Description
The Cleveland Controls AFS-222-136 Air Pressure Switch is a sensing component designed to monitor changes in air pressure within ducted airflow and combustion air systems. It detects differential pressure levels and activates or deactivates connected control circuits when preset conditions are reached. In HVAC systems, it is commonly used in furnaces, air handling units, and ventilation equipment to confirm adequate airflow before system operation continues. The switch acts as a safety and control component that responds to airflow variation, assisting in proper system sequencing and stable operational performance.
