Description
The Cleveland Controls AFS-288-112 Air Flow Switch monitors airflow conditions and activates electrical contacts when the required air pressure differential is reached within the system. It operates through a diaphragm sensing mechanism that responds to changes in air movement, allowing accurate airflow verification in HVAC systems such as furnaces, air handlers, and ventilation equipment. Built into the control circuit, it works alongside blowers and draft systems to confirm proper airflow before equipment operation continues. It support safe system sequencing, reduces the risk of improper airflow conditions, and contributes to equipment performance.
