Overview for Amerex B479T 5 lbs Purple-K Fire Extinguisher w/ Aluminum Valve (Class B:C)

The Amerex B479T 5 lbs Purple-K Fire Extinguisher w/ Aluminum Valve (Class B:C) efficiently stops Class B fires caused by flammable and combustible liquids like gasoline, lacquers, alcohol, and oil-based paints. It’s non-conductive so it is safe for fires involving electrical equipment. With a UL rating of 30B:C, a single unit can fight 30 square feet of Class B fires. It's also rechargeable after discharge.

Superior firefighting performance. The Amerex B479T uses Purple-K agent, a potassium bicarbonate-based dry chemical with an added purple pigment. Due to higher amounts of potassium ion, Purple K is proven to be at least 4 or 5 times as effective as carbon dioxide and more than twice as effective as sodium bicarbonate-based fire suppressants. Purple-K is non-abrasive, non-toxic, and is also compatible with most foam concentrates. When used, Purple-K leaves a residue that can easily be cleaned up by vacuuming. Unlike gaseous extinguishers, it is less affected by wind and also results in a moderate flare-up and minimal spread of flame. The Amerex Purple K extinguishers are safe to use from –65 °F and as high as 120 °F (–54 °C and 49 °C).

Rugged, reliable build. Known for its high-quality fire extinguishers, Amerex guarantees superior performance and long-lasting durability in its products with proper maintenance and service. This Purple K Class B:C extinguisher features a stored pressure design with sturdy drawn steel cylinders, high-gloss polyester powder paint, and an anodized aluminum valve. The all-metal construction makes it durable enough to withstand fire and future recharges unlike fire extinguishers with plastic parts.  It comes with a nozzle and hose for easy maneuvering. The Amerex B479T is safe to use in temperatures ranging from -65°F to 120°F. It is ANSI/UL approved and manufactured to standards under ISO-9002, QR-coded, have bilingual labels, and contain required HMIS information.

Configuration Options

The Amerex B479T Purple-K Fire Extinguisher is available in red or chrome finish. Chrome is easier to blend with the background, making it the preferred extinguisher in locations such as hotels, reception areas, modern offices, upscale restaurants, etc. However, since it’s not as easy to spot as its red counterpart, it needs to be accompanied by easy-to-read signage.
