Norgren B74G-4AK-AD3-RMG Frl Unit 1/2 Npt 246 Psi

Product Description

The NORGREN B74G-4AK-AD3-RMG is a filter-regulator-lubricator (FRL) combination unit designed to condition compressed air at the point of use. Integrating three functions into a single inline assembly, it filters particulate and moisture, regulates downstream pressure, and delivers metered lubrication to pneumatic tools and actuators. The unit accepts a maximum supply pressure of 246 psi and connects via a 1/2 NPT port. Both the body and bowl are aluminum, keeping weight manageable while maintaining durability in typical industrial and mechanical service environments. Licensed HVAC technicians, pipefitters, and industrial maintenance professionals install this type of unit as part of a pneumatic service drop.

The B74G-4AK-AD3-RMG suits compressed air systems in light to medium industrial applications where consistent air quality and regulated supply pressure are required. It is appropriate for use upstream of pneumatic control valves, cylinders, air tools, and automated equipment that depend on clean, dry, and lubricated air. At 5 inches wide and 11.35 inches tall, the unit fits standard panel or inline mounting arrangements without requiring significant rework of existing service lines.

Key Features

• Three-in-one FRL design combines filtration, regulation, and lubrication in a single assembly
• Maximum supply pressure of 246 psi supports a broad range of compressed air service conditions
• 1/2 NPT port connection for straightforward integration into standard pneumatic piping
• Aluminum body and bowl construction — corrosion-resistant and lightweight
• Compact footprint: 5 inches wide, 11.35 inches tall

Compatibility

Designed as an OEM-style inline FRL unit for compressed air systems utilizing 1/2 NPT ported pneumatic plumbing; verify downstream equipment pressure ratings before installation.

Installation Notes

Installation should be performed by a qualified pipefitter or industrial maintenance technician familiar with compressed air system service. Depressurize and lock out the air supply line before installing or servicing the unit. Follow applicable OSHA and local compressed air piping codes for mounting orientation and support. Do not exceed the rated maximum supply pressure of 246 psi under any operating condition.
