Why Use A Rotary Screw Compressor

Screw technology is a type of rotating positive displacement compressor or rotary compressor. Unlike piston air compressors, screw compressors have no valves or other oscillating mechanical forces to cause imbalances.A screw compressor can operate at high speeds while combining a large flow rate with small exterior dimensions. There are two primaryrotary screw compressor versions; oil-free and oil-injected. For each version, there are options of fixed speed or variable speed drive operation.
