 The screw compressor unit, also referred to as an oil-free low pressure screw compressor airend or “helical screw” compressor, operates through rotary motion. It delivers a constant flow and variable pressure, independent of speed, thanks to its helical profile rotors housed within a casing.


These rotors, one male with 3 convex lobes and one female with 5 concave lobes, rotate in opposite directions, creating working chambers that compress air as it moves from the intake to the compression side. The screw compressor unit offers advantages such as steady, non-pulsating airflow, minimal maintenance, and extended lifespan due to precise tolerances and an oil-free design.
