The AFS-460 is a general purpose airflow proving switch designed for 24 VAC (AFS-460-137) HVAC and energy management applications where a manual reset switch with DPDT contacts is desirable. It may be used to sense positive, negative, or differential air pressure. The plated housing contains a diaphragm, a calibration spring, a snap-acting switch with manual reset button, and a DPDT relay. The sample connections located on each side of the diaphragm accept 0.25 in OD 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 in conduit connection. The manual reset button is located on the top surface of the enclosure cover.

  • Multi-purpose - sense positive, negative or differential air pressure
  • Durable - housed in a plated enclosure with removable metal guard protecting setpoint screw and snap action switch terminals
  • Enclosure cover - avoid accidental contact with the live switch
  • Air or combustion by-products that will not degrade silicone sample media
  • Diaphragm in any vertical plane mounting position
  • 2 form-C rated 8 A at 250 VAC contacts
  • Ferrule and nut compression type connectors will accept 0.25 in OD rigid tubing sample line connections
