Norgren B73G-4AK-AP1-RMG Frl Filter Regulator 1/2 Npt

Product Description

The NORGREN B73G-4AK-AP1-RMG is a single-piece filter/regulator combination unit designed for compressed air systems requiring inline filtration and pressure regulation in a compact, intermediate-body configuration. It accepts a 1/2 NPT port connection and handles flow rates up to 123 SCFM with a maximum supply pressure of 150 psi. The unit ships with a pressure gauge included, allowing technicians to monitor downstream pressure directly at the point of regulation. An automatic drain removes accumulated condensate without manual intervention. Intended for industrial and mechanical systems, this unit is installed by pipefitters, millwrights, and pneumatic system technicians.

This filter/regulator is suited for intermediate-stage compressed air treatment in pneumatic control systems, automated machinery, and process equipment where clean, regulated air is required at a 1/2 NPT connection point. The intermediate body size positions it for mid-flow applications that fall between compact and large-line configurations. The polycarbonate bowl allows visual inspection of the condensate level without removing the unit from service. Operating environments should stay within the rated maximum temperature of 125 degrees F.

Key Features

• Single-piece filter/regulator design simplifies installation and reduces plumbing connection points
• Flow capacity of 123 SCFM suits intermediate-demand pneumatic systems
• Maximum supply pressure rated at 150 psi
• Automatic drain removes condensate without manual service intervals
• Polycarbonate bowl provides visual condensate level inspection
• Pressure gauge included for direct downstream pressure monitoring

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 removing an existing unit or installing this filter/regulator. Ensure flow direction matches the arrow marked on the body. Consult applicable mechanical and pneumatic codes for proper mounting orientation, which is typically vertical with the bowl facing down to allow proper condensate collection and automatic drain function.
