An air pressure switch is a safety and control component used in industrial burners and combustion systems. It detects the presence of adequate combustion air pressure and signals the control system to allow burner operation.
The switch typically works by sensing differential air pressure generated by the combustion air fan or blower. If airflow drops below the set threshold, the switch interrupts the burner sequence to prevent unsafe combustion conditions.
Air pressure switches are widely used in industrial boilers, furnaces, ovens, and thermal processing systems. They provide a reliable safety interlock that helps maintain proper air-fuel ratios and protects equipment from combustion failures.
