The rugged dry chemical shell is a three piece steel assembly consisting of a seamless welded tube with a spun top, a bottom closure and a machined collar.
Each finished shell assembly is hydrostatically tested at three times the operating pressure (600 psi (41.4 bar)) and is designed to withstand a pressure of no less than six times the normal operating pressure.
Nozzle design directs the nozzle body downward when the nozzle is squeezed thus directing the agent stream at the base of the fire and increasing the chance of extinguishment.
Discharge hose is ethylene propylene diamine and is UL 92 approved for use at temperatures of -65 °F to 120 °F (-54 °C to 49 °C).
Composite guard is designed with the nozzle holster as an integral part of the one piece construction. It contains a hose retainer tab which can be used to attach the visual seal. The guard is designed to prevent its removal unless the inspection seal is broken.
Purple-K Dry Chemical A potassium bicarbonate-based agent which is the most effective ANSUL agent for knock-down of Class B (flammable liquids and gases) and Class C (electrical) fires.
High Flow (HF) Models Extinguisher is equipped with a special nozzle and nozzle tip to maximize agent flow rates. Nozzle handle is painted red to differentiate it from standard flow extinguishers.
