Product Details

Description

Ensure your HVAC system operates safely and efficiently with this professional-grade Air Pressure Switch. Also known as an air proving switch, this essential safety component is designed to monitor the airflow and differential pressure within your heating and cooling equipment. Its primary function is to verify that the draft inducer motor is functioning correctly and moving enough air to safely support combustion or system operation. A failing pressure switch can lead to system short-cycling, ignition failure, or complete furnace shutdown. This durable replacement part is engineered to provide precise sensing and reliable performance, making it a critical fix for restoring the safety and efficiency of commercial rooftop units and industrial HVAC systems.
