Wilkerson M03-02-D00 Coalescing Filter 1/4 Inch Port

Product Description

The WILKERSON M03-02-D00 is a miniature coalescing filter designed to remove oil aerosols, liquid water, and fine particulates from compressed air lines. It features a polycarbonate bowl, a piston-style drain, and a 1/4 inch port for integration into compact pneumatic systems. With a maximum operating pressure of 150 psi and a 0.003 micron rating, it provides high-efficiency filtration suitable for sensitive downstream equipment including instrumentation, pneumatic controls, and precision actuators. Compressed air system technicians and industrial maintenance professionals install this filter as part of air preparation assemblies.

This coalescing filter is suited for light industrial and commercial compressed air systems where clean, dry air is critical. The miniature form factor fits tight panel or manifold installations. Its 1/4 inch port size matches common small-bore pneumatic lines. Typical applications include point-of-use filtration ahead of regulators, lubricators, or pneumatic control valves in process and automation environments. The polycarbonate bowl allows quick visual inspection of collected liquid without disassembly.

Key Features

• 0.003 micron filtration rating removes fine oil aerosols and sub-micron particulates
• 150 psi maximum operating pressure suits standard industrial compressed air systems
• Piston drain for manual removal of collected condensate
• Polycarbonate bowl provides visible inspection of liquid accumulation
• Miniature footprint with 1.69 inch width supports compact air preparation stations
• 1 oz bowl capacity appropriate for low-flow point-of-use installations

Compatibility

Designed as an OEM-style replacement or new-installation coalescing filter for 1/4 inch port miniature compressed air preparation systems.

Installation Notes

Installation should be performed by a qualified compressed air systems technician or industrial maintenance professional. Depressurize and lock out the compressed air supply before removing or installing any filter element or bowl assembly. Ensure the filter is oriented with the bowl facing downward to allow proper condensate collection and drainage. Follow applicable local codes and the system manufacturer guidelines for torque and sealing of threaded port connections.
