Description
Cleveland Controls NS2-0307-00 Air Flow Switch is used to check the flows in heating and ventilation elements like furnaces, air handlers and ventilation HVAC systems. The switch is connected to the air pressure sensing port or duct tubing, and the flow of air results in an internal diaphragm that alters the state of electrical contacts. It ensures that the control circuit confirms the blower or inducer fan operates efficiently to provide sufficient airflow before heating or ventilation can proceed. It aids the safe operation of equipment, secures the parts of the system.
