Rotary Screw Compressors
A rotary screw compressor uses two intermeshed helical rotors (screws) within a precisely machined stator to compress air. Clearances between the rotors and the stator are very small and are usually sealed by injected lubricant. As the rotors turn, their helical grooves trap air and seal against the stator wall. The volume of these grooves decreases as the rotors turn and mesh together, compressing the air while moving it to discharge port.
Rotary screw compressors are built as packages which consist of the compressor unit (air end), lubrication system, cooling system, capacity control system, and discharge air cleanup system.
