Cleveland Controls DFS-221-156 Switch this open frame transformer providesThe Cleveland Controls DFS 221 156 is a heavy duty, fixed point air pressure sensing switch engineered for precision airflow verification in HVAC, duct heater, and combustion systems. As a direct FS BO 179 cross reference, this SPDT switch is factory calibrated to actuate on a pressure rise of 0. 05" w. c. (+ 0. 02"), making it a critical safety component for proving draft in boilers and furnaces. Its open mounted design is specifically optimized for
