whats better : a/c pump or air zeniths

i guess what i ment by that was a non piston pump but a screw/scroll type compressor.

The scroll styles that I have seen are still lubricated with the freon like most compressors.

I am not aware of a 'screw' type a/c compressor but if anyone knows of one, please let us know. I think a screw style would be the answer to all the oiling problems because the oil could be self contained just like most superchargers. They don't blow oil and they dont use oil...provided there are working properly.

Mr. Max Fish has spoken, listen to him and your problems are solved! and thats no joke!

i run an a/c comp. from an older ford, i forgot which year but i picked it up from autozone for a 100 bucks

Those are the ones that are square right? Those are internally lubricated and shouldn't pump oil into the lines. Unfortunately they are combersome and tough to find a home for under the hood of a mini, but they are the best answer.

Anyone know what trucks the Ford ones came off of? I'd love to pull off my smog pump...

Your all talking bout these early ford pumps, whats early mean? What years we talkin here???

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.

the fords ran Yorks, the most common is the mini york model 209. people also run the 210. the 209 is most likely what youre buying from autozone, found on something like a late model F-100, like '79 or something. heres one i found real quick. note youll have to buy a clutch as well.

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.
