CLEPAS Air Pressure Switch

Senses differential air pressure in HVAC systems and provides and
on/off output. A typical application is sensing fan shutdown in a
unit ventilator to close the outdoor air damper.

• Reliable pneumatic operation.

• Adjustable setpoint (switching pressure).

• Eliminates electrical interlock wiring.
