Product Description:
The Norgren B74G series represents high-performance filter regulators that form part of the Excelon modular air preparation system. These units integrate filtration and pressure regulation within a single, compact housing. This design effectively removes water and solid particles from compressed air lines, while ensuring precise control of downstream pressure.
The Excelon system’s modular design supports both in-line and modular installation alongside other Excelon products through Quickclamp connections. This feature allows for straightforward system expansion and easy maintenance, enhancing overall operational efficiency.
Available in G1/2 and G3/4 port sizes, the B74G series supports flow rates up to 100 dm³/s (212 SCFM). Its balanced valve construction helps minimize the impact of variations in inlet pressure on the outlet pressure, providing stable and reliable regulation. Users can select between 5 µm or 40 µm sintered polypropylene filter elements, combined with either manual or automatic drain options, offering versatility for diverse industrial requirements.
Maintenance and usability have been carefully considered in the B74G design. The units include a push-to-lock adjustment knob equipped with a tamper-resistant cover, a quick-release bayonet bowl for convenient servicing, and full flow gauge ports that allow pressure monitoring without restricting airflow. Additionally, the filter bowls are available either as transparent polycarbonate with protective metal guards or as durable aluminium alloy, both featuring liquid level indicator lenses to simplify condensate observation in demanding working environments.
Features:
Integrated Filter and Regulator Overview
The integrated filter and regulator unit combines both particulate filtration and pressure regulation into a single, compact device. This design helps save valuable installation space by reducing the number of separate components needed.
Excelon Modular System
The Excelon Modular System supports both in-line and modular installation configurations. It is compatible with other Excelon air preparation products through convenient Quickclamp connections, allowing for versatile and efficient system assembly.
Filtration Options
Customers can select from two filtration grades depending on their needs: 5 µm or 40 µm sintered polypropylene filter elements. These options provide effective removal of contaminants to protect downstream equipment.
Drain Configurations
Drainage is available in manual or automatic formats, providing flexibility for convenient condensate removal based on the application requirements.
Adjustment and Pressure Control Features
The unit features a push-to-lock adjustment knob that secures the pressure setting when pushed in, and an optional tamper-resistant cover enhances security. Its relieving design permits downstream pressure reduction even when the system is dead-ended.
A balanced valve design helps minimize the effects of inlet pressure fluctuations on the outlet pressure, ensuring stable and reliable pressure regulation.
Monitoring and Maintenance
Full flow gauge ports sized at 1/8" ISO Rc allow accurate pressure monitoring without restricting airflow. Maintenance is made easier with a quick-release bayonet bowl that enables fast removal of the bowl for filter element replacement and upkeep without the need for tools.
Performance and Durability
This filter and regulator can handle high flow rates up to 100 dm³/s (212 SCFM), suitable for demanding pneumatic applications. The outlet pressure can be adjusted across a wide range from 0.3 to 10 bar, with a maximum inlet pressure rating of up to 17 bar on metal bowl versions.
Construction and Environmental Resistance
The product is available with either a polycarbonate bowl, which offers 360° visibility of condensate levels protected by a metal guard for harsh environments, or a durable aluminium alloy bowl featuring a prismatic liquid level indicator lens. Both versions support operating temperatures from -34°C up to +80°C.

Support and Services:
Our Pneumatic Filter Regulator Lubricator (FRL) units are designed to ensure clean, regulated, and lubricated air supply for pneumatic systems, enhancing performance and extending the life of your equipment.
For optimal operation, regularly check and maintain the filter element to prevent clogging and ensure efficient air filtration. Replace the filter element as needed based on the operating environment and manufacturer's recommendations.
The regulator should be adjusted to the desired pressure setting according to your system requirements. Periodically verify the pressure setting to maintain consistent system performance.
The lubricator must be filled with the appropriate pneumatic oil to provide adequate lubrication to downstream components. Monitor the oil level regularly and refill as necessary to avoid dry running and premature wear.
Installation should be carried out in accordance with the flow direction indicated on the unit, ensuring proper connection to the air supply and downstream equipment. Avoid exposure to extreme temperatures and corrosive environments to maintain product integrity.
In case of performance issues, inspect the FRL unit for dirt accumulation, damaged seals, or leaks, and perform cleaning or replacement of parts as required. Always depressurize the system before performing any maintenance.
For detailed maintenance procedures and troubleshooting guidance, refer to the product manual provided with your FRL unit.
