Product Details

Description

This premium air pressure switch is a vital safety component for residential and commercial HVAC systems, specifically designed for gas furnaces and high-efficiency heating units. Often referred to as an air proving switch, its primary function is to monitor the pressure differential created by the draft inducer motor. By ensuring that combustion gases are being safely and effectively vented out of the heat exchanger, this switch prevents the system from igniting under unsafe conditions. If your furnace is failing to start or is shutting down during the ignition sequence, a malfunctioning pressure switch is a common cause. This component features precise factory-set water column (WC) trip points to ensure your equipment operates at peak safety and efficiency levels.
