Wilkerson M18-04-CH00B Coalescing Filter 1/2 in Port

Product Description

The WILKERSON M18-04-CH00B is a coalescing filter designed to remove oil aerosols, water mist, and fine particulates from compressed air lines. It serves as a critical point-of-use or inline filtration component in pneumatic systems, protecting downstream equipment such as air tools, actuators, valves, and precision instruments. The 1/2 inch port size suits medium-flow industrial and commercial pneumatic installations. An integrated sight glass allows technicians to monitor the liquid level in the bowl without disassembly, supporting fast service decisions during routine maintenance.

This coalescing filter is suited for industrial plants, manufacturing lines, automotive service equipment, and commercial compressed air distribution systems where oil carryover and moisture contamination must be controlled. It is installed inline on compressed air supply drops, typically downstream of a main particulate filter and upstream of regulators or lubricators. Maintenance technicians, millwrights, and industrial service professionals are the primary installers.

Key Features

• Coalescing filtration removes oil aerosols and water mist from compressed air streams
• 1/2 inch port size fits standard NPT pneumatic fittings on medium-flow distribution lines
• Integrated sight glass allows bowl level inspection without removing the filter body
• Compact footprint at 2.36 inches wide and 8.36 inches tall for space-constrained installations
• Sold as a single unit with a package quantity of one

Compatibility

Designed as an OEM-style replacement or inline coalescing filter for pneumatic systems using 1/2 inch NPT compressed air connections. Consult system documentation to confirm port sizing and flow requirements before installation.

Installation Notes

Installation should be performed by a qualified maintenance technician or millwright familiar with compressed air system service. Depressurize and lock out the compressed air supply completely before removing any existing filter or installing this unit. Verify that the port thread standard of the system matches the filter connections before applying thread sealant. Follow applicable OSHA and facility safety protocols for work on pressurized systems.
