Portable Class K fire extinguisher with wet chemical (potassium acetate) agent, engineered specifically for hot cooking oil and fat fires (Class K / Class F). 1 kg and 2.5 kg sizes with reusable cylinder design and quick-disconnect refill kit. Mandatory first-aid fire protection for commercial kitchens, deep fryers, restaurants and food service. CE certified. MOQ 50 units for B2B export from China.
Class K (Class F in Europe) fires involve hot cooking oils and animal fats — the most dangerous fire type in a commercial kitchen. Water is ineffective and can cause a violent oil splash; dry powder smothers but does not cool and leaves heavy residue. A wet chemical extinguisher is the only correct agent for these fires.
This Class K extinguisher discharges a potassium acetate solution that reacts with the burning oil to form a thick, soapy foam crust (saponification) over the oil surface. The foam layer cuts off oxygen, seals the oil from heat, and cools the cooking surface below its ignition temperature, preventing re-ignition even after the extinguisher is removed. The reusable cylinder design keeps operating costs low: only the agent cartridge is replaced after each discharge.
Chinese fire extinguisher manufacturers produce Class K units for the European, Middle Eastern, Asian and Australian commercial kitchen markets, alongside a full portfolio of Class A/B/C dry chemical and CO2 extinguishers. Options include 1 kg (compact, single fryer) and 2.5 kg (multiple stations, restaurant floor) sizes, with 5-year and 10-year hydrostatic refill intervals.
