Norgren B52G-3AD-DG1-FMK - 3/8 NPT, 5µm, 0.5-10 bar
Part Number: B52G-3AD-DG1-FMK
Quick Summary
The B52G-3AD-DG1-FMK is a stainless steel air filter/regulator for clean, regulated compressed air in harsh industrial settings. Industrial systems often struggle with moisture, corrosion, and fluctuating pressures that drive costly maintenance and downtime. Designed for corrosive environments, the unit’s metallic parts meet NACE MR-01-75, making it suitable for marine, offshore, and oil and gas applications. This model delivers reliable filtration and precise pressure control with a robust, easy-to-install package, and it is compatible with standard 3/8 in NPT plumbing to simplify retrofits in existing lines. For engineers balancing reliability with lifecycle costs, the B52G-3AD-DG1-FMK provides a durable, scalable solution for industrial air treatment.

Feature: Stainless steel construction for both body and bonnet provides exceptional corrosion resistance in marine and offshore environments. Business Impact: Reduces replacement cycles, lowers maintenance costs, and enhances long-term system uptime. Application: Suitable for oil & gas platforms and other corrosive service where longevity matters. Feature: 5 µm filter element paired with a 3/8" NPT port design increases filtration efficiency and compatibility with common piping. Business Impact: Improves downstream tool life and product quality by delivering cleaner air. Application: Ideal for precision actuation and sensitive pneumatic tools in harsh environments. Feature: Relieving pressure regulator with 0.5–10 bar outlet range and 31 bar max inlet supports precise tuning while guarding downstream components. Business Impact: Minimizes pressure fluctuations, boosting process stability and energy efficiency. Application: Used in automated lines needing steady, configurable air pressure. Feature: Manual drain and gauge port option (1/4" NPT) offer straightforward maintenance and monitoring. Business Impact: Reduces service time and enables quick visual checks to ensure performance. Application: Retrofit in existing systems or new builds where quick drain control is beneficial. Feature: Stainless steel knob and components (adjusting knob, bowl, body, bonnet) plus FPM elastomers. Business Impact: Improves reliability under elevated temperatures and hydrocarbon exposure; lowers replacement and seal failure risk. Application: Offshore platforms and chemical processing where elastomer compatibility matters. Feature: High flow capability (40 dm3/s, ~84 scfm) supports demanding air loads while keeping pressure drop low. Business Impact: Allows one unit to serve multiple actuators, reducing inventory and installation footprint. Application: Centralized filtration and regulation in compact skid setups. Note: Some configurations ship without a gauge; verify SKU if monitoring pressure remotely is required. All features align with the B52G family for robust, industrial-grade air treatment.

FAQs
For proper installation, mount the unit with the 3/8" NPT ports facing accessible pipe runs and ensure adequate clearance for maintenance. The gauge port is 1/4" NPT on compatible SKUs, but some configurations may ship without a gauge—confirm the SKU if monitoring pressure is required. Use corrosion-resistant fittings and ensure the drain is oriented for easy access during routine maintenance.
Outlet pressure is adjusted via the built-in adjusting screw to achieve a 0.5–10 bar range. Start at the mid-point, then fine-tune while monitoring downstream pressure. Keep in mind the maximum inlet pressure of 31 bar and ensure the system is depressurized before servicing or disassembly.
Yes. The design emphasizes corrosion resistance with stainless steel body, bonnet, bowl, and adjusting knob, and it aligns with MR-01-75-style corrosion resistance expectations. This makes it suitable for marine and offshore oil & gas environments where humidity, salt spray, and chemical exposure are concerns.
Regular maintenance includes inspecting the housing for leaks, draining accumulated moisture via the manual drain, and replacing the 5 µm filter element as needed based on contamination levels in the compressed air. Documented service intervals depend on air quality and system load; consult the installation guide for replacement procedures.
