Drain traps and ancillaries

Compressed air drain traps and ancillaries are used to remove liquid from pressurised air and gas systems while helping prevent unnecessary gas loss. This is important because condensate can accumulate in receivers, separators, risers, downfeeds and other low points, reducing air quality and damaging downstream pneumatic equipment. Float-operated liquid drain traps respond automatically to changing load and pressure so condensate can be discharged continuously without backing up in the line. Key selection factors include differential pressure, system pressure, condensate load, liquid specific gravity and whether return-line backpressure or flashing could affect drainage. Spirax Sarco drain trap ranges support compressed air and wider gas-system duties where reliable liquid removal is a plant reliability issue rather than a minor accessory choice.
