Pressure Switches AFS-222

The AFS-222 differential pressure switches are general purpose proving switches designed for both HVAC and Energy Management applications. These pressure switches can be used to sense positive, negative, or differential air pressures. The A/AFS-222 has a field adjustable operating range of 0.07" to 12.0" W.C.. The AFS-222 has a field adjustable setpoint range of 0.05" +/- 0.02" to 12" W.C. with a field adjustable release range of 0.04" to 11.2" of W.C.. The AFS-222 will accept a 0.25" O.D. rigid metallic tubing via the integral compression ferrule and nut. The enclosure cover guards against accidental contact with the live switch terminal screws and the setpoint adjusting screw. It also contains a 1/2" conduit knockout in the cover of the enclosure.
