Wilkerson M28-04-BK00B Coalescing Filter 1/2 Port

Product Description

The WILKERSON M28-04-BK00B is a coalescing filter designed to remove oil aerosols, fine particulates, and liquid water from compressed air lines. It is installed inline in pneumatic systems where clean, dry air is critical to downstream equipment performance. The 1/2 inch port size makes it suitable for mid-range compressed air distribution lines found in industrial facilities, manufacturing operations, and HVAC control systems. This filter is installed by pipefitters, pneumatic system technicians, and HVAC controls specialists who maintain air quality in compressed air networks.

This coalescing filter is used in compressed air systems that supply pneumatic actuators, instrumentation, spray equipment, and other air-powered tools or controls requiring oil-free and particulate-free air. It is a direct replacement or addition to existing filter assemblies on 1/2 inch compressed air lines in both light industrial and commercial mechanical system applications.

Installation Notes

Installation should be performed by a qualified pipefitter or pneumatic systems technician. Depressurize and lock out the compressed air supply before removing or installing any inline filter component. Use appropriate thread sealant on threaded port connections per the system manufacturer guidelines. Verify flow direction markings on the filter body before final assembly.
