Pro-source UMF-03N Coalescing Filter 3/8 Inch Intermediate

Product Description

The PRO-SOURCE UMF-03N is an intermediate-grade coalescing filter designed to remove oil aerosols, water vapor, and fine particulates from compressed air lines. It operates at a 0.01 micron rating, making it suitable for applications that demand clean, dry air downstream of a standard particulate filter. The polycarbonate bowl with nylon bowl guard provides visibility into the collected liquid level while protecting against impact. A semi-automatic drain removes accumulated condensate without full system shutdown. Licensed HVAC technicians, industrial maintenance techs, and pneumatic system specialists install this filter as part of a multi-stage air treatment setup.

The UMF-03N fits inline compressed air systems requiring intermediate-level coalescing filtration at a 3/8 inch port size. It is suited for residential and light commercial pneumatic tool lines, spray finishing systems, instrumentation air supplies, and HVAC control air applications where oil carryover or moisture contamination would damage downstream components or processes. The sight glass allows quick visual inspection of bowl fill level without disassembly, reducing service time during routine maintenance checks.

Compatibility

Designed as an OEM-style inline coalescing filter for compressed air systems using 3/8 inch ported filter housings requiring intermediate-grade coalescing performance.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed air system plumbing. Depressurize and lock out the air supply line before installing or servicing the filter. Mount the filter bowl in the downward vertical position to allow proper condensate collection and drain function. Follow applicable local codes and the equipment manufacturer's guidelines for thread sealant and torque practices on pneumatic fittings.
