This Amerex K-Class wet chemical, kitchen fire extinguisher contains a special agent with greater fire fighting capacity and cooling effect to combat hot and very difficult vegetable-based cooking oil fires. With an easy-to-use hose and swivel spray application nozzle, the chemical agent is placed exactly where you aim it with no residue to clean up. With a fine mist discharge, it helps to prevent grease splash and re-flash while cooling the appliance. It supplements existing cooking equipment automatic system protection for an extra margin of safety. This 6-liter stainless steel extinguisher is fully charged, includes wall mounting bracket and the option for an annual inspection tag.
