Wilkerson M18-03-CH00B Coalescing Filter 3/8 Port

Product Description

The WILKERSON M18-03-CH00B is a coalescing filter designed to remove oil aerosols, fine particulates, and liquid water from compressed air lines. It serves as a critical inline filtration component in pneumatic systems, protecting downstream equipment such as valves, actuators, and air tools from contamination. The 3/8 inch port size suits standard compressed air distribution lines in light industrial and commercial applications. An integrated sight glass allows technicians to visually monitor the liquid level in the bowl without interrupting service, reducing maintenance downtime and supporting predictive service intervals.

This coalescing filter is suited for use in compressed air systems found in manufacturing facilities, maintenance shops, HVAC control air circuits, and similar environments where clean, dry air is essential to equipment performance. It is typically installed inline at point-of-use locations or at system headers where oil carryover from compressors must be addressed before air reaches sensitive components. The 3/8 inch port makes it compatible with common quarter-turn fittings and standard pipe thread connections used throughout industrial and commercial pneumatic distribution.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed air system service. Depressurize and lock out the air supply before removing or installing any inline filter component. Follow applicable facility safety procedures and any local codes governing compressed air systems. Ensure proper orientation per the flow-direction marking on the filter body to maintain correct coalescing function.
