Wilkerson M18-03-BK00B Coalescing Filter 3/8 Port

Product Description

The WILKERSON M18-03-BK00B is a coalescing filter designed to remove oil aerosols, fine particulates, and liquid moisture from compressed air lines. Coalescing filtration works by forcing air through a filter media that causes fine oil droplets and water mist to merge into larger droplets, which then drain away from the airstream. This keeps downstream pneumatic tools, actuators, and instrumentation free of contamination. The M18-03-BK00B features a 3/8 inch port and is suited for use in industrial, commercial, and mechanical trade environments where clean, dry compressed air is required for reliable system operation.

This coalescing filter is a replacement-grade unit intended for compressed air treatment systems across a range of applications including HVAC pneumatic controls, manufacturing automation, spray finishing, and general-purpose compressed air distribution. It fits inline with standard 3/8 inch compressed air plumbing and is typically installed as part of a filter-regulator-lubricator assembly or as a standalone coalescing stage downstream of a primary particulate filter.

Key Features

• Coalescing filter media removes oil aerosols and fine water mist from compressed air
• 3/8 inch port size fits standard compressed air line connections
• Compact footprint: 2.36 inches wide by 8.36 inches tall for space-constrained installations
• Lightweight at 0.71 pounds, suitable for inline mounting without additional bracketing in many setups
• Sold individually as a direct replacement unit

Compatibility

Designed as an OEM-style replacement coalescing filter for compressed air treatment systems using 3/8 inch ported filter housings.

Installation Notes

Installation is typically performed by a licensed pipefitter, pneumatic systems technician, or qualified maintenance professional. Depressurize and lock out the compressed air supply before removing the existing filter or housing bowl. Follow applicable codes such as OSHA 1910.147 lockout/tagout procedures when servicing pressurized systems. Verify flow direction markings on the filter body before completing the installation.
