Oil Flooded Rotary Screw Compressors are largely supplied by two companies from Air and Gas Technologies. Sullivan Palatek and Chicago Pneumatic are the lines that we've chosen to work with. We have the experience and relationships to provide the highest quality of service for these machines.

The Oil Flooded Rotary Screw are the best compressors proven by the test of time. These units function cooler and quieter than comparative piston reciprocating compressors. If you're looking for a quality rotary screw air compressor for sale, you'll find them here. If you don't see the horsepower and SCFM you need online, we can get it for you.

We offer small rotary air compressors from 5-15HP all the way up to 300HP massive rotary screws and VFDs

If you need a rotary screw air compressor with dryer, we can also provide the ancillary systems to ensure that your air system works perfectly with your designs and specifications.

What is the rotary screw compressor?

The Rotary Screw Compressor is a unit with two large helix shaped components. They are spun rapidly by an electric motor. Since they can be a direct drive, this allows for them to be run at variable speeds, allowing various amounts of electricity to be used and also allows VFD trimming on larger air systems.

This type of unit can be oil-free or oil-flooded. It is possible for them to be oil free by coating the helix screws with a special compound which allows the teeth of the screw to mesh with less friction than normal

How does the rotary screw compressor work?

The air ends of the helix screw draw in air and force them through the narrowing portion of the spinning screws pushing compressed air at some ratio out the other end of the screws. This is the main working principle behind the rotary screw
