Wilkerson M03-02-000 Coalescing Filter 1/4 Inch Port

Product Description

The WILKERSON M03-02-000 is a miniature coalescing filter designed to remove oil aerosols, water mist, and fine particulates from compressed air lines. Rated to 150 psi maximum, it features a 0.01 micron filtration rating that targets sub-micron contaminants harmful to downstream pneumatic equipment, tooling, and instrumentation. The polycarbonate bowl provides visual monitoring of collected liquid, and the manual drain allows controlled removal of accumulated condensate. Licensed HVAC technicians, industrial mechanics, and pneumatic system installers are the typical trades handling this component.

This filter is suited for use on compressed air systems in light industrial, commercial, and trade service applications where clean, dry air is critical. Its miniature form factor makes it a practical fit for compact pneumatic panels, filter-regulator-lubricator assemblies, and point-of-use installations where space is limited. At 1/4 inch port size, it is commonly installed on small-bore air lines feeding pneumatic controls, spray equipment, and precision instruments.

Key Features

• 0.01 micron filtration rating for sub-micron oil aerosol and particulate removal
• 150 psi maximum operating pressure
• 1/4 inch port size for standard small-bore compressed air connections
• Polycarbonate bowl allows visual inspection of liquid accumulation
• Manual drain for controlled condensate removal
• Miniature body profile fits compact pneumatic assemblies and tight panel layouts

Compatibility

Designed as an OEM-style miniature coalescing filter for 1/4 inch compressed air lines in light industrial and trade pneumatic systems.

Installation Notes

Install with the bowl oriented downward to allow proper condensate collection and drainage. Depressurize and lock out the compressed air supply before servicing or replacing the filter element or draining the bowl. Use thread sealant appropriate for pneumatic fittings on the 1/4 inch port connections. Periodic bowl inspection and manual draining are recommended to maintain filtration performance and prevent re-entrainment of collected liquid.
