Mechanical Foam Fire Extinguisher (AFFF or AR-AFFF) has the ability to from an aqueous film, which quickly forms over water insoluble hydrocarbon fuel surfaces causing rapid fire extinguishment and vapour suppression for Class B fires. It also provides excellent penetrating and wetting qualities when used on class A fires.
Foam Based Fire Extinguisher can be used on class A and B Fires. They are most suitable to extinguishing flammable liquids containing materials such as petrol, diesel, solvents and fats like grease and oils.
Mechanical foam type fire extinguishers are useful for paints, lubricants, chemical industry, oil fire/refinery, kitchen/restaurant, boiler room, etc.
