Homemade Silent Air Compressor using Two Refregrator Motors Compressor 

They seal so make a good storage place for oil cans ect

Great tips thanks, btw i live in tropical country

Kindly tell me does this work well and is durable enough to last at least 3 years with out coil of compressor spoling

@@kirabirarobert1920 It depends on the condition of what you start with, what you use it for, how long it is running per day.

True, the oil was supposed to be drained, and replaced. I think the oil it uses Is polyester oil Polyester Oil (POE oil) is a type of synthetic oil developed especially for refrigeration compressors. The compressors will fail after about a year or two from lack of lubrication because of what you said. Since the oil in the compressor is very little, it wont do any good as an air compressor. I know it happened to me.

👍😉

Hi you say this tank he's using was designed for much higher pressures do you know how much? And do you know how heavy it is? And when full of gas how heavy then?

@Dragomir Ronilac somebody has to be the first to try things to embark on newer knowledge. I'm just looking for a work around if I can find one

@ Don Natalie Lucas, I’ve been watching some compressed air videos, there’s a surprising lack of knowledge not only around good practice but more worryingly the devastating effects of compressed air when it goes wrong. From using propane tanks, to tyre inflation one guy is aiming for 300psi. Just hope people who are unsure what they’re doing just buy an off the shelf compressor.

@@hitop2365 I personally witnessed the aftermath of an air tank explosion over 35 years ago. Everyone was fortunate to have not been there when it happened because the amount of devastation would have easily killed us. It was also good that a vehicle wasn't in the shop because the damage would have cost thousands of dollars to repair. A portable air compressor (I think it was a 30 gallon tank) that was rated to operate at 150psi had a sticking shut off switch that wouldn't shut off until around 175psi. It also was an older unit that had been placed under the corner of a farm shop bench made of rough cut 2x8 wood. It had not been pulled to be drained regularly & would only get drained when there was a significant amount of water coming out of the hose. We would unplug it when not in use, so the nobody worried about changing the cut off valve immediately. It was slated to the "next trip to town" status. One night we had forgotten to unplug it after working in the shop. About midnight there was an explosion loud & violent enough to be felt in the house about 100 yards away. When we got t the shop, there was a corner of the concrete block building blown out about from ground level to the 4-5 foot high mark & around 10 feet down the wall. Pieces of the boards from the bench were strewn about as well as parts of the 3 layers of 2" thick wood from the edge of the sliding door. Inside there were parts of the air tank blown into the ceiling, the door, the opposite side wall 30" away, & into the 14ga toolbox in the opposite side corner. Looking at the parts showed that the tank was pitted in the lower 1/4 level. We knew the cut oof device was defective but had not even thought about the safety pop off, which was found & was stuck shut. The motor was located nearly halfway to the house & the compressor unit was obliterated. We learned several valuable lessons that day. The best were that the tank MUST be drained EVERY day, to periodically check the pop off, & replace the cut off device IMMEDIATELY when it is defective.

Fan not required. 🙂

Some fridge compressors have oil coolers

those fan expose also not safety at all, should at least make a cover

Nah mate, you're wrong about the cooling part. The air that gets compressed releases a lot of heat into the compressors. The fan is useful for cooling them down. In a fridge there's usually a plastic cover on top of the compressor. That's where the water that condenses in the fridge runs off to. When the water heats up from sitting on top of the hot compressor is evaporates and cools the compressor. So the fan is actually a very good idea.

These compressors are designed so that the stator is cooled by the refrigerant returning from the evaporator. The fan is to cool the exchanger or condenser, helping the thermodynamic cooling cycle. So it doesn't really help much to cool the compressor motor.

Thanks !

We need review to se if if it will last.

Simple..... you put 10-40 oil in the air intake problem fixed kinda how you put oil in your air tools before you use them

@@sibosifraiscompagny , naaah. It won't. You need to add compressor oil very often. Otherwise you burn the compressor. Your system is open bro!

It’s easy enough to replace the oil with clean mineral oil and that will suffice however the moisture accumulation is still an issue however that can be solved by replacing the oil depending on the frequency of use. If output moisture is a concern regarding your air tools or for painting applications, you’d simply run the output from the compressor into a small radiator fan and then an auto draining moisture trap and lastly plumb it into the tanks. This will result in roughly 85-90% +\-less moisture in output air entering the air tank.

my dad has used a compressor like that for years with no extra lub or filters.

Thanks a lot bro 👍👍

Thanks for Nice comment

@@MrDKDIY You're nicer to me, I'd told him to keep his bike helmet on and stay safe. We live in a weakling world today.

Thanks bro thanks for nice comment and your idea💡👍

Thanks for the tips!

Thanks bro for this great comment

Thank you!

cooling the heat of both compresser

Compressors get very hot when they run for a long time. Some people weld cooling fins to these things. Dude made a professional grade system.

what is the function of a fan in your planet?

Would you know of a video explaining what you just said?

Thanks a lot 👍😉

Refrigeration compressors such as these are filled with oil and sealed when they are manufactured, so no fuether oil is needed.

Most welcome 😊

can you answer me please?

Use copper not ribber hose, jeeze

👍

You didn't see tube was cut and it went into the atmosphere lol

Not to mention, the refrigerant carries the mineral oil through the whole system constantly, so I wonder if the intake side of those compressors are even getting any oil. Maybe run a drip oiler inline with some mineral oil.

Thanks to you for your support

Fridge compressors have oil in the bottom and it comes out in a mist with the discharge air. In this setup he will have to add more oil to the compressors and drain it out of the air receiver on a regular basis. I built one of these years ago, and I added an oil separator to the compressor discharge pipe. When the separator bowl got full I just poured the contents back into the intake pipe, and that seemed to work fine. I also added a sight glass to the compressor tank so I could see if it got low.

A fridge compressor has oil in it, a wet sump system, it does not rely on the refrigerant. If you turn one upside down all the oil runs out.

@@connerlabs these two items can they be asked for at home depot? Oil separator and sight glass.

@@aicram62 I’m not in the US so can’t comment on Home Depot. Any place that sells compressed air equipment should have the oil separator. I made the sight glass myself with a piece of clear plastic tubing, 2 90 degree hose barbs, and 2 holes drilled very carefully in the compressor.

Thanks

moisture - seen some cheap tire inflator compressors spit out water. lot of water squeezed out of air. they should have dryer/drain or somesuch

Yes bro its still working wery well, so i make video for DIY compressor after 1 year working thanks for giving me your idea

@@MrDKDIY okk thank you my brother ... 👍👍

👍👍😉

Thanks my BRO 👍😊

as you said it looks like a professional but it doesn't come close to that, it's very amateurish, let's buy the parkside better than the lidl

Spasiva

Thanks

coolant is usually flowing through the radiator getting cooled/releasing the heat. I agree that an open air fan is not doing anything.

I thought it was great ! I would like to get the wiring diagrams please?

Im with you on the 'music' id rather hear the dude fart his favotrite tunes than sit thru that crap everybody seems to play on their vids.

said it took 9 min to fill

Thanks

Hvala Brate 👍😁

there is no need for the fan at all, you only need it for the condenser. it serves no purpose here.

I need 3600 psi. Any suggestions?

Yes it does

@@MrDKDIY thanks Bro!!
