AFFF Mechanical Foam Fire Extinguishers in HQ series with Body made up of Stainless Steel Smooth Finish gives an aesthetic impression and are capable of fast, powerful means of tackling flammable liquids. Also these extinguishers works on the simple principle of cutting off the supply of oxygen required to sustain a fire. The foam smothers the flames and forms a compact blanket over the fire, preventing it from spreading or re-igniting. . Ideal for multi-risk usage and also applicable against Class ‘A’ hazards such as wood, cloth, trash, and other materials that leave an ash.
Aqueous Film Forming Foam concentrate, produces thin, yet strong film on the surface of hydrocarbon fuels thereby sealing the fuel surface and preventing fuel vapour release.
Due to presence of Fluorocarbon surfactant the spreading characteristic of the foam is such that a positive, fast spreading coverage action takes over the fuel surface, resulting fast extinguishment.
The synthetic base imparts good shelf life of the concentrate free from settling ingredients and bad odour.
