you totally blew my mind with this, I was looking for some cheap diy vacuum pump because I want to experiment with building my own diy plasma discharge tube to experiment with. Sure enough I've got a compressor in my tool shed from when I worked in custom cabinetry, perfect!
The piston made of teflon will not "suck" as efficiently as it pumps due to its cup type shape. when the compressor piston moves down, it partly sucks air from the filter, and partly it is the slip through air from the downward motion. So, No , a compressor will not work efficiently in a vacuum pump mode you demonstrated, unless there is an extensive engineering done to it. I tried fitting the piston lip facing down so there would be more sucking force. It is'nt easy, believe me. I have access to a full engineering shop so was able to do it.😅
You have just solved my problem,. I need a vac pump for sealing jars of dried food, and I have the same compressor as yours, not long bought it in fact. So now I don't have to buy a vac pump. Thank you for the info.
I've got a couple of safety recommendations, if you will. These are just my personal practices so don't anyone get all pissy. First, I would be sure to install a filtered catch can (or particulate filter) before the suction inlet. The last thing anyone needs is for grit or moisture (!!!) to get pulled into the cylinders. For one, you risk damaging your machine & two, liquid doesn't compress very well without making it angry. Second suggestions would be to install a valve to relieve the vacuum. Some catch cans have drains on the bottom, but, in my experience, they've typically checked on the downstream side. I don't the engineers had this use in mind when they designed it, but I suppose it could work in a pinch. Just be careful & don't be making accidental bombs out there. Goose
Thank you, my man. So obviously, this device is not designed for such an application, and I can not recommend anyone to use this method because I did not test it long-term. So please "do at your own risk" this video is just for satisfying my curiosity.
Very cool, but I got a question: If the coupling is gonna damage the compressor when it is not connected (no air went through) then will it also damage the compressor when it pull out all the air inside the plastic bottle as well?
TBH, I had never checked it, neither for the connector nor with the bottle, to see what is going to happen, and this is just my prediction. You are correct at some point when the air inside the bottle is all sucked it is exactly the same situation and I don't think it is healthy for the compressor to keep it running like this.
It is possible to destroy your air compressor, so do it at your own risk. I never had a vacuum pump, so I cannot compare, but obviously, a vacuum pump would be far superior to a converted compressor.
Good knowlege.. question. how do you measure inlet suction vacuum pressure relative to the outflow pressure of the compressor? Is there a specific formula? Vacuum pumps generally do not specify the pressure at the outlet. Please help.. Thank you.
If you want to measure the vacuum pressure, specific gauges are designed to measure under 1 bar pressure. ( 1 bar being the air pressure at sea level, AKA atmosphere). So there will be some air pressure at the suction inlet, but because it is lower than 1 bar, it can't be measured by a normal pressure gauges. I am really sorry I didn't understand the part where you are talking about this pressure relative to the outflow pressure. If you can explain more, I might be able to help.
من از این ایده برای فیکس کردن پایه دریل کرگیری dd150 hilti روی کف استفاده کردم خیلی خوب بود. فقط یه سوال. چون کرگیری با آب انجام میشه اگه دقت نمیکردم و زیر محفظه خلأ پایه آب جمع شده بود حجم قابل توجهی آب مکیده میشد و از خروجی سیلندر کمپرسور همراه با روغن بیرون میریخت (خروجی را از مخزن جدا کرده بودم). برای این چیزی به نظرت نمیرسه؟ اگه از تله آب و رطوبت‌گیر قبل ورودی سیلندر استفاده کنم چطوره؟
I got you my friend, go check out my Oil Extractor video, I think If you use a reservoir tank in the middle no water will enter to the compressor. If you still had a question, just ask my friend I'm here for you.
As several people already asked, and I answered, first, the word powerful is subjective and directly depends on the air compressor you are using. Personally, speaking very, very generally, yes.
Thanks Bro, I think you can find pressure gauge which shows under 1 bar pressure. One more thing I forgot to mention is to open the tank valve so the compressor motor doesn't have to work both way.(only suction and no compression)
@@Nkforster Just make sure you don't use the motor for compression too, in other words, your gauge shouldn't show any pressure inside the tank, I would simply leave the compressed air valve open, the one that you connect to the tools, etc but if you use a coupling connector you should do something else, like connect an air blow gun and leave it open or just unscrew the coupling connector. I guess the water drip valve might work but that's not what I meant but I don't recommend it. Also disconnecting the motor from the tank will work for you but it's just too much trouble.
I am not sure how much vacuum you will need for air conditioning work, but if you are planning to use something like this as your daily tool for your job I can't recommend this solution. If it is a one time thing though, I think it is worth doing a little more research to see if this thing works for you. Unfortunatly I don't have any sub atmosphere gauge to measure the amount of pressure but from my experience I can tell you it easily crushed the PET Cocacola bottle.
This technic provides some serious sucking power. Obviously, the amount of this power depends on your unit performance and varies. However, these compressors are not designed to perform these tasks, especially if you are using an oil-free model like mine. I don't think they can work for a long time performing like this. So if you want to just try it a couple of times, I don't think it would be a big deal
How much suction you can get is heavily depends on what kind and type of air compressor you are using. Unfortunately, I did not have the right kind of pressure gauge to measure mine. That's why I demonstrated the sucking of the air from the Coca-Cola bottle to give the viewers an idea of how much suction they can expect.
Hi, I start by admitting I have no idea how much vacuum pressure you would need for cow milking. Also, I don't think CFM is that important here, because it means Cubic Feet per Minute, so the answer to "how much CFM an converted air compressor has?" is the same amount it had before the conversion. So you can check the spec of yours for the CFM rating. But, the more important question is how much pressure it can reduce? Usually, at open sea level altitude, the air pressure is 1 Bar, AKA Atmosphere. That's why most air pressure gauges don't even show air pressure below 1 Bar. You will need a different pressure measuring gauge that shows between 0 to 1 bar, which I don't own. Besides CFM, your air compressor also has a rating for maximum pressure, but this one does not have to do anything with the one we are looking for. Bottom line: If this is a daily task, I do not recommend this conversion for you.
First, the ones that look like this are the newer gen(relatively) ideal for small workshops like a residential area, but they won't stand long hours for professionals. Second. I guess in this scene, the squeezing sound from the bottle dominates the mic, which was closer to the bottle than the air compressor.
Thanks for sharing your opinion man, yeah venturi is nice and easy but it has no power compare to this one, it would never be able to suck the bottle like this. I recorded a video about the veturi effect recently. It will be uploaded soon. Yeah, if you insist to destroy your air compressor you can keep on until it blows, but it's just a trick, a hack...
@@kewk Thank you for sharing your opinion. I already mentioned this in reply to a few of comments, guys if you don't already own neither an air compressor nor a vacuum pump and what you need is a vacuum pump it is very obvious that you should buy a vacuum pump! This is a hack, for the situation that you already own an air compressor but you just happen to need air compressor just for a small project.
I make a vacuum chamber for degassing n removing air bubbles from epoxy resin but I'm not sure my air compressor work properly as a efficient vacuum pump !
I guess wherever you need anything less than the environment air pressure you can use this setup, and in your case, I can't see why you won't benefit from this method. Meanwhile, this method is best for situations in which you already own an air compressor but you need a vacuum pump, obviously, if you need a vacuum pump it's not very wise to buy an air compressor and use this method to convert it to a vacuum pump. I have no idea about the efficiency in both cases because I think there are just too many effective factors, like what kind of air compressor you are going to use, and what kind of vacuum pump you have...there are just too many factors. But the bottom line is if you don't have any of those and you need a vacuum pump, just buy the vacuum pump, if you already have an air compressor give this method a shot, it might save you some money. If you happened to use this setup, Please keep that in mind that this is a DIY at your own risk project, also good luck and have fun.
I made the cheapest diy ever for my little resin jewelry pieces. I got one of those brake line bleeder hand vacuum pump from harbor freight, then made a air tight glass "jar', drilled a hole on top for the hose. I have a mini air compressor from harbor as well, the tiny one that takes about 30 mins to put about 10psi in an automotive tire, lol. I want to try to reverse that until a mini vac. I got the idea for the lil hand pump from a dudes video on here.
@@charley408 hey there, I have a 25 litres 2.5 HP air compressor n I tried to vacuum epoxy resin batch with pressure cooker but it doesn't work n I searched UT video's for a solution n I found one! Vacuum epoxy resin idea just work for some kind of epoxy resin named cactus juice resin epoxy or something like that , this kind of epoxy doesn't need the hardener n this kind isn't used for ordinary epoxy based projects like jewelry n so, I found the way for remove epoxy air bubble's with pressurizing it in the ordinary 7 litter pressure cooker with installation a automobile tire air valve n a cheap air pressure gauge, u need this tools too for that ! Please be careful because compress air is very dangerous!
Great way to ruin your air compressor. Doing this will force your air compressor to draw air from the oil pan and pull it into the air tank gradually ruining your compressor on the long run. You're much better off buying a vacuum generator that takes the compressed air from one end and gives you a vacuum from another while venting the compressed air to atmosphere. It's relatively cheap and is 100% safe unlike this method.
Tnx for sharing your opinion bro, well I'm not sure if can read the the badge but it is an oil-free air compressor and It's just a hack, take it easy 😉
Guys if you are interested in this subject don't forget to check my Venturi Vacuum Pump video too:👉 th-cam.com/video/B-hoHA46rTw/w-d-xo.html
I love the double take when you were attaching the hose. I do the same thing all the time. Awesome video. Thanks

Thanks Kayvan. You really explained in simple words and in an attractive way.👍👍👍

GOAT! Thank you. No need to get a vacuum pump! 🖤✊🏻
Can you attach a vacuum gauge to measure the pressure of the vacuum. How much vacuum are you able to develop with this vacuum pump?
Possible, but unfortunately I don't have one.

Your welcome man, I’m glad I could be helpful.
Solid 9 out of 10! Great job well done.
Thanks mate.
How is your air compressor so silent?! or are the audio levels adjusted? Thanks for the video!

good job! just keep go on 👍
Can this hurt the compressor at all? And how close to a perfect vacuum can you get compared to a dedicated vacuum pump?
It is possible to destroy your air compressor, so do it at your own risk. I never had a vacuum pump, so I cannot compare, but obviously, a vacuum pump would be far superior to a converted compressor.

Thanks Bro, I think you can find pressure gauge which shows under 1 bar pressure.
One more thing I forgot to mention is to open the tank valve so the compressor motor doesn't have to work both way.(only suction and no compression)
@@KayvanCrafted do you mean the valve underneath the tank that water drips out of? Or do you just disconnect the motor from the tank?

i dont think so, in air conditioning a constant vacvcum pump its needed and should work for long time periods
Can I use this for composite vacuum bagging

Has an none tested this?
I am not will to sacrifice my compressor to make this work if it destroys the pump long term
Are they diaphragm units?
I am not sure which part you are referring to, but the air compressor is a two cylinder oil-free unit.

Yeah, I think you mean they do this to avoid the compressor to create any air pressure inside the tank. Totally agree.
