One thing I have been thinking about for the past year or so is why cant we get a compressor without any oil blowby? Think about it for a second, a (in shape) car engine has almost no blowby at all I would almost say none in most cases, an EDC is just like an engine. I understand why ac comps do it but don't you guys think there is enough of a demand for a compressor with no oil loss? I would install EDCs in all my customers rides if they where low maintence, and I wouldn't see $750 or even $1000 bucks being unreasonable for an EDC that would work the way I need it to for my customers.

No Shit! we can fly to the moon but we can't make a compressor that doesn't use/blow oil. I agree, they would sell like crazy. I used my stock a/c pump and love it, but aside from the oil issue, I always worry about it dying.

Any style should be able to be built that doesn't use oil. Just as you stated a good running car engine uses oil for lubrication but does not 'use' oil. Make a compressor that does the same.

I think a screw style compressor would be the easiest and most reliable. It would eliminate the friction which requires the oil. With a screw style (supercharger style) compressor the only oil that would be needed would be self contained in the ends with the bearings. Provided everything is functioning properly, there would be no oil use.



I think the main difference is that the supercharger is pumping massive CFM at a low pressure, I'm not so sure that style compressor would work for higher pressure.

I'm not talking an actual supercharger itself. i'm not sure they would produce the pressure either. However, many commercial and industrial compressors are 'screw' style and produce massive amounts of air and pressure. I've never seen the internals of one, but I would assume it is somewhat similar to the workings of supercharger.

The scroll style compressors are also used for large a/c units and may possibly be used for a standard air compressor,i'm not sure. I just know those that I have seen used in the automotive industry still require lubrication through the freon. The concept is good if this could be eliminated.

1970 ford mustang with a 302 motor is the ac compresor i got for my ranger, its a york 210 , has bigger pistons so it puts out more air, there is a website called killbeenterprises i thnk thats how u spell it, the compressors are used for ofroad so when the trucks go up rocks they let the air out o the rockers so its easier to climb than pump it up when tey get over it

Even the yorks WILL blow oil. It might be less than an ac, but they still do it. There is a mod you can do to them that 4x4 people do. I lost the link when my computer crashed but try some searching and I'm sure you can find it. BTW I run a stock ac pump on my lincon, 14 gallons of air, 200 psi daily. Works great. Would never go back to electric.

Engine Driven is the way too go but dont waste money on some kit find a York off a ford in the junkyard and hook that bitch up on my 99 yota we just did one that kept all factory a/c and power steering... ill try to get some pics up and we'll be selling a kit to do so for this model truck too if any ones interested

and too add to my previous post i havent had oil coming theough any of my lines if your experiencing that you may have put too much oil in the pump it shouldn't do that

i havent maintenced my edc in almost a year and its on my daily driver with no problems or need for re-oiling

Yorks still blow oil. I know multiple people running them. Theres the mod I was talking about to cut back on it.
