Product Details

Description

This premium HVAC air pressure switch is an essential safety component designed to monitor and prove airflow within forced-air heating and cooling systems. As a critical air proving switch, it utilizes a Single Pole Single Throw (SPST) contact configuration to verify that the draft inducer motor is functioning correctly and that the venting system is clear of obstructions. Rated for 28VA pilot duty, this control ensures the appliance only proceeds with the ignition sequence once safe operating conditions are met. It is a common replacement part for gas-electric units and rooftop systems where reliable air pressure sensing is required to prevent hazardous operating conditions and ensure optimal furnace efficiency.
