Wilkerson M28-04-BL00B Coalescing Filter 1/2 in Port

Product Description

The WILKERSON M28-04-BL00B is a coalescing filter designed to remove liquid aerosols, oil mist, and fine particulate from compressed air lines. It fits into pneumatic systems where clean, dry air is critical to downstream equipment performance and service life. The 1/2 inch port size suits mid-range compressed air distribution lines commonly found in industrial and commercial service environments. An integrated sight glass allows technicians to monitor bowl contents without disassembly. HVAC, pneumatic controls, and general industrial maintenance technicians install this unit as part of air preparation assemblies.

This filter is suited for compressed air treatment applications in industrial facilities, commercial buildings, and mechanical rooms where pneumatic tools, actuators, or control systems require oil-free, moisture-reduced air. The 1/2 inch port makes it a practical fit for moderate-flow distribution headers and branch lines. It functions as a standalone coalescing stage or as part of a multi-stage filter-regulator-lubricator assembly.
