Suspensory powder auto extinguisher is composed of a tank, a temperature-responsive glass sprinker, a pressure gauge and a hanger. It is filled with sodium hydrogen carbonate powder and proper driving nitrogen. It has the advantages of high extinguishing effciency, small corrosion, good  isolation and non-deterioration after a long time  of storage. Temperature-responsive glass sprinkler is equipped  at the outlet. In case of fire, after the temperature rises, the liquid inside the glass  ball will expand and break the glass, and the extinguishant will spray out for auto extinguishments.  Suspensory powder auto extinguisher  has a reasonable structure without any pipe and wire connection. It is especially applicable to partial fire of oil depot, paints warehouse, power distributing room, ships and laboratory and is one of the effective indoor auto extinguishers.
