AFFF (Aqueous Film Forming Foam) extinguishers offer some additional benefits over water units. Not only do they typically have higher fire ratings, but they are also suitable for Class B fires involving flammable liquids. They are highly effective extinguishers with a rapid flame knockdown, and do not compromise visibility for safe building evacuation. Our Commander range consists of a 6 litre with a 21A 144B fire rating, and a 9 litre with a 27A 183B rating. Both units are 35kVa dielectrically tested and safe for inadvertent use on fires involving live electrical equipment. The units are Kitemarked and come with our full 5-year warranty.
