The extinguishing agent cylinder assembly is a new-generation core component of gas fire suppression systems, meticulously developed by Shanghai Shudun Intelligent Technology Co., Ltd. based on in-depth research into customer application requirements and years of accumulated experience in fire engineering, while fully incorporating the provisions and principles of the national standard GB 25972-2010 Gas Fire Extinguishing Systems and Components.
This series is available in multiple capacities, including 10L, 20L, 30L, 40L, 70L, and 80L, to accommodate varying agent quantity requirements for different protected zones. The product features a straightforward and intuitive structural design, facilitating easier engineering installation and routine maintenance. This enables every individual involved in fire protection system management to clearly understand its operating principles and perform effective upkeep, collectively reinforcing the fire safety defense line.

The product features a modular design and high-quality steel welded cylinders, highly integrating the storage and discharge functions of the extinguishing agent. The cylinder assembly consists of components including the container, container valve, siphon tube, pressure gauge, and gas actuator. The extinguishing agent is stored in liquid form and pressurized with nitrogen to the rated storage pressure. When a fire occurs, the control gas flow from the driving gas cylinder assembly actuates the gas actuator, which in turn opens the container valve, allowing the extinguishing agent to be rapidly discharged through the siphon tube and outlet. In emergency situations, the manual safety pin can be pulled out and the start lever pressed down to achieve mechanical emergency actuation, providing dual safeguards to ensure reliable operation at critical moments.
