Amerex 423 20 lb ABC Dry Chemical Fire Extinguisher
FSP · P-02
What it is
Amerex 423 is a 20 lb ABC dry chemical fire extinguisher rated 10A:120B:C for ordinary combustibles, flammable liquids and gases, and live electrical equipment. Discharge runs 30 seconds with an initial range of 15 to 21 ft at 195 PSIG. The agent is a specially fluidized and siliconized mono ammonium phosphate that melts and coats the burning surface, insulating Class A fuel and breaking the chain reaction on Class B fires. The cylinder is drawn-steel with a chrome-plated brass valve body, stainless steel handle and lever. A wall bracket ships with the extinguisher. The operating temperature range is −65°F to 120°F.
Twenty pounds of ABC dry chemical make the Amerex 423 a workhorse for warehouses, loading docks, manufacturing floors and large retail spaces where a 5 lb unit simply runs out too soon. Rated 10A:120B:C, it covers ordinary combustibles such as wood, paper and fabric alongside flammable liquids and energized electrical equipment. This is the brass-valve build of Amerex's 20 lb platform: a heavy-duty chrome-plated brass valve body with a stainless steel handle and lever, mounted on a dependable drawn steel cylinder finished in durable high-gloss polyester powder paint. Bilingual labels and straightforward serviceability keep the 423 easy and economical to maintain over a long working life.
