Amerex 491 Dry Chemical Nitrogen Cylinder Operated Extinguisher 300 lb.

Nitrogen Cylinder Operated – 125/150, 300/350 lb. Direct Pressure ABC, Regular, Purple K Dry Chemical

125 lb. ABC & Purple K and 150 lb. Regular Direct Pressure extinguishers utilize a 23 ft3 nitrogen cylinder with a “quick opening brass valve” to pressurize and completely discharge the agent cylinder. The compact size and 16″ semi-pneumatic tires allow easy maneuvering and operation by one person, through narrow doorways and aisles. A 4″ stainless steel fill opening with rugged chrome plated brass cap makes servicing easier. For large hazards choose the 300 lb. ABC or Purple K or 350 lb. Regular Direct Pressure extinguishers with a “quick opening” 55 ft3 nitrogen cylinder. They provide quality and economical fire protection, large volume capacity for extra high hazard areas with single person transport and operation. The 36″ X 6″ wide steel wheels make movement possible in sandy or soft soil.

About Amerex

Amerex Corporation® is a large American manufacturer of firefighting products. Based in Trussville, Alabama. Amerex makes hand portable and wheeled fire extinguishers for commercial and industrial environments, as well as fire and explosion suppression vehicle systems for defense applications. Amerex’s innovative technology has led to the production of automatic restaurant systems, vehicle fire suppression systems, gas detection, industrial systems and fire detection devices. McWane, Inc. acquired Amerex in 1999.

Amerex was founded in 1971 by Ned Paine and George Baureis. Paine was part of the Amerex team until his retirement in September 1999. He sold the company to McWane, Inc. In 2010, Amerex began emerging as a major military subcontractor after developing a U.S. military fire suppression system. These suppression systems are still being deployed on U.S. military vehicles often targeted by mines and homemade bombs in the Middle East. The company is a subcontractor of the Oshkosh Corporation. The Oshkosh Corporation is a maker of military vehicles. The vehicles use safety equipment, including fire suppression gear, made for Oshkosh vehicles. Optical sensors are used to detect fires and explosions instantly, which then directs a series of jets and hoses to put out the fire with a concealed substance.

In 2011, Amerex acquired The Solberg Company, another firefighting equipment company based in Bergen, Norway. According to Amerex President Bill Beyer, the fire extinguisher sales tend to follow the general economy and growth in new buildings. Amerex produces 2.5 million commercial and industrial fire extinguishers each year.
