Norgren B54G-4AD-AC3-RKK Filter/Regulator - NACE MR-01-75
Part Number: B54G-4AD-AC3-RKK
Quick Summary
B54G-4AD-AC3-RKK is a stainless steel filter/regulator for compressed air in challenging industrial settings. Operators grapple with corrosion, moisture, and downtime when selecting components for offshore, marine, or oil-and-gas systems. Metallic parts meet NACE MR-01-75, and the stainless steel construction supports reliability in corrosive environments. With an adjustable outlet pressure, automatic drain, and a compact 1/2" NPT footprint, this unit helps reduce maintenance costs while ensuring consistent performance in demanding automation setups. Designed for corrosion resistance across marine, offshore, and chemical processing environments, it integrates with standard 1/2 inch piping and a 1/4 inch gauge port. Choosing this regulator/filter can improve downstream actuator life and reduce energy losses through stable pressure control.

Stainless steel construction across the body, bonnet, bowl, and adjusting knob provides exceptional corrosion resistance in salt spray, chemical exposure, and humid environments. Business impact: longer service intervals, reduced spare-parts costs, and lower risk of unexpected failure in offshore and marine facilities. Application: seamless retrofit in existing pneumatic networks with standard 1/2" NPT piping. The 40 μm stainless steel filter element delivers reliable particulate removal to protect downstream valves and actuators. Business impact: improved tool life, fewer maintenance cycles, and higher system reliability in rugged plants. Application: essential for compressed air lines feeding sensitive cylinders in automation lines. Automatic drain handles condensate autonomously, minimizing manual maintenance and condensate carryover. Business impact: reduced labor cost and dryer/receiver requirements. Application: moisture-prone environments such as offshore rigs and chemical plants. Outlet pressure is adjustable from 0.5 to 7 bar, enabling precise, stable control of downstream actuators. Business impact: fewer calibration steps, energy savings, and smoother cycle times. Application: pneumatic cylinders and grippers in packaging, robotics, and material handling. Relieving regulator design ensures safe venting and stable supply under changing conditions; gauge port 1/4" NPT allows monitoring. Business impact: safer operation and faster diagnostics in critical lines. Application: pressure-sensitive automation where quick response matters. High maximum inlet pressure up to 17 bar and a flow capacity of 75 dm3/sec (158 scfm) support demanding plant air systems, while the stainless steel elastomers resist chemical attack. Business impact: robust performance in harsh environments and longer system life.

FAQs
Plan for standard 1/2" NPT ports on the main line and utilize the 1/4" NPT gauge port for monitoring. Ensure compatible fittings, proper mounting orientation, and adequate space for the automatic drain to prevent condensate pooling. Verify downstream connections match the 0.5–7 bar outlet range to avoid over-pressurizing actuators.
Prioritize the 1/2" NPT port size, 40 μm filtration, automatic drain, relieving regulation, and a 0.5–7 bar adjustable outlet. Also note the maximum inlet pressure of 17 bar and the stainless steel construction, which collectively support longevity and stable pressure control in corrosive settings.
Yes. The unit is designed for corrosive environments and features metallic parts that meet NACE MR-01-75, aligning with offshore reliability requirements. Its stainless steel design, 1/2" NPT ports, and condensate management make it well-suited for marine and oil/gas processing environments.
Set the outlet pressure using the adjustment screw to a range of 0.5 to 7 bar (7 to 102 psi). This allows precise control for downstream actuators and ensures consistent performance across varying loads. Always monitor with the gauge port for real-time verification.
Expect extended service intervals due to stainless steel construction and 40 μm filtration, which protects sensitive downstream equipment. Automatic drain reduces manual maintenance, lowering labor costs, while stable pressure reduces energy waste and downtime, delivering a favorable return on investment in demanding facilities.
