Extinguishing Mechanism and Product Construction
How the Powder Agent Works
When the operating lever is activated, pressure inside the cylinder drives the powder through the valve and discharge assembly. The dispersed particles interfere with the chemical reactions that sustain combustion, helping suppress flames.
For fires involving certain solid combustible materials, ABC powder can also form a coating over the burning surface, helping reduce the risk of re-ignition under suitable conditions.
Main Components

| Steel Cylinder | Stores the powder and maintains internal pressure |
| Valve Assembly | Controls the release of the extinguishing agent |

Product Use and Maintenance
Dry powder extinguishers are suitable only for fire risks covered by their certified ratings. The discharged powder can contaminate sensitive electronic equipment and machinery, so the extinguishing agent should be selected according to the surrounding environment.
Regular inspection should cover cylinder condition, pressure indication where fitted, safety seals, hose condition, and service status. Inspection, refilling, and pressure testing must follow WEIMIN's instructions and applicable local regulations.
