A.J. Antunes 8221212022 Differential Pressure Switch 0.05"-9" WC Compressor Fitting

The A.J. Antunes 8221212022 Differential Pressure Switch is used to measure pressure variations in HVAC systems. Working on the concept of pressure differential across elements such as filters or dampers, it sounds an alarm or sends a control signal when the pressure differential rises beyond the set limit. This 0.05-9” WC switch with a compression fitting is easy to install and is used in different HVAC accessories like air filters, fan coils, and VAV boxes. Some advantages of using this switch may include; system efficiency because the airflow is always checked and maintained, reduction in the maintenance by checking whether the filters need replacement or not and safety from blocked airflow.
