i need some help understanding please!!!!!

so i just hooked up my ac comp that im trying to turn in to a edc. its a sanden 708. i need some help to understand some things. is it right that i dont need a inline oiler? also the nut on top is where the oil goes correct, what kind of oil do i put in there and how much, just till it comes out the top or what? thanx ahead of time guys.

I'm not sure the 708 is oilless, I know the 508 is. You should call an AC shop and verify that it is.

If it is, the nut in the top is for checking and adding oil and you wont need an oiler. But beware, Sanden could have used the same case as a 508 on the 708 so it may not be oil-less just from having the nut.

ALL AC COMPRESSORS NEED OIL FOR THE BERINGS TO STAY LUBRICTED USE NORMAL COMPRESSOR OIL IT IS PRETTY EASY TO FIGURE OUT WHAT GOES WHERE AS OF OUT AND IN TURN THE WHEEL TO TELL WHICH ONE PULLS AND BLOWS

not all AC compresssors are oiled dude, some come in oil-less.

and lose the caps, we can read ya loud and clear

when I say oil less, I mean that the oil is separated from the pressurized lines. Maning normally there is refrigerant AND oil in the lines, so if you convert the AC compressor to an air compressor, you have to feed oil to the inlet and remove it at the outlet.

But an oil less compressor like the york and the 508 sandens have a separate oil resevior and the air/refrigerant is pressurized DRY.

Sorry for the confusion.

lol, thanks for the clarification russ, I was about to waste a post on that....

....no wait, doh!!!

How do you get the oil out the outlet, just run a a standard air compressor dryer like you would on your shop compressor? I would imagine some sort of catch can type mechanism like that would be combersome, has anybody found a way to extract it and cycle it back through?.

I think with the trouble of lubrication and that the design for most AC compressors makes them impractical for filling a tank of compressed air I would just buy a compressor designed for what your using it for.

lol, ok so hopefull I didn't waste a post :-?

they sell inline oilers, and inline DE oilers lol.

I havent looked at the RX7 too close yet, I just drug it home today. But I know it has a sanden on it too. I think I'll switch to EDC, because 150 psi from a single Viar aint doin it.

i actually have a mazda ac compressor on my fullsize chevy for an engine driven. i took like 3 a/c compressors apart to make the serpentine belt conversion work. they are the best engine driven compressors i've seen. i had basically a trap on the outlet hose, instead of dumping it, i had a recirculation line that would redirect it back into the inlet. just hit the drain button and let it flow.

so how much pressure will a sanden 708 put out?

all automotive aircondtioning systems have oil in the refrigerant. there are NONE that run straight refrigerant.

only the York, Tecumseh and the Chrysler V-2 compressors have oil in the lower part (oilpan) of the compressor.

if you run any compressor with no oil reserve without an inline oiler, you WILL eventually burn up the compressor.

even running a York with the oil mod, if you run it too much without at least a small amount of oil in an inline oiler, you WILL burn it up as well.

using a Sanden is a waste of time and money, as it will never run forever. it will eventually burn up. if you run alot of oil into it, you can make it last a long time, but then you get oil in the tanks and even with an oil/water seperator you still get some and eventually it messes everything up.
