Wilkerson M18-04-BL00B Coalescing Filter 1/2 in Port

Product Description

The WILKERSON M18-04-BL00B is a coalescing filter designed to remove oil aerosols, fine particulates, and liquid water from compressed air lines. Coalescing filters work by forcing air through a fine fiber element that causes submicron droplets to merge into larger droplets, which then drain away from the airstream. This unit features a 1/2 inch port and includes an integrated sight glass for monitoring fluid accumulation without disassembly. It is a direct-replacement component used by pipefitters, pneumatic system technicians, and industrial maintenance professionals working on compressed air distribution systems.

This filter is suited for compressed air treatment applications in light industrial, manufacturing, and commercial environments where oil carryover from upstream compressors must be controlled before air reaches downstream tools, actuators, valves, or instrumentation. The 1/2 inch port size fits mid-range compressed air line configurations. The sight glass simplifies routine maintenance by making it easy to observe bowl fill levels and determine service intervals without interrupting system operation.

Key Features

• Coalescing filter element removes oil aerosols and fine particulates from compressed air
• 1/2 inch port size suits mid-range compressed air distribution lines
• Integrated sight glass allows visual monitoring of condensate accumulation
• Compact footprint: 2.36 inches wide by 8.36 inches tall
• Lightweight construction at 0.71 pounds for easy inline installation

Compatibility

Designed as an OEM-style replacement coalescing filter for compressed air treatment systems using 1/2 inch ported filter housings compatible with the WILKERSON M18 series filter body.

Installation Notes

Installation is typically performed by a qualified pipefitter or pneumatic systems technician. Depressurize and lock out the compressed air line completely before removing the existing filter element or bowl assembly. Follow applicable OSHA lockout/tagout procedures and local compressed air system codes. Do not exceed the rated pressure or flow specifications for the filter body when returning the system to service.
