Amerex MP Series Multi-Purpose Dry Chemical Fire Extinguisher

The Amerex MP Series is a line of multi-purpose ABC dry chemical fire extinguishers available in 2.5, 5, 5A, 6, 10, and 20 lb capacities. Each unit uses a specially fluidized and siliconized mono ammonium phosphate agent that smothers Class B flammable liquid fires, fuses and insulates Class A ordinary combustibles, and provides non-conductive suppression for Class C electrical fires. Aluminum cylinder construction keeps weight low for easier handling and mounting. All models are UL Listed and ULC Listed and conform to ANSI/UL 299, ANSI/UL 711, CAN/ULC-S504, and CAN/ULC S508.

MP5 vs. MP5A — Which 5 lb Model Do You Need?

Both models weigh 5 lb and share the same dimensions, agent, and construction. The difference is UL rating: the MP5 is rated 2A-10B:C, while the MP5A carries a significantly higher 3A-40B:C rating — better coverage for ordinary combustibles and four times the flammable-liquid coverage. If your code or risk assessment calls for a higher B rating in a 5 lb package, specify the MP5A.
