Norgren B73G-4AK-AD1-RMG Frl Filter Regulator 1/2 Npt

Product Description

The NORGREN B73G-4AK-AD1-RMG is a single-piece filter/regulator combination unit designed for compressed air systems requiring inline filtration and pressure regulation at one service point. This intermediate-body unit accepts 1/2 NPT connections and handles up to 250 psi supply pressure with a maximum flow rate of 123 SCFM, making it suitable for demanding pneumatic circuits in industrial and commercial environments. The aluminum bowl resists corrosion under normal service conditions, and the built-in automatic drain eliminates the need for manual bowl maintenance. A pressure gauge is included for immediate downstream pressure verification. Licensed industrial mechanics, pipefitters, and pneumatic system technicians are the primary installers.

This FRL unit fits into compressed air distribution systems where a combined filter and regulator is preferred over separate components. The intermediate body size is appropriate for branch lines and point-of-use applications on production equipment, pneumatic tooling stations, and process control panels. The integrated sight glass allows visual inspection of bowl level and condensate accumulation without removing the unit from the line. At 123 SCFM capacity, it supports moderate to high-flow pneumatic circuits found in light manufacturing, assembly, and automated process environments.

Key Features

• Single-piece filter/regulator design consolidates filtration and pressure regulation into one compact unit
• Automatic drain removes condensate without manual intervention
• 250 psi maximum supply pressure rating for high-pressure compressed air systems
• 123 SCFM flow capacity supports moderate to high-flow pneumatic applications
• Includes sight glass for visual bowl inspection during operation
• Pressure gauge included for immediate downstream pressure readout

Compatibility

Designed as an OEM-style replacement or new-installation filter/regulator for compressed air systems using 1/2 NPT porting in intermediate-body FRL configurations.

Installation Notes

Installation should be performed by a qualified pipefitter or pneumatic systems technician. Depressurize and lock out the compressed air supply completely before installing or servicing this unit. Mount the unit vertically with the bowl facing downward to allow proper condensate drainage and automatic drain function. Verify all NPT thread connections are sealed with appropriate thread sealant rated for compressed air service before pressurizing the system.
