Wilkerson M18-04-CG00B Coalescing Filter 1/2 Port

Product Description

The WILKERSON M18-04-CG00B is a coalescing filter designed to remove oil aerosols, water aerosols, and fine particulates from compressed air lines. Coalescing filtration works by forcing the airstream through a fibrous media that captures submicron droplets and allows them to drain away before clean air exits downstream. This unit accepts a 1/2 inch port connection, making it a practical fit for mid-sized pneumatic distribution systems. Licensed pipefitters, industrial maintenance technicians, and compressed air system specialists typically handle installation and service on this type of inline filter.

Coalescing filters like the M18-04-CG00B are used in compressed air systems where downstream equipment requires clean, dry, oil-free air. Typical applications include pneumatic tool supply lines, spray finishing systems, process air for instrumentation, and general industrial air preparation. The 1/2 inch port size is commonly found in commercial and light industrial installations where flow demands exceed what a 1/4 inch or 3/8 inch body can efficiently handle. This filter is sold as a single unit and is intended as a replacement or new-installation component within a filter-regulator-lubricator (FRL) assembly or standalone filtration station.

Compatibility

Designed as an OEM-style replacement coalescing filter for compressed air preparation systems requiring a 1/2 inch port inline filter body.

Installation Notes

Shut off and depressurize the compressed air supply completely before removing or installing any inline filter component. Installation is typically performed by a licensed pipefitter or qualified industrial maintenance technician following applicable OSHA and facility safety guidelines for compressed air systems. Use appropriate thread sealant on NPT connections and verify port thread type and size before assembly. Do not exceed the filter's rated pressure or flow specifications during commissioning.
