Norgren B74G-4AK-QP3-RMG Frl Combination Unit 1/2 Npt

Product Description

The NORGREN B74G-4AK-QP3-RMG is a filter-regulator-lubricator (FRL) combination unit designed to condition compressed air in a single inline assembly. It filters particulates, regulates downstream pressure, and delivers lubricated air to pneumatic tooling and actuators. The unit accepts a 1/2 NPT port connection and handles a maximum supply pressure of 145 psi. The body is constructed from aluminum for durability, while the bowl is polycarbonate for easy visual monitoring of fluid and debris levels. Licensed pipefitters, millwrights, and industrial maintenance technicians typically install and service this type of unit on compressed air lines.

This FRL combination unit is suited for industrial and commercial compressed air systems where space-saving inline conditioning is required. Typical applications include pneumatic control panels, production line air drops, and machine tool air preparation stations. The 1/2 NPT port size accommodates medium-flow pneumatic circuits commonly found in manufacturing, automated assembly, and process control environments. The polycarbonate bowl allows maintenance personnel to monitor condensate and oil levels at a glance without removing the unit from the line.

Key Features

• Three-function inline assembly: filtration, pressure regulation, and lubrication in one unit
• 1/2 NPT port connection for standard compressed air piping
• 145 psi maximum supply pressure rating
• Aluminum body construction for corrosion resistance and mechanical durability
• Polycarbonate bowl enables visual inspection of condensate and lubricant levels without disassembly
• Compact form factor at 5 inches wide and 11.95 inches tall for installation in tight panel or wall-mount locations

Compatibility

Designed as an OEM-style inline air preparation unit for industrial compressed air systems using 1/2 NPT plumbing. Confirm port size, pressure range, and flow requirements against your specific system before installation.

Installation Notes

Installation should be performed by a qualified pipefitter or industrial maintenance technician in accordance with applicable local compressed air system codes. Depressurize and lock out the compressed air supply completely before installing or servicing this unit. Mount the FRL vertically with the bowl oriented downward to allow proper condensate drainage. Do not exceed the 145 psi maximum supply pressure rating during operation or testing.
