Norgren B52G-2AD-DG1-FMK Filter/Regulator - NACE MR-01-75
Part Number: B52G-2AD-DG1-FMK
Quick Summary
The Norgren B52G-2AD-DG1-FMK is a stainless steel filter/regulator for clean compressed air in harsh environments. In challenging facilities, condensation and corrosion can shorten component life and disrupt production. Metallic parts meet NACE MR-01-75, and the unit is well suited for marine environments and oil and gas production. With a compact 1/4 NPT port and an integrated 5 μm filter, it delivers reliable air prep that reduces maintenance costs and extends equipment life. For engineers targeting uptime and compliance, the combination of corrosion resistance and precise pressure control translates into fewer unexpected halts and predictable performance. This makes it suitable for critical line feeds and remote installations where service access is limited.

Stainless steel construction delivers exceptional corrosion resistance in aggressive environments, extending service life and reducing lifecycle costs for offshore platforms and chemical plants. The 5 μm stainless filter element removes fine particulates before they reach downstream actuators, improving tool wear resistance and system reliability while maintaining consistent air quality at up to 84 scfm. The unit’s 1/4" NPT ports and gauge port simplify installation alongside existing plant piping, enabling rapid retrofits and modular expansions without custom adapters. Manual drain provides straightforward condensate removal, minimizing maintenance pauses, and the relieving regulator design reduces energy losses by venting excess pressure to atmosphere when setpoints are exceeded. The combination of stainless steel body, bonnet, and bowl with FPM elastomers handles wide operating temperatures from -20 to 80 °C, supporting installations from cold docks to hot process plants. The robust B52G range is optimized for marine and oil/gas applications, delivering predictable performance in harsh environments while enabling easier preventive maintenance and inventory management.

FAQs
Begin by validating that your system uses 1/4 inch NPT connections. Mount the regulator/filter unit on a stable panel or rail, align the inlet and outlet ports correctly, and attach the gauge ports for monitoring. Ensure proper torque on threads to prevent leaks, then route condensate to the manual drain. Use compatible stainless fittings to preserve corrosion resistance and simplify maintenance.
Key specs include a 5 μm stainless steel filter element, 0.5–10 bar outlet pressure range (7–145 psi), maximum inlet pressure of 31 bar, relieving operation, and a flow rate of 40 dm3/sec (84 scfm). The unit operates from -20 to 80 °C, with 1/4" NPT ports and a manual drain for condensate management, making it suitable for demanding pneumatic systems.
Yes. The B52G-2AD-DG1-FMK features stainless steel construction and is designed for corrosive environments. The metallic parts meet the NACE MR-01-75 standard, enabling use in marine environments and oil/gas production facilities where corrosion resistance and reliability are critical to uptime and safety.
Regular condensate drainage via the manual drain is required to prevent condensate build-up. Inspect the 5 μm filter element periodically and replace it when differential pressure indicates loading or at the manufacturer’s recommended intervals. Keeping the unit clean and ensuring seals (FPM elastomers) remain intact helps sustain performance in harsh environments.
