This FRL Combo is designed to filter and clean compressed air inline with the Samson Pumpmaster series pumps. It will strain the air and trap solid particles of dust, dirt, etc. and separates liquids (water, oil) entrained in the compressed air.
Filters are installed in the air line upstream of regulators, lubricators, directional control valves, and air driven devices such as cylinders and air motors. Threaded to fit 1/4" threads.
