Pro-source NUF-04N Compressed Air Filter 1/2 in Npt 5 Micron

Product Description

The PRO-SOURCE NUF-04N is a standard compressed air filter designed to remove particulate contamination from compressed air lines in industrial and commercial pneumatic systems. It features a 5-micron polyethylene filter media that captures fine particles before they reach downstream equipment such as valves, actuators, and air tools. The 1/2 inch NPT port accommodates common line sizes, and the unit flows up to 106.99 standard cubic feet per minute (SCFM), making it suitable for moderate to high-demand applications. A polycarbonate bowl with integral bowl guard and integrated sight glass allows visual monitoring of the condensate level without interrupting service. Compressed air system technicians and industrial maintenance professionals are the primary installers.

This filter is suited for use in compressed air distribution systems in manufacturing, maintenance, and process environments where clean, dry air is critical to equipment performance. The semi-automatic drain and 3.7-ounce bowl capacity reduce manual service intervals compared to manual-drain designs. The modular connection design allows integration into filter-regulator-lubricator (FRL) assemblies. With an aluminum body construction and a minimum operating temperature of 14 degrees F, this unit is appropriate for both indoor and environmentally controlled outdoor installations.

Key Features

• 5-micron polyethylene filter media removes fine particulate from compressed air supply lines
• Semi-automatic drain reduces manual maintenance intervals
• Polycarbonate bowl with bowl guard allows safe visual inspection of condensate level
• Integrated sight glass for at-a-glance bowl monitoring without disassembly
• Modular connection design supports FRL assembly configurations
• 1/2 inch NPT port with up to 106.99 SCFM flow capacity

Compatibility

Designed as an OEM-style replacement or inline addition for standard compressed air filtration applications using 1/2 inch NPT ported pneumatic components and FRL assemblies.

Installation Notes

Installation should be performed by a qualified industrial maintenance technician or pneumatic systems professional. Depressurize and lock out the compressed air supply line before installing or servicing the filter. Mount the unit in the correct flow direction as indicated on the body, with the bowl oriented downward to allow proper condensate collection. Verify that all NPT threaded connections are properly sealed with an appropriate thread sealant compatible with compressed air service.
