FISHER 67DFR-22 is a direct-operated pneumatic filter-regulator designed for low-pressure instrument air and gas control applications. Manufactured by Emerson, this compact unit combines filtration and pressure reduction functions in a single aluminum body, ideal for supplying clean, regulated air to pilot-operated controllers and pneumatic instrumentation.
The 67DFR-22 features a C2 spring configuration providing an outlet pressure range of 0-20 psig, suitable for low-pressure control requirements. It includes a built-in 40-micron filter element that removes particulate contaminants from the gas stream, protecting downstream equipment and ensuring reliable operation. The regulator has a maximum inlet pressure of 250 psig (17.2 bar) with a 1/2 NPT body connection.
