Description
The Cleveland Controls AFS-298-112-148 SPDT Static Air Pressure Sensing Switch Rise is a unique part that is used in HVAC systems to detect and regulate the flow of air. It serves as a static air pressure sensing switch, using a single pole, double throw switch operation. This switch is intended to work under a definite pressure range of 0.45 to 0.05 inches of water column. This part operates based on the variation in static air pressure in the HVAC system in which it is installed. The SPDT switch turns on powering an electrical signal. This signal can then be used to control various HVAC components for instance dampers, fans, or alarms to improve the performance and efficiency of the system.
