Amerex’s Non-Magnetic Stored Pressure Deionized Water Mist Fire Extinguisher the ultimate extinguisher for Class A fires where potential Class C (electrical) hazards exist. The fine spray produced from its unique misting nozzle provides protection against electrical shock and greatly enhances the cooling and soaking characteristics of the agent. It also reduces scattering of burning materials. This unit uses de-ionized water, making it the best choice for hospital environments, valuable books and documents, telecommunication facilities and “clean room” manufacturing facilities. They’re easy to use, maintain and service, too. Charge sold separately (extinguisher comes empty).
