The ZONESUN ZS-FE1 is an automatic fire extinguisher production line designed for filling, assembling, sealing and labeling dry chemical fire extinguishers. The integrated system combines powder feeding, multi-head quantitative filling, component assembly, cylinder positioning, sealing and labeling into a coordinated automatic production workflow.

Designed for industrial-scale fire extinguisher manufacturing, the line helps reduce manual handling while improving filling consistency, assembly efficiency and production stability. The filling system, tooling and line configuration can be customized according to extinguisher size, powder characteristics, filling weight, component specifications and required production capacity.

ZONESUN can configure individual machines or provide a complete customized fire extinguisher production solution, including upstream feeding, filling, assembly, sealing, labeling and downstream handling equipment.

Complete Line Workflow

Cylinder Feeding → Dry Powder Feeding → Quantitative Filling → Component Placement → Cylinder Positioning → Automatic Sealing → Labeling → Finished Product Collection

Fire extinguisher cylinders are transferred through the coordinated production line for powder feeding, quantitative filling, component assembly, positioning, sealing and labeling. Each process can be configured according to the extinguisher specifications and production requirements.

The complete line can be customized according to cylinder size, powder type, filling weight, valve or component configuration, labeling requirements and target production capacity.
