Description
The Cleveland Controls AFS-222-GRY-I Differential Pressure Switch is a high-quality that is used to control and measure airflow in different HVAC systems. This switch functions in a pressure range of 0.1” to 4” water column and hence can be used in many applications. Instead, it operates based on an intermittent measurement of the pressure differential across a filter or other resistance to airflow in the HVAC. If the pressure differential rises beyond a pre-set high limit, the switch triggers an alarm or sends a control signal to suggest the possibility of a filter clog or any other problem affecting the airflow.
