I stared fixing when I was 6 and never stopped,I'm an old man. I still repurpos things. Never be without a junk pile!

I been busting a** welding the plates for the other side. And in between the welding, been designing the drive sprockets, and brakes. Got the brake hubs made, got some metal from work to make the rotors, then make the calipers. Got 4 of those to make. Seen a design on utube for it using STEEL tubing for the calipers. I'll be making a video soon on how I designed the drive sprockets. Plus all the stuff around the house. Oh boy. That was pretty cool you got it through the house.

The motor mounting plate from the small refrigerator will cut away easily with that grinder and then, with a couple of drilled holes, you have an engineered mounting plate for the motor that bolts right onto your tank. Takes 1 minute.

I took my compressor and attached a fluid collection container to the intake (vacuum) side and use it to bleed brakes. It worked great. Not sure if it would work as a vacuum pump to charge air conditioning systems, want to try that next but I do agree the the quietness is a huge advantage.

great job!

That's cool, You can also use two compressors on one tank, Those are great for Air Brush guys, sometimes they are working inside and don't wanna make a lot of noise.. Some larger fridge compressors have multiple pistons.

very interesting idea, thank you!

nice wood working : ) thanks for sharing

Id say it works pretty dang good!! Looks like you are running at least 3.5-4.0 SCFM continuous pressure!! Which is a lot better then many compressors, especially for the money spent!! Think I am going to build myself one now as well. Thanks 4 sharing bud. DEv

No, it cant put out that much constantly, I have to build up the pressure in the extra tanks to be able to use the spray gun for any useful amount of time. It would work better for a airbrush setup. Thanks for watching

Hi, this is an interesting remodelling work you demonstrated. Thank you. My requirement is other way around. Want to know if I can use an existing Air compressor and tap one line to use for industrial refrigeration and other line for general air compression purpose? Basically want to use one compressor for dual purpose.

Man you sound cool and down to earth. - Rare on youtube.

@Aceman307 i built one with a 50 liter tank i use often with 2 motors on it and it takes maybe 5 minutes to fill to 8 bar ! i used hoses and normal things from around the house to build it , maybe its the lines that are the reason for it to build pressure that slow !

Nice work! The problem may be that you have too much tank for the compressor. There is a ratio of tank size to compressor output. A solenoid valve to the second tank might speed pressure build.

Any idea what the best kind of oil to use when converted to a air compressor? Probably doesn't matter, I just used the oil that came in it. The oil mist in the compressor gets sucked into the piston & cylinder lubricating the piston etc. In a refrigeration system the oil in the Freon just gets returned to the oil sump. When used as an air compressor the oil is lost in the discharge air a little bit at a time. I used a water trap on the air output to catch the oil. When Mounted at the air output of the compressor the air is still too hot to condense the water letting just the oil accumulate. I used a capillary tube (salvaged from a residential a/c unit evaporator coil) from the "water filter" drain and routed back to the air intake of the compressor returning any oil captured from the discharge back to the oil sump. The air lost through the cap tube is too insignificant to even be noticed. The lost oil is the major reason for failure of this type of air compressor conversions. The other is overheating because the compressor is designed to be cooled by the circulating Freon. I put a fan blowing on the compressor. No problem if it doesn't have to run too long. Finally bought a regular air compressor and used the refrigerator compressor as a vacuum / scavenge pump to recover Freon from old units and pull a vacuum on systems I am working on. Always wanted to but never did figure a good way to put a dipstick on the compressor to check the oil level in the sump and top it off as needed.

thank u for sharing this nice video .. this is what i need to do use 2 tank :)

You should've used the bracket from the small fridge. Just cut it a couple inches from the mounting holes then bolt that bracket to the tank. That would've made it leveled.

This type of compressor works for me, since I'm working with airbrushing, yeah it take for a compressor around 10 minutes to compress the air, bit it is worth it, cause it is insanely silent, and power efficient.

@Aceman307

8 жыл бұрын

+Guntars Lācītis Give it a try. I think it would work great for airbrushing.

Kind of neat. The only downside other than the fact that it's super slow is the fact that when used in it's designed application, the compressor actually gets cooled down by the cold refrigerant vapor coming back out of the evaporator. You no longer have this cooling gas going into your compressor, and are much more likely to trip off on the thermal overload. I think the only reason it didn't overheat is because of relatively low pressure on the discharge side vs what it would see in a refrigeration application. Anyway, cool project. Just make sure you hook an filter in line with your spray gun since the compressor will also shoot out tiny amounts of oil with the compressed air. Might want to find a way to check the oil level from time to time just to make sure you still have enough for proper lubrication.

Cool thanks! What's the max pressure a tank like that can handle (is 150psi safe)? How can you make it more powerful so it will fill faster (maybe some kind of booster circuit for higher voltage)?

THANKS VERY HELPFULL

It appears the tank check valve was removed during the build... does the compressor start and stop ok with pressure on it? Or do you need the check valve/unloader valve to be operational?

Your right, they make great airbrush compressors. It's a good idea to have an oil trap of some kind to drip back to the pump and keep the air clean.

You can't know if the fridge compressor still works well, unless you test it. The most common test would be does the fridge get cold, but that means it still had refrigerant (didn't all leak out) which means you just released all that refrigerant into the atmosphere when you cut it out? Fortunately there are much quieter small/oil-less compressors available today. Check out California Air Tools and a couple other brands whose names escape me at the moment, one of which is at Harbor Freight.

I like the idea of plumbing multiple compressors together. The only problem with that, tho, is amperage draw. When these fridge compressors start, they draw a large spike of current-up to 10 amps each or even more. For one compressor, that would be no problem -- maybe two with no problem, but more than that and you'd have to connect them to different electrical circuits. Perhaps that could be resolved with an inline capacitor between the compressor and the power source?

Capacitors only really have that effect on DC - on AC, it just draws more power. Time-delay relays so they fired up sequentially would work, though. For a larger compressor, you could use an aircon one.

I have seen some people use 2 or 3 compressors to get the air volume needed, it could be something to look into.

You can easily kill a small compressor by running it for long periods of time. If the oil goes over 100C it will cook, degrade and coke up the reed valves. Take a look at the spec of a commercial silent compressor (bambi etc) for a idea of duty cycle.

rafi saifuddin If you want quiet, fractional HP fridge compressor. If you want power and speed and are ok with having a hefty compressor, A/C. Make sure you have someone collect the refrigerant legally as it is a greenhouse gas and you could be charged $37,500 (max). It's easy enough to hand a 20 to an AC guy to have him recover the refrigerant. ACs are usually also more expensive and harder to get ahold of. But you can get 1.5-5 HP compressors easily from an AC but they're usually also 230V. The larger ones will make more heat and all compressors should be kept cool at least a bit. Cooling is normally done by cool returning refrigerant.

I wouldn't use a appliance compressor for painting. They output oil that can leave droplets and marks in paint. I built a 3 gallon silent compressor using a dehumidifier compressor, if you don't feed it oil it might burn up but it also outputs that oil. And make sure to not tip them upside down, or all the pump oil will leak out!

The oil is not seperate, the intake to the piston is inside the compressor shell. If you use the original oil it`ll pick up moisture and foam up..foamy oil isnt good for lubrication. Using a large tank (let alone two tanks) with a small compressor is not a good plan. You dont want the oil to get above 100 deg C as it`ll turn acidic and attack the copper windings of the motor. Commercial silent compressors typically have a duty cycle of 50% for this very reason.

The speed is about 3000 rpm in most compressors.The size of the a/c piston is larger ( displacement) and the motor is larger in the a/c unit so the a/c unit moves more refrigerant. having said that ,,,,, the industry has for quite some time switched from piston ( reciprocating ) to scroll compressors ( non piston). The newer compressors (scroll) HATE heat . Cannot be used as a air compressor.

I used to know a guy in Fla., that did the same thing only using a commercial compressor and an old 500 gal propane tank. Unbelievable. This thing put out over 300 psi and I can't remember the cfm, but it was very high. In fact unless we were using the 1" impact gun on the semi's, we'd have to drop down the psi and cfm using regulators. It ran an entire shop including several lifts & a paint booth for over 25 yrs with minimal maintenance. Once the pressure dropped (which took several hr's) the compressor would kick in (we could still use the smaller air tools) and it'd take approx., 15-25 minutes to reach full pressure again._

how come the video is of latin origin and your voice doesn'tt match the individual in the video? you didn't even put up the tech spec, what is max psi output of compressor, what size valves you used/purchased.

that compressor wont last long because it uses the refrigerant to cool the motor windings and the poe oil will break down fast because water attracts to poe. but I was curious to see someone do it lol. good job!

Thanks for the thought. But........ it is wrong to do this. If you understand the compressor operation and design in the refrigeration a/c cycle. The refrigerant coming back from the evaporator ( freezer section ) cools the windings so the compressor and the motor windings and the oil in the compressor stay below 300 deg Fahrenheit . The piston will not have rings , so oil is designed to pass to the discharge side into the refrigerated system to later be brought back to the compressor. These style compressor are designed to start with equal pressure on the high side and low side. Hence came the comment do not start and stop the a/c or refrigeration system rapidly. When ever you shut off the unit wait 5 minutes to restart the compressor. If you want to use a refrigeration compressor , get hold of a open drive compressor, remembering these pistons on the small compressors do not have rings to keep the oil in the compressor. ( these compressors are hard to find now) The compressors that are designed to be restarted soon after have some sort of a hard start kit wired into the electrical motor. To connect these or any of the refrigeration ( tin cans) compressor in parallel is a waste of operating $$$$$$. Keep trying , A lot of bad ideas wind up turning into some great inventions, so don't give up trying to come up with something new.

I really enjoy plans from woodprix.

Seems like the loss of oil in the compressor would become a problem

An hour to fill the tank.WTF!!! no thank you... my compressor takes 2 minutes... it would be good for blowing up balloons...
