Description
The Cleveland Controls DFSH-CO Fixed Set Point Pressure Switch that is used in HVAC systems. This switch measures the pressure of air in ducts of HVAC equipment. At the pressure value of 0.4”WC, the switch turns on an electrical circuit to indicate a change in system status. It is widely applied for proving the required air flow in ventilation systems, checking that the fans work properly, or to identify filter obstruction. Advantages are accurate airflow measurement, equipment protection from possible damage due to low airflow, and proper system functioning. This is most commonly used in air-handlers, rooftop systems and other HVAC applications where close pressure control is required.
