Clarke 3120514 CAT197 1/2" Standard Airline Filter/Pressure Regulator with Gauge

Designed to remove airborne impurities, dirt particles, condensation and oil aerosols from compressed air through air supply lines and also maintain air pressure at a set level that can efficiently operate air tools and other air operated equipment.
The filter works by means of centrifugal force with a filter element while the regulator is self-relieving and provides high air flow while maintaining the set pressure with minimal pressure drop.
