Cleveland Controls DDP-106 SPDT Air Flow Switch 0.07-2.0" WC

The Cleveland Controls DDP-106 SPDT Air Flow Switch used to detect air flow in HVAC systems. It measures changes in air pressure due to fan operation or airflow obstruction within a pressure range of 0.07-2.0” WC. When airflow gets to a certain level, the switch turns on or off or sounds an alarm to the system. Installed in air handling units, furnaces, and ventilation systems, it maintains the right airflow for heating, cooling, and ventilating. Advantages include increased system efficiency, protection of equipment from operation where there is insufficient airflow, and safety, where blockages to airflow are detected.
