Ensure your HVAC system operates safely and efficiently with this high-quality Dual Air Pressure Switch. Designed as a critical safety and performance component, this air proving switch monitors atmospheric pressure changes within your heating and cooling equipment to verify proper airflow. It features two distinct set points—0.50" WC and 0.17" WC—to ensure that the blower motor or inducer fan is operating within correct parameters before allowing the system to proceed with its cycle. This dual-stage functionality provides an added layer of protection, preventing the system from running under unsafe venting conditions or insufficient air movement. Ideal for professional HVAC repairs and maintenance, this durable sensor is essential for maintaining system reliability and equipment longevity.
