AFS
Dierential Pressure Switches (Metal)
The AFS Series Dierential 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 dierential air pressures when used in conjunction with an A/SPT
or A/VPT Series sampling tube. The plated housing contains a diaphragm, calibration spring
and single snap-acting contact closure with either a manual or automatic reset switch
depending on the model. The enclosure cover contains a ½” conduit knockout and guards
against accidental contact with the live switch terminal screws as well as the set point
adjusting screw.
Applications: Monitoring Filter Blockage, Proof of Flow, Prove Excessive or Insucient Flow, Alarms and Control
