Pro-source UMF-04N Coalescing Filter 1/2 Inch Intermediate

Product Description

The PRO-SOURCE UMF-04N is an intermediate-grade coalescing filter designed to remove oil aerosols, water mist, and fine particulates from compressed air lines. With a 0.01 micron rating, it captures contaminants that standard particulate filters miss, protecting downstream equipment such as pneumatic tools, spray guns, and precision air-operated devices. The polycarbonate bowl with nylon bowl guard provides a clear view of accumulated liquid while resisting impact in shop environments. A built-in sight glass allows quick visual inspection without opening the system. Installed inline by HVAC techs, pipefitters, and industrial maintenance professionals, this filter suits applications where clean, dry air is critical to equipment performance and product quality.

The UMF-04N is suited for compressed air systems in light industrial, commercial, and trade service environments. Its 1/2 inch port size fits standard pneumatic line configurations commonly found in HVAC mechanical rooms, plumbing shops, and general industrial facilities. The semi-automatic drain simplifies maintenance by releasing accumulated condensate without requiring a full manual drain cycle, reducing service interruptions during continuous operation. This filter functions as an intermediate-stage unit, typically positioned after a general-purpose particulate filter and before sensitive instrumentation or finish-coat equipment.

Installation Notes

Installation should be performed by a qualified pipefitter, HVAC technician, or industrial maintenance professional. Depressurize and lock out the compressed air system completely before removing or installing any inline filter component. Verify that the port orientation and thread type match the existing line fittings before assembly. Follow applicable local plumbing and mechanical codes for compressed air line installation and maintenance intervals.
