Norgren B54G-4AD-DM3-RKK Filter/Regulator - 40 μm, 0.5-7 bar, Relieving
Part Number: B54G-4AD-DM3-RKK
Quick Summary
Norgren B54G-4AD-DM3-RKK Filter/Regulator delivers clean, controlled compressed air for demanding offshore and chemical processing environments. This unit addresses corrosion-prone installations where downtime hurts production and maintenance budgets. Built with stainless steel across the body, bonnet, bowl, and adjusting knob, and with metallic parts meeting NACE MR-01-75, it is well-suited for marine, oil and gas, and other harsh industrial settings. The gauge-less design, 1/2" NPT ports, and manual drain simplify installation, while the 40 μm filter element protects downstream equipment. It provides relieving pressure control up to 7 bar with an adjustable outlet, enabling reliable pneumatic automation and cost-efficient air filtration in challenging environments.

Stainless steel construction across the body, bonnet, bowl, and adjusting knob delivers exceptional corrosion resistance for marine, offshore, and chemical processing environments. This reduces maintenance frequency and extends service life, improving overall equipment uptime. The 40 μm stainless filter element captures particulates before they reach actuators and valves, lowering wear, minimizing downtime, and enhancing system reliability in high-contaminant facilities. A 1/2" NPT port size with a manual drain enables straightforward installation and service, minimizing installation costs and maintenance labor in tight plant spaces. The relieving design provides safe pressure relief, protecting downstream components and operators during pressure spikes common in automated lines. Adjustable outlet pressure from 0.5 to 7 bar supports a wide range of pneumatic tools and actuators, simplifying inventory and enabling quick changeovers without replacement parts. With a flow rate of 75 dm3/sec (158 scfm), this unit supports medium-to-high demand processes, reducing bottlenecks in production lines. All internal wetted parts are stainless steel with nitrile elastomers, ensuring compatibility with clean, dry compressed air and harsh environments.

FAQs
The B54G-4AD-DM3-RKK uses standard 1/2 inch NPT ports for easy integration into most compressed air systems. It also features a 1/4 inch NPT gauge port for optional monitoring, enabling precise pressure validation without redesigning the line. This combination supports quick installations on existing manifolds and control panels.
It uses a 40 μm stainless steel filter element to protect downstream components from particulates. Maximum inlet pressure is 31 bar, with an adjustable outlet range of 0.5 to 7 bar, and a relieving design to protect equipment during pressure surges. This makes it suitable for robust pneumatic circuits in demanding environments.
Yes. The B54G series employs stainless steel components with metallic parts meeting NACE MR-01-75, delivering enhanced corrosion resistance ideal for marine and offshore oil & gas applications. Its reliving regulator design helps maintain safe operation in hazardous environments, while its rugged construction reduces maintenance cycles in harsh climates.
Maintenance is straightforward: periodically drain the manual drain to remove condensate, inspect the 40 μm element for loading or blockage, and verify outlet pressure within the 0.5–7 bar range. Because the unit is gauge-less, rely on system pressure readings and the gauge port if monitoring is required to prevent unnecessary service interruptions.
