Description
The Cleveland Controls AFS-298-391 Pressure Switch is used to measure and act on the pressure in the air in HVAC systems. More specifically, this is designed for a 0.3” water column and is applied to numerous HVAC systems, such as air handlers, fan coil units, and VAV boxes. It has the significant function of measuring and regulating the flow of air in these systems. If the air pressure is high or low from the set point, the pressure switch sounds an alarm or sends control signal to change the operation of the system. This has better performance, energy conservation, and comfort for the occupants.
