  • 3 litre, 6 litre and 9 litre size

Wet chemical

Fire class: F

These fire extinguishers are designed for use on cooking oils.

Class F – Wet chemical fire extinguishers, available in 2 litre, 3 litre and 6 litre sizes giving 5A/40F, 8A/75F and 13A/75F fire ratings respectively.

40F and 75F rating means the extinguishers have extinguished either a 40 litre or 75 litre test fire of cooking oils heated to their auto ignition temperature.

How It Works:

The chemicals react with the heat and the frying media creating a crust on the surface with porridge like consistency (known as the saponification), which extinguishes the fire in normally just a few seconds (5-10). The extinguishant also permeates through the frying media and makes any chance of re-ignition impossible. Can also be used on Class A fires.
