Wilkerson M28-03-CG00B Coalescing Filter 3/8 Port

Product Description

The WILKERSON M28-03-CG00B is a coalescing filter designed to remove oil aerosols, water droplets, and fine particulates from compressed air lines. It serves as a critical point-of-use or inline filtration component in pneumatic systems found in industrial, HVAC, and mechanical service environments. With a 3/8 inch port size, this filter is sized for moderate-flow compressed air circuits. Coalescing filtration works by causing small liquid droplets to merge into larger ones that drain away, protecting downstream equipment such as valves, actuators, and instrumentation from contamination.

This filter is suited for compressed air treatment in commercial and light industrial applications where oil carryover from compressors must be controlled. Typical installations include point-of-use filter stations ahead of pneumatic tools, control valves, or air-powered HVAC equipment. It is installed and serviced by HVAC technicians, pipefitters, and industrial maintenance personnel who maintain compressed air distribution systems. The 3/8 inch port accommodates standard threaded fittings common in these piping configurations.

Key Features

• Coalescing filter element removes oil aerosols and water droplets from compressed air
• 3/8 inch port size fits standard compressed air line connections
• Compact footprint at 2.87 inches wide and 9.25 inches tall for tight installations
• Sold individually, allowing single-unit replacement without excess inventory
• Protects downstream pneumatic components from liquid and oil contamination

Compatibility

Designed as an OEM-style replacement coalescing filter for use in standard compressed air filter assemblies with 3/8 inch ported connections.

Installation Notes

Coalescing filters are installed and serviced by qualified HVAC technicians, pipefitters, or industrial mechanics. Before service, depressurize the compressed air line completely and isolate the section with an upstream shutoff valve. Verify that the port thread type and size match the existing fitting before installation. Follow applicable local mechanical codes and the equipment manufacturer guidelines for filter service intervals and element replacement.
