Watts FluidAir F504-01AHX11 Miniature Filter

The Watts FluidAir F504-01AHX11 Miniature Filter is a 1/8 in NPT compressed air filter that removes water, dirt, rust, scale, and particulates from pneumatic systems while maintaining high airflow and a low pressure drop. Part of the F504 series, it uses a 20 micron filter element and a polycarbonate bowl (1 oz) housed in aluminum with a manual drain for inline installation in compressed air preparation systems. It tolerates up to 150 psi inlet pressure and supports up to 22 SCFM of flow, operating safely up to 125°F (52°C). The unit is designed for use in automation equipment, manufacturing facilities, assembly lines, packaging machinery, instrumentation systems, air-operated tools, process control panels, material handling equipment, HVAC controls, OEM equipment, and other industrial production environments, and is commonly applied in pneumatic control panels and preventive maintenance or new installations by system integrators. The F504-01AHX11 variant is the X11 option (no internal parts). Replacement parts include Watts FluidAir F504-01AH, F504-01AHS, and F504-01DH. Its deflector design creates a swirling airflow pattern to enhance moisture and dirt separation, helping protect valves, cylinders, actuators, regulators, and other sensitive control components from contamination and premature wear. Manufactured in the USA.
