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

Product Description

The PRO-SOURCE NUFR/L-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 to 145 psi maximum supply pressure and 91.81 SCFM flow capacity, it conditions incoming air before it reaches downstream pneumatic tools, actuators, or control equipment. The 0.5-micron filtration stage removes particulate and moisture, the regulator controls output pressure, and the lubricator introduces a measured oil mist for equipment that requires it. A pressure gauge is included and mounted. Installation is handled by industrial maintenance technicians and pneumatic system specialists working in manufacturing, automation, and process environments.

This FRL unit is suited for industrial and commercial compressed air circuits where consistent air quality and pressure regulation are required at a single inline connection point. The 1/2 NPT port size fits common supply line sizes used in production and facility maintenance settings. Modular connections allow integration with other compatible FRL components when system expansion is needed. The automatic drain removes collected condensate without manual intervention, reducing maintenance intervals on high-cycle systems.

Compatibility

Designed as an OEM-style inline FRL replacement or new installation unit for compressed air systems with 1/2 NPT supply and outlet connections operating within the rated pressure and temperature range.

Installation Notes

Installation is typically performed by qualified industrial maintenance personnel or pneumatic system technicians. De-pressurize and lock out the compressed air supply before removing an existing FRL unit or installing this assembly. Verify that supply pressure does not exceed 145 psi and that operating temperature remains within the rated range before commissioning. Consult applicable facility safety codes and equipment manufacturer guidelines when sizing and positioning the unit in the air circuit.
