Cleveland Controls DFS-221-112 Switch allowing for precise tracking onThe Cleveland Controls DFS 221 112 Switch is a fixed setpoint air pressure sensing switch designed for critical airflow proving in duct heaters, ovens, and energy management systems. This SPDT airflow switch is factory calibrated to actuate on a pressure rise at 0. 05" WC ( 0. 02" WC), making it an ideal solution for applications requiring a non adjustable, tamper proof safety interlock. Built with a durable silicone diaphragm and a zinc plated steel
