Norgren B74G-4AK-QD3-RMG Frl Combo Unit 1/2 Npt

Product Description

The NORGREN B74G-4AK-QD3-RMG is a filter-regulator-lubricator (FRL) combination unit designed to condition compressed air at the point of use. It integrates three functions into a single inline assembly: particulate filtration, pressure regulation, and lubrication delivery. The unit accepts a 1/2 NPT port connection and handles a maximum supply pressure of 246 psi. The bowl and body are both aluminum construction, keeping weight manageable while offering durability in industrial and commercial pneumatic systems. It is installed by pneumatic system technicians, millwrights, and mechanical contractors maintaining air-powered equipment.

This FRL combination unit is suited for use in industrial facilities, manufacturing environments, and commercial mechanical rooms where clean, regulated, and lubricated compressed air is required. Typical applications include air preparation ahead of pneumatic actuators, air tools, control valves, and automated equipment. The 1/2 NPT connection size makes it appropriate for moderate flow-rate pneumatic circuits commonly found in production and process environments.

Key Features

• Three-function combination unit: filtration, regulation, and lubrication in one assembly
• 1/2 NPT port size for direct inline installation
• 246 psi maximum supply pressure rating
• Aluminum bowl and aluminum body construction for lightweight durability
• Compact footprint at 5 inches wide and 11.95 inches tall

Compatibility

Designed as an OEM-style replacement or direct-install FRL combination unit for 1/2 NPT compressed air lines in industrial and commercial pneumatic systems.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or mechanical contractor. Depressurize and lock out the compressed air supply fully before removing or installing any FRL component. Mount the unit vertically with the bowl facing down to allow proper condensate drainage, and ensure inlet and outlet flow direction matches the system circuit. Verify downstream equipment pressure requirements against the regulator output before returning the system to service.
