About Air Flow Switch (AFS)
The AFS is a general purpose airflow proving switch 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
SPDT (NC) switch.
The sample connections located on each side of the diaphragm accept a .25” OD
tubing via the integral compression 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 .5”
conduit connection. The AFS (1414-CPM10APWAB) has a reset button located on
the top surface of the enclosure cover.
