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.
