SPDT Air Pressure Switch Adjustable 0.02" - 12" W.C.

AFS-222-112 Air Pressure Sensing Switch is a general purpose proving switch designed for HVAC and Energy Management applications. It may be used to sense positive, negative, or differential air pressure. The AFS-222-112 is equipped with convenient barbed sample line connectors that accept flexible tubing. Set Point Range: 0.05 ± 0.02" - 12.0"W.C. Field Adjust

Please Note: To precisely calibrate a Cleveland Controls air switch, a digital manometer is recommended to confirm set point at actual operating temperature.
