Wells 2E-Z21020 Pressure Switch Filter

The Wells 2E-Z21020 Pressure Switch Filter is a filtration component used with compatible pressure-switch assemblies. Installed in the designated pressure-sensing circuit, the filter restricts debris or contaminants from reaching the pressure switch while allowing the required pressure signal to pass through the connected system. This protects the sensing passage and supports consistent pressure detection during equipment operation. The filter interfaces with the pressure line and switch assembly and forms part of the equipment's pressure-control circuit. Its placement allows it to be serviced when contamination affects the pressure path or when maintenance of the associated pressure-switch system is required.
