Description
The ICP 1170927 Vent Air Pressure Switch is a control part to monitor airflow and venting conditions within HVAC systems such as furnaces and packaged heating units. It operates by sensing differential air pressure through a diaphragm that responds to changes in blower airflow, activating or deactivating electrical contacts when preset limits are reached. It is installed in the venting or combustion air circuit using tubing connections that link to pressure points within the system. This component ensures a safe ignition sequence, supports proper exhaust flow verification, and supports maintaining the system.
