Pro-source NUFR-04ND Frl Combo Unit 1/2 Npt 91.81 Scfm

Product Description

The PRO-SOURCE NUFR-04ND is a three-stage FRL combination unit that integrates a filter, regulator, and lubricator into a single inline assembly for compressed air systems. Rated at 91.81 SCFM with a maximum supply pressure of 145 psi, it is built around a 1/2 NPT port and features an aluminum bowl with automatic drain. The 0.5-micron filtration rating removes particulates and moisture before air reaches downstream pneumatic tools, valves, and actuators. A pressure gauge is included for real-time line monitoring. Licensed trades and industrial maintenance technicians install this unit as part of pneumatic control and tool supply circuits.

This FRL unit fits standard compressed air distribution lines in light industrial, commercial, and trade shop environments. Typical applications include air preparation ahead of pneumatic cylinders, air tools, spray equipment, and control valve assemblies. The modular connection design allows it to be joined with compatible filter, regulator, or lubricator bodies in a side-by-side configuration. The included bowl guard, sight glass, and bracket hardware support fast installation and routine service. Operating temperature range is 14 degrees F to 140 degrees F, making it suitable for indoor shop and mechanical room use.

Installation Notes

Installation is performed by qualified pneumatic technicians or industrial maintenance personnel. Depressurize and lock out the compressed air supply line before installing or servicing this unit. Mount the assembly vertically with the bowl oriented downward to allow proper drainage and condensate collection. Follow all applicable local codes and equipment manufacturer guidelines for compressed air system assembly and pressure ratings.
