Wilkerson M28-04-CK00B Coalescing Filter 1/2 Inch Port

Product Description

The WILKERSON M28-04-CK00B is a coalescing filter designed to remove oil aerosols, fine particulates, and moisture from compressed air lines. It is installed inline on compressed air systems where downstream equipment requires clean, dry air free of lubricant contamination. The unit uses a 1/2 inch port connection and fits standard piping configurations found in industrial, commercial, and mechanical system installations. Licensed pipefitters, HVAC technicians, and industrial maintenance professionals typically handle installation of this type of filter in compressed air distribution networks.

This coalescing filter is suited for compressed air applications where oil carryover from upstream compressors must be controlled before air reaches pneumatic tools, instrumentation, spray equipment, or air-actuated controls. Its compact footprint makes it practical for installations with limited inline space. The 1/2 inch port size accommodates common compressed air line sizing used in light commercial and industrial service environments.

Key Features

• Coalescing filter media captures oil aerosols and fine particulates from compressed air
• 1/2 inch port size for direct inline installation on standard compressed air piping
• Compact body dimensions of 2.87 inches wide by 9.25 inches tall for space-constrained installations
• Lightweight at 1.1 pounds for easy handling during installation or replacement
• Sold as a single unit with no minimum order complexity for individual replacement jobs

Compatibility

Designed as an OEM-style replacement coalescing filter for compressed air systems using 1/2 inch inline filter housings compatible with WILKERSON filter assemblies.

Installation Notes

Installation should be performed by a qualified technician or licensed pipefitter. Depressurize and isolate the compressed air line completely before removing any existing filter element or housing. Follow applicable codes such as ASME and local mechanical codes for compressed air piping connections. Do not exceed the rated pressure and temperature specifications of the filter housing when returning the system to service.
