Cleveland Controls AFS-145-112 Air Pressure Switch 0.05-12" WC is a safety and control part that measures the change of air pressure and changes a single-pole double-throw contact when the preset values are surpassed. This switch goes inline with the tubing at designated pressure points to enable the use of fans in a dotted sequence, and safety interlocks are applied. In HVAC systems, it assists in pressure monitoring and control of keeping the correct airflow conditions in the compatible forced-air system and ventilation system.
