools. So how did they silence a room full of normally loud car engines? Car mufflers on the exhaust stack and intake piping. Technically they were called "sound attenuators". Looked just like a big SUV muffler to me. Nice work showing others how to do this.
Thanks. I'm glad you liked it.
I did something similar years ago. Probably in 2002. I put nipples in the heads and removed the filters. I then fabricated a box that accepted a flat automotive filter. Ford powerstroke if I remember correctly. The greatest part of my design was I actually need no muffler whatsoever. I ran a 2 inch pipe from the box through the wall to the outside of my garage. This serves 3 huge porpoises.
1. The noise is outside, and believe me, that pipe is noisy out there. Be sure to place a screen over the end to prevent birds, mice, etc. And put a downward facing 90 to eliminate moisture entering.
2. Cooler air is less dense. In the summer my garage gets very hot especially near the hot compressor pump. Not only does the outside shaded air intake help keep the pump cooler, im sure the cooler air entering the hot pump has more expansion and thus, though perhaps meniscal, gives the compressor greater efficiency.
3. When im sand, painting, or any other dusty dirty work, the compressor is always gets clean air from outside instead of dust from the shop. This reduces filter services and thus prolongs the life of the compressor. Also the automotive filter has much finer micron catching abilities than the original filter with far more surface area.
This is exactly true. Winter time air is nice and dense, and helps keep the heads cool. I recently uploaded a video of this. th-cam.com/video/kV5KmBlcXmU/w-d-xo.html
Great idea, thank you! Can't wait to try this on mine. I love creative solutions by creative people who are kind enough to share such with the public. You've now gained another subscriber! :)
Thanks
That compressor looks beast mode.
Thanks for the tip. The compressor for my powerplasma cutter is so noisy when it kicks in.
Great job
Wow! Fantastic idea with a car exhaust muffler👍👍👍
Big difference, worth the effort. Lots of compressor noise comes from the tank. As air exhausts inside the tank, it sends sound waves through the compressed air in the tank, and it whacks against the tank. Try putting your ear against the tank and you will hear a metallic drumming sound from compressed air hitting it (among lots of other loud mechanical sounds). The solution is Dynamat or similar sound deadening sticky mat. Will make your tank ugly for sure, but may be worth the effort. Note that some compressors have a diffuser inside the tank to quiet it, others just dump air directly into the tank. So results may vary. I can tell you it worked fairly well on a 10g cheap-O.
Thanks for your comments. I have another video where I build an enclosure for the compressor. I hadn't thought of dynamat though. Good idea.
I like the ball valve on your oil drain too. It looks like you're taking care of your equipment. Is that a drain extension on the bottom too? I wonder if some foam sleeve used to insulate plumbing would make your hoses leak even less noise. You could use 2 smaller lawn mower mufflers if you wanted to, but I don't know how well they work, and you already have that muffler. Some people hang moving blankets like tapestries around and above their compressors, but not attached to them. Just a thought.
It has an automatic drain on the bottom that drains about every 45 minutes for three seconds. Keeps internal tank rusting to a minimum. I have a newer video where I show further refinement to the muffler setup and build an enclosure around the compressor, which really helped.
2nd that. Good results. Thanks for sharing.
Thanks :)
If you run the pipes outside, that will make it even quieter, the longer the inlet pipe the quieter it will be. With regard to fitting the pipes into the car exhaust, you can use expanding foam, if you are careful. I've used both of these methods and they both work pretty well, I used a box with foam filters in it. It's nice to see a well made, well presented, common sense video.
Thanks. I'm going to run the pipes outside this summer.
The trick is to take the whole thing and put it in your neighbours garage and run hoses and wiring to your place
You can also buy foam specifically for sound deadening
I used Tribo-MAX treatment on my 80gal 5HP it's 20-50% quieter.
if ur air compressor keeps up with air requirements change the pulleys out and slow down the compressor speed. i have an old standup compressor running half the speed its so quiet u can talk normal while standing next to it.
ive got the same compressor with the whisper box on the back..mines and "emax" tho...not polar air..
That's a great idea. But I don't understand this continuous run mode, I've never heard of it, why is it louder?
Nice trick
Those are the best compressors slow rpm. High output I. Love mine it's got a deep throaty sound like my motorcycle!
They are nice. It's a real work horse.
That’s awesome I would’ve never thought about that I know what air compressor sound like and I can imagine in person it must make much more of a difference that’s cool thanks for your video
Thanks. The camera mic doesn't pick up the lower frequencies put out by the continuous run mode.
Fast and easy to use
Nice Idea!! I have a few extra mufflers laying around.. I'm going to try this! By the way, what size is the ball valve in the oil drain port?? Thanks!
Aha! So I am *not* the only person who, years after I bought my big air compressor with a 60 gallon air tank, still have it standing on the skid it was bolted to when I bought it! :-)
I ran my first compressor from the nineties like that too. I sold it last summer with the skid attached. With this new one, the only thing I did was put 1/4" rubber pads under each foot like the instruction manual calls for. In a newer video, I use the skid as a foundation for an enclosure for further sound reduction.
that voids the warranties
I not only left mine on the skid but, I put casters on it. Now I can move it out of the way when I'm not using it or to clean behind it. I also cut out the center so I could install a mechanical self-emptying water trap. Works great. I think I'll add the muffler too after watching this video.
They won't warranty the compressor on the pallet...
ya'll have to be skidding me???
If your worry about noise put the compressor out side with sound proof walls around it and run the switch in side the garage .
There's a noticeable difference but not as much as I was expecting, I'm curious what's the decibel readings would be?
The difference is more noticeable in person, as the mic on the camera doesn't pick up the lower frequencies well at all. I am getting a little over a 4 decibel average drop, which is a little over a 50% reduction in perceivable sound level. I'm working on another video to show another modification to lower it further.
I use an automotive air filter inside a insulated coffee can.
They are a family company the staff are Awsome I have one and purchased one for work
I went out to Ohio to pick mine up. They were nice people.
I've got try this on the compressor I use for my Everlast plasma cutters.
Another Neverlast Spam to try and sell a substandard POS Brand.
We are in 2022 and we still use gaint loud compressor? Something it doesn’t seem right
Now, take those tin filter filter housings off and take a took at the fitting connecting them to the head. The pnes on my compressor were very restrictive. Replaced the entire housing with a pipe nippled screwed into the head and a filter sandwich between 2 pieces of aluminum plate. I don't remember the number, but I took a decent amount of time off the compressor's recycle time.
That sounds like a good idea, to sandwich a big filter between two plates like that. I might mess around with that in the future. I did end up taking the tin housings off later on though. I screwed in 1" street elbows into the head, and then made a big filter from a large suction strainer wrapped with 3 micron polyester filter material. The setup is similar to what the factory uses. I don't know if it has reduced cycle time. I never checked.
Good Idea! You could also make rods longer and stack a bunch of filters together.
you could pipe the sound out thru the wall for even less noise.
I did some reading and asking and I don’t know for shur but I was told that is will burn up the head reeds because air flow restriction
This compressor doesn't use reeds. It has poppet valves instead. The factory uses a setup like this also, so it should be fine.
I honestly didn't notice much change to make it really worth the expense of a muffler and parts to rig it. I do think you have a good idea though. Let me ask you this: if you listen to your video of it and then go and listen to it actually running, is there a difference more audible in person than on the video?
Makes a big difference. Cam mic isn't good for those frequencies apparently.
Very good. I may pick up an inexpensive muffler and give this a shot. The wife does nothing but complain about how loud ours is.
What's the intro song? Thanks!👍
"Gift of Blue - Guitars" from audioblocks.com
How many dB does the compressor register?
Maybe it's just the audio but I think I like the way it sounds much better without the car muffler attached. the bassy rumble is what I love about this type of compressor.
I like this. I use my Everlast plasma cutter as much as I can and I get kinda tired of the compressor's droning in the background.
Hey, You just made your compressor work harder !!
The pump is definitely working harder, the motor it's probably negligible. If you're in a dirty environment this might be worth it just to pipe your intake to somewhere it can get clean air.
I put mine out back built a room for it.. don't hear it at all..
Excellent
An intake muffler is constructed differently than an exhaust muffler.
AMAZING INTRO what is the song ?
It's called "Gift of Blue" from Audioblocks.
I really have to agree with you, at the beginning I was expecting the rest of the song....
The start was good......
See now i've been thinking about this topic for awhile wouldn't an automotive intake from a luxury vehicle work better? Not only is it built with baffling and chambers to quiet induction noise just like from a compressor but it also has an integrated air filter. Im going to hit up the local pick yard and test my idea.
I now use an air box from a hemi. The lines are plumbed through the wall. The air filter can handle any cfm I throw at it. I have another video showing it.
just put the intake outside. drill a hole in the wall attach a wide pipe with a air filter on the other side.
8" concrete block, or else I probably would've.
i AM PRETTY SURE THAT I SAW IT AT Harbor Freight but, They have this air line connector that is blue & it splits one 1/4" hose into two but, I was thinking of a part that was already available but, your hoses are much bigger then 1/4" air line!!! Same idea though, 2 openings within a round base to shove down into the muffler/exhaust pipe. I am looking for a Good, CHEAP, very quiet air compressor for my brother/ he lives in an apartment & the neighbor has kids so, He needs a very quiet compressor to air brush at night time without disturbing anyone else & to do so on a very tight budget!
I ran mine through wall to the outside,, now I get only fresh air and really quieted it down,,, if you have access to the outside you should do the same and I put the filters outside also..l can tell it's much quieter then your muffler setup with no risk of restrictions. And I also put a 1/2 inch roll of copper tubing between the compressor pump and tank eliminating almost all the water the comes from the 200 degrees air entering the cooler tank causing condensation,,l have many drops with drain values but hardly ever get any water after doing the tubing..seen many useing oil coolers that restricts the flow due to the coils size reduction,,and as I figured alot of them are having pumping issues now due to back pressure on compressor head..just a suggestion I like to pass on what really works..
I have the hoses going outside now too, so it draws in cooler air to help lower compressor temps. The chugging sound is now outside. They connect to a hemi air filter box with bulkhead fittings. It has a screen over the intake to prevent mud hornets and birds from nesting in it. My ram was totaled last summer by a tractor trailer, but I was able to save the filter box for this. I also run a large fan cooled aftercooler and custom condensate reservoir with sight tube and drain after the cooler, and before the shop regulator. It has completely eliminated any line moisture issues in my shop. My compressor tank also has an auto drain which prevents tank rust issues. Thanks for the suggestions.
You mean you replaced the existing tubing with 1/2 copper or you mean you rolled copper tubing around the existing tubing as a heat sink?
@@jsplasha connect one end of roll to compressor head and the other to the tank, roll will be 25 foot long l used a 5 gallon bucket to wrap it around to make coils smaller and mounted it behind compressor fan,, put a 1/2 inch water separator on tank end of coil,, and will solve water problem.
@@jsplasha I actually hooked up a hydraulic hose to the existing pipe from water separator with flexible hose
What about for a smaller compressor like a gmc syclone 6310? Can you do something like this?
It should work on any compressor. I now have my intake lines running outside the shop to a auto air filter box, so all that noise can only be heard outside.
I ran mine through wall to outside and put the filter there , very quiet and no dust from shop
That's what I'm doing next.
@@ArnoldsDesign oh,,you like my idea,,,lol glad too help,,,another one put a roll of 1/2 inch copper tubbing between compressor and tank, it dropped my air temperature by 80 degrees greatly decreasing condensation from hot compressor air entering cooler tank,,
3/8 inch will restrict flow and volume causing back pressure on compressor head and shortening life of pump
I would be worried that the hose would cause restriction you should check heat value before and after installation.
It doesn't cause any issues that I know of. The factory also uses a hose to muffler setup like this one. I don't recall now if I did a head temp check before I hooked up the hoses, but I know I got a 50°F decrease after I installed a box fan blowing down on it. That's in my second air compressor video.
Arnold's Design, cool, pun intended. It seems that the fan is a great add on.
Can you explain how this does not affect the CFM?
I can not, but I've noticed no performance loss during blasting.
I am going to add that to a couple of compressors hooked up to a fire suppression system.
I have newer video where I build an enclosure for the compressor which makes it even quieter.
Why not just route the intakes outside the building and make a screen to go over them to keep bugs and stuff out?
It's been like that for a couple years now. I used the air box from my hemi ram that got crushed by a semi in my parking lot. But my loss is the air compressor's gain. The filter seems to handle the 36 cfm with no issue. I put fly screen over the intake to keep out crawling things. It cuts intake noise completely. You can only hear a low pitched wop wop wop sound outside when it runs. I think I posted a video about it too if you want to hear the wop wop wop sound for yourself.
Didn't notice much difference.
Maybe in person it can be noticed, but, not on the video.!
I don't know if its because i have headphones on, but i can clearly tell a difference.
Use some spray foam to seal the tubes to the muffler
I have another video where I show further improvements to this setup.
I need to buy a compressor to replace my old one so i want to upgrade. My problem is this new one has amps I’m not sure that my electric for my old compressor will hold. Any advice? Any is welcome and appreciated.
I’m buying from northerntools.com and it’s a Emax industrial plus silent air 10hp 2-stage , 80 gallon vertical air compressor with silencer 230 volt , 1 phase. Model# ESP10V080V1. All it tells in specs is operates at 40Amps, suggests 60amp breaker and it takes 80amps to start.
I have at home 8/2 Romex that i was told is good for 45amps. I have 50amp 2 pull breaker and i was told that will be fine the 60amp is just a suggestion. My real worry is this 80amp start up. I’m not a electrician and don’t want to burn down my house or shop.
Emax and Polar Air are both Eaton pumps, and I'm pretty sure they are the same units with different branding, because the silent air box is Polar Air's creation. I have the same rated unit as you, but Polar Air. 10hp 2 stage 1 phase, 80 gallon. I went by the installation part of my manual and connected to a 60 amp double pole breaker. The 80 amp startup was mentioned too, but it's only for a fraction of a section, not enough to overload a breaker or line. I forget the wire gauge now, but just follow the instructions on that. I have over 350 hours on mine now with now problems whatsoever. If you can, get the hour meter for oil changes intervals, and definitely get an automatic tank drain. It will save the tank bottom from rusting out.
Edit: I just checked my comp's electrical box. It says run 4 gauge if cable of 100 ft or less, and 3 gauge if longer.
Arnold's Design thank you that helps a lot. I searched for the oil change meter but it keeps sending me to information on oil changes not a meter. Should you have a link? Thanks again
@@bjputvain I'm glad I could help. I looked on Polar Air's site. I'm not seeing the options to add on the hour meter or the auto drain now. I bought mine in 2017, so they've changed the site since then. You could just call them and ask about it. They were nice people when I dealt with them. I went to the factory and picked mine up. If all else fails, you could just get a Hobb's hour meter and install it on the side of the box if you wanted to. That's what they did with mine. The auto drains can be purchased from McMaster.com.
I can clearly hear the noise reduction but it's not worth it because the compressor needs to draw in ambient air. The muffler will cause an air restriction and create more heat.
The noise reduction is much more noticeable in person, but the cam mic levels the sound a lot, so it dampens the effect.
Arnold's Design. I understand that the noise reduction is important to you.
You really want a bigger filter.
It’s called an unloader valve. Most good compressors have this.
Please what type of oil?
Just compressor oil
@@ArnoldsDesign What is the oil standard or size?
@@ArnoldsDesign Is it automotive oil or hydraulic?
@@user-qj4zo1xq1x It's just labeled "air compressor oil". Get the oil for pistion compressors.
Why don't you just fill it with silicone instead of the foam
So, you made a vacuum cleaner. lol
I hadn't though of it that way, but I suppose it is.
@@ArnoldsDesignIt's an easy enough fix. The compressor will last longer if it's not sucking dirt off the floor. Love the idea though.
@@MrHowieZ1973 Lol, true.
Use automotive air box
I was considering that.
All that carbon & rust from the muffler is going straight into your compressor. Inlet air is being restricted. The inlet air is being drawn in from the dirty floor. Not much of a sound reduction. To me your doing more harm than good to the air compressor itself.
A compressor needs to breath in the cleanest air possible.
Just think how quiet the compressor will be after it sucks up a dead rat and destroys a cylinder!!
It's fine.
Good lord, the things you see written on the internet.......
Tom Krause
Amen
bruh it has a filter
Normal people would vent it outside like a dryer vent, But i'm seeing this is the Pantyhose equivalent lol
The factory uses this same setup.
Because the factory can't charge you for a hole in the wall.
I don't notice much difference.
there was a difference ...cool idea. I want to know why machines make noise in the first place....yes i am simple and nieve ...I tied to google it but didn't help. It seems that all the scientists and engineers in this human race have no idea how to make machines and motors quit....again cool vid..ty
That's a good question about fundamentals. I suppose it's a collection of the impacts, harmonics, and frictional scouring vibrations.
👍
just build a sound proof box for your compressor
Yes, I'd like to put it in a separate room. Unfortunately, my shop's only 500 sq ft and there's no way I can do that. If I build a little enclosure around it, it would over heat quickly. On 50 -60 degree F days, it will actually heat my shop without the furnace on if I'm doing a lot of blasting.
A dedicated soundproof housing would have taken up more space, cost alot more than the muffler and would have (most likely) not been service friendly.
Jeff Burton not to mention it would trap heat. Compressing air makes a lot of heat. Any enclosurewould have to have built in air flow.
Please know that in my opinion, That is causing more of a strain onto your electric motor. I have the luxury of being poor & purchased a Central Pneumatic 21 gallon Harbor Freight air compressor & it has a 1/4" cold start valve which allows the first 4 pounds of air to escape because the electric motor does not have enough power to turn over the piston to build air pressure & I KEEP ORDERING NEW "COLD AIR RELEIF VALVE 1/4 VALVE'S & YET, they keep failing so, I am considering between a stubby 30 gall Kobalt tank with handle's & 2 wheels, or whether to go to Royal King & get a NOT SO MOBIL-60 gall FOR ABOUT $100.00 LESS? AT LEAST FOR NOW, SOUND IS NOT AS MUCH OF AN ISSUE FOR ME, FOR NOW AT LEAST. I will never again purchase a air compressor which has an air relief valve inline with the intake & the intake air tube, THEY ARE JUNK!!! and I am not referring to the tank safety pressure relief valve that every air compressor has for anyone who is wondering!
Mufflers goes on exhaust not intake. What you're doing is restricting airflow to your engine. I didn't hear any sound difference. You need to put it on the exhaust side. But I also there there's a. Better way than using a car muffler
??? This is an air compressor, not an engine. You can't put a muffler on the "exhaust". And no, it doesn't restrict incoming airflow. The muffler was designed to handle flow from a 5.7L V8 engine. I'm sure it can handle a 37cfm compressor.
sound same to me, not that much sorry loll,strait forward
Is not worth it bro the noise is almost the same
easy trick ... lost space and no major result. .... MY build (first compressor rated over "5cfm.." ) starting project when find 2piston seized in garbage. ( quality cast iron, estimate 12-17,cfm ) rebuilding homemade free cost connecting rod with basic tool, cut gasket homemade. try 4 motor before find who run my pulley ratio desireddd (450 pump rpm)
at this points, setup is screww on wood bench, no vibration, and no tank raisonannce with my hydrolique hose suppler (pump/Tank) no air filter. juste 12'' 1/2''collant hose, and coton linge for little filtering .((air tank find a recycling trash, and buy for 3$)
1year later. just little ajustement for maximize cfm and energie efficiency ( belt length, exemple, size of check valve, unloader line ect ect
result 45db with 15cfm mesured with formule (time,tank, ect ect)
That's how you can creat a vacuum pump
Why not place the unit outside the shop in it's own inclosure ?????? That's what normal shops do. All the way up to 100 HP and 1,000 gallon tanks. Just a thought..
This is not a normal shop. :p
Roger: Normal shops don't do that. They reduce the noise & go on with life.
To solve the noise problem don’t turn on the air compressor 🤣😂
OOOOGA BOOOGA BOOOGA
Easy? Lol
Earplugs
Earplugs make my head hurt after a few hours.
your reducing the intake flow and could cause heat build up.
The factory uses a setup just like this. I don't think it causes any issues, because they offer a five year bumper to bumper warranty. Then again, manufacturers have been known to make mistakes. One of the things I want to do is take temperature measurements with and without the modification.
The air around the motor is hotter than on the floor. So its better to use a system like this if you use right dimensions...
I can't believe that pump doesn't blow those lines off.. it must not crank out much CFM. Which is my main concern will all that line and constriction. I spent a fortune on build a compressor that can take a 90 gallon tank to 150 in under 2 minutes.. I went out of my way to make sure the runs from the pump to the tank where wide open and straight as possible. Screw noise.. its a mans tool.
It's actually pretty high capacity for vapor blasting. 38 cfm at 100 psi, 32 at 175. The manufacturer uses the same size lines for their muffler setup too. This particular muffler is from a 400 hp engine, so it can handle a whole lot more than 38 cfm with very little restriction. Man's tool or not, I want to save whatever hearing I have left.
and if u have neighbours they might not care for ur man tool noise lol
The noise isn't so bad - but it does dim the entire block's lights on start up! No joke - you can hear the pole 'buzz'.
EH! WHAT. speak up
enator71 - I saw that after the fact. I have since done some homework on this and what ppl have found is that the biggest issue when altering the intake in this way is condensation before the cylinders and water buildup. The way to do this right is to build an intake resonator with a drain. I have since seen a video where a guy welded up a nice aluminum airbox and it silenced the induction noise and traps most of the incoming moisture. I can't find he link but if I do I'll post it here.
Compressors should be outside covered up that's it.
That would've been nice.
Nice job on the connection into the muffler...NOT!!
What a waste of time lol there no difference at all🤔😜😜😜😜
Harold’s Garage O the camera trues to equalize the sound of in person it would be quieter
Well the difference is that the floor under that muffler is cleaner since the compressor is now a vacuum cleaner! Buy a noisy POS compressor and this will happen.
your restricting air flow and making you compressor work harder shorting its life................................!
Nope. The factory itself uses this setup.
No difference at all. Rubish. Give up! If you want to do something really smart keep working.
I mention in the video that the microphone doesn't pick up compressor sound well. There is a large difference in sound levels, about 4 decibels. In another vid, I reduce the sound another 5 decibels.
Sandor:What do you mean rubish? This methid obviously works. If you don't have crap in your ears you can tell. What do you have to offer TH-cam viewers other than dumb comments?
waste of time.
