Stainless steel construction provides exceptional corrosion resistance, reducing maintenance and replacement costs in harsh environments such as marine and petrochemical facilities. The 1/4" PTF port and panel-mount design streamline installation, enabling quicker integrations into control panels without custom brackets. The 5 μm filter element traps fine particulates, improving downstream actuator and sensor life and reducing contamination-related downtime. A manually operated drain simplifies condensate removal, while the relieving regulator maintains stable pressures during venting, protecting equipment and operators. Adjustable outlet pressure from 0.3 to 8.5 bar (4 to 123 psi) supports precise control for pneumatic tools and instrumentation. With a maximum inlet pressure of 20 bar, it tolerates most plant air systems while preserving performance. The sintered polyethylene filter element and FPM elastomers enhance compatibility with common industrial fluids and provide reliable seals across cycles.

FAQs
Installation begins with selecting a suitable panel mounting location and using the panel mounting provisions noted in the data sheet. The unit is designed for panel mounting and is compatible with standard mounting hardware referenced in the Norgren accessory catalog, such as panel nuts and mounting brackets. Ensure the 1/4" PTF port is connected to the supply line and the 1/8" gauge port is monitored to verify set pressure. Verify clearance for drain operation and access for maintenance, then tighten all fittings to the specified torque values to prevent leaks.
Key performance specs include a 1/4" PTF port size, a 5 μm filter element, manual drain, relieving regulator action, and an adjustable outlet pressure range of 0.3–8.5 bar (4–123 psi). The maximum inlet pressure is 20 bar, and flow is rated at about 7 dm3/sec (15 scfm). The gauge port is 1/8" PTF for monitoring pressure and ensuring stable operation.
Yes. The unit uses stainless steel body components and metallic parts designed to meet NACE recommendations, which supports corrosion resistance in challenging environments typical of marine and petrochemical facilities. Its panel-mount design facilitates integration into rugged control panels, while the 5 μm filtration helps maintain air quality in demanding processes like processing, packaging, or automated tooling in these sectors.
The provided data highlights NACE-recommended metallic parts and stainless steel construction, contributing to regulatory compliance in difficult environments. Specific certifications such as SIL or CE are not listed in the data set; for definitive certification status, refer to the official datasheet and the manufacturer’s compliance documentation. When in doubt, verify with your procurement team and the supplier for current accreditation details.
Maintenance is straightforward: use the manual drain to remove condensate, inspect the 5 μm filter element regularly, and replace the filter element as needed with the provided spare parts. Service kits are available (R05-KITR for general service and 3820-08 for B05 kits), and there are compatible mounting accessories (e.g., panel nuts) to simplify periodic service without disassembly. Regular upkeep reduces downtime and extends component life.
