Product Description:
The Norgren B72G and B73G series represent high-performance filter regulators within the Excelon modular air preparation system. These integrated devices combine both filtration and pressure regulation functionalities into a single, compact unit. They effectively remove water and solid contaminants from compressed air lines while ensuring accurate control of downstream pressure.
Designed with versatility in mind, the Excelon system supports both in-line and modular installations. The use of Quickclamp connections allows these units to easily connect with other Excelon components, facilitating straightforward system expansion and simplified maintenance procedures.
The B72G series is equipped with G1/4 and G3/8 port options and provides a flow rate of 38 dm³/s (80 SCFM). In contrast, the B73G series offers a broader selection of ports including G1/4, G3/8, and G1/2, alongside a higher flow capacity of 50 dm³/s (106 SCFM). Both series incorporate a balanced valve design that minimizes the impact of inlet pressure fluctuations on outlet pressure, thereby delivering stable and reliable regulation.
These filter regulators are available with sintered polypropylene filter elements rated at either 5 µm or 40 µm and come with manual or automatic drain options. This range of configurations ensures adaptability to meet diverse industrial requirements.
Additional features include a push-to-lock adjustment knob safeguarded by a tamper-resistant cover, and a quick-release bayonet bowl which simplifies maintenance tasks. Full flow gauge ports are integrated to allow pressure monitoring without restricting airflow. The transparent polycarbonate bowls provide clear 360° visibility of condensate levels, while robust zinc and aluminium body constructions guarantee durability even in demanding operating environments.
Features:
