Description
The Cleveland Controls DFS-448-452 Air Pressure Sensing Switch used to monitor slight variations of pressure within HVAC systems. This switch works at a specific pressure of 0.05”WC with a variation of + 0.025/- 0.005” W.C and measures airflow while initiating actions on the basis of pressure variations. It is often installed in heating ventilation unit equipment that includes air handlers, VAV box, and duct systems, it provides the right air distribution and balancing, as well as helps regulate ventilation as required to offer energy efficiency.
