compressor information needed

New here. Please disregard the vehicle information. I am not dealing with a specific vehicle.
I need to know several things.
1: What small compressor would you consider to be best with consideration to size, weight and volumetric efficiency?
2: Can such a compressor be run without benefit of refrigerant and oil flowing through it? In other words, can the compressor be run as just an air pump?
3: Are there figures available that cover generated air volume at given RPMs and practical compression pressure limits?
Thanks, Jack

You're limited to models if you want to use a compressor as an air pump. The one that comes to mind is the York/Tecumseh type beacuse they have a sump that holds oil. They do use a moderate amount of engine HP. We used to see them on diesel engines. You need oil for lubrication.

The problem will be the compressor would eventually become empty of oil as it will be pumped out. If this is for constant use, the compressor wont last long. I agree with using ones that have an Oil sump, as they can hold much more oil.
For outputs, I'm sure there should be some tech data available. What is your application?

Thanks for the replies. I am presently working on figures for volume and pressure needs.
Will get back to you soon.

Interesting handle, "jackscars", makes me thinking about changing mine to workingonanddrivingcarscars.
Do make air compressors for suspension and air brake vehicular applications. Have a small portable Coleman that outputs as much as 150 psi and about 0.5 cpm. Better ones are use for air suspension systems, but if you can't find what you are looking for, you make one.
This question comes up frequently, like using a refrigerant compressor for air, or an old refrigerator type compressor for a vacuum pump. In principle, about the same, but the lubrication is sure different.
