Rotary Screw Compressors

So you're looking for an air compressor that's compact, runs smoothly with low vibration? A rotary screw compressor may be everything your looking for!

Rotary screw compressors work by using two screws to compress the air into the tank. The air moves through the intake and is pushed through the threads as they spin being compressed and exiting a the other side of the screws.

What makes this type of air compressor so efficient is having such a small gap between the threads. This basically seals the air in
and allows for a tight pressure where an oil flooded screw compressor completely closes the gaps between the screws offering a hydraulic seal.

Rotary screw compressors are usually compact and run with limited vibration. Although they don't require full suspension mounting, elastomer vibration isolating mounts are used to absorb higher frequency vibrations.

Screw compressors are generally used for industrial applications and often because of the low noise and smooth running they are mounted on trailers for mobile use.

Because an oil free screw compressor doesn't have such a tight seal, it offers a slightly lower maximum output pressure.

Oil flooded screw compressors offer a higher maximum output because of the tighter hydraulic seal.

The main benefits of going with a rotary screw compressor are:

Reduced Maintenance - The main moving parts of a screw compressor are the screws/rotors. There are no vales, pistons, rings or connecting rods that require regular maintenance.
High Compression Ratios
Suitable for Various Uses - It takes very little or no changes to the unit to vary it's uses.
Small Sizes - A rotary screw compressor takes up minimal space compared to traditional piston units.
Low Noise and Vibration - Because screw compressors have less moving parts, they are quieter and vibrate much less.
