Ac to onboard air conversion
- Thread starter slyguy_22

The rotary type compressors GM used require external lubrication, i.e. you gotta have an oiler, then a dryer, and either keep the oiler refilled or recycle the dryer into the oiler. Otherwise they blow up fairly quick. AMWIKT / BTDT.
The Yorks are internally lubed, so they're much easier to plumb, which is why they are so often used.

The older radial (log) compressors have an oil chamber in them. I've only been running mine as air for a couple months, a local friend has run his for 6+ years without issue. No in line oiler or anything.
Not sure i follow the "log" what do you mean? is there certain years these were found on? also if they are externally oiled, how come ac still works? i dont see any oiler on it now? the ac compressor is the original one off my 89 blazer that is on my truck now. but i dont use the ac at all so i figured there must be a way to convert it. even if i have to add an oiler it wouldnt matter to me. i could hook it to a master switch and only run it when i need it? maybe im not thinkin the right way but it seems that with a switch that it wouldnt run hardly ever, only when i wana use it. figured i could do a switch in the cab with a pressure switch then to the compressor. if i added an oiler, which one should i use? couldnt i run a line from the air/oil seperator back to the oiler and just have to top it off once and a while? sorry for so many questions, but i wana put this together this weekend.
So out of all the big wheelers here no one has done this conversion? guess ill doit and let you know how it goes
People do it all the time with York AC compressors. They are found in all sorts of cars and trucks just not ours. There is a really good write up in the tech section

What they are saying is that the added cost of the oiler to put the oil into the air compressor then a separator to remove the oil from the compressed air isn't worth the cost, when you can pick up a York from a junkyard for cheap. The compressor that is in your 89 uses oil that is carried with the refrigerant, so to use it for the compressor you have to find a way to add oil to the incoming air, then remove the oil. Yes your switch would prevent it from running by disengaging the clutch, but when it is running the oil is problematic. This is where the York is superior since it has an internal oil supply that is not part of the air supply. No need to add air to the supply air or remove it from the compressed air.
not to mention iirc, the York puts out WAY more air than the GM can...

Oooops I forgot to mention that as well. The large bore York is a huge amount of air over the stock GM compressor.
ok so what vehicles have them and can it be mounted in the stock location for my ac?
Does NOBODY ever read the tech articles? Never mind using search

this is what I use oasis manufacturing. A bit spendy, but it will run air tools all day.0 to 200 psi. in 33sec.
