Centrifugal SeparatorsCentrifugal separators also called water separators and mechanical separators use centrifugal motion to force liquid water out of compressed air. The spinning causes the condensate to join together on the centrifugal separators walls when the condensate gains enough mass it falls to the bottom of the separators bowl where it pools in the sump until it is flushed out of the system by the automatic float drain valve.

It is important to remove condensate because it corrodes exposed metal components throughout the system sometimes destroying expensive equipment. Centrifugal water separators are installed downstream of aftercoolers, air receivers, and refrigerated dryers. Our centrifugal separator design features an internal spinner that removes large quantities of condensate by centrifugal action. Water separators are available for operating pressures up to 16 barg (232 psig).
