Description

This professional-grade flow switch, also known as an air pressure or air proving switch, is a critical safety sensor used in a variety of heating and ventilation appliances. It is designed to detect the presence of adequate airflow within the system, ensuring that the blower motor is functional before the heating element or burner is activated. This prevents hazardous conditions such as overheating or the buildup of unvented gases. Built for reliability and precise switching, this component is a standard replacement part for residential and commercial HVAC maintenance, helping to restore efficiency and safety to your equipment.
