Description
Cleveland Controls DDP-106-256 Dual Switch Air Flow Switch that is used in HVAC systems. It operates based on the control of differential air pressure which selectively opens or closes electrical contacts in order to indicate presence or absence of airflow. This functionality is essential in HVAC equipment such as air handlers and duct work to avoid problems such as coil freeze up. Advantages of this switch include increased system effectiveness, better comfort for the occupants due to steady airflow, less energy use due to proper control of the fan, and better system performance since equipment damage due to airflow problems is avoided.
