a/c compressor for air bags

I am wanting to use an a/c compressor off my motor to run my bags, ive done this on my old toyota and things but i am wondering on what to do about an oiler, i have never put one on or had one on mine, therefore i have went through some compressors, so my question is how and what to use. any suggestions would be awesome. The a/c compressor i am using is off an LT1 if yall are wanting to know, thanks a lot everyone.

I used a inline oiler for a air com. I cant remember where i got it though.
