Adjustable Setpoint Differential Pressure Switches

Model AFS-22 Differential Pressure Switches are general purpose proving switches designed for HVAC and energy management applications. It may be used to sense positive, negative or differential air pressure.

The plated housing contains a diaphragm, a calibration spring and a snap acting switch. The sample connections on each side of the diaphragm accept 0.25" O.D. metallic tubing via the integral compression ferrule and nut.

An enclosure cover guards against accidental contact with the live switch terminal screws and the set point adjusting screw. The enclosure cover will accept a 0.5" conduit connection.
