Mechanical Foam Fire Extinguisher is a powerful flame reducing agent for `spill` fires involving flammable and volatile liquids like petrol, paints and other solvents. The Fire Extinguisher forms a thick blanket of foam over the burning surface, effectively cutting off the oxygen supply there by smothering the fire and preventing re-ignition. The Fire Extinguisher is also highly effective against A and B class of fire. Mechanical Foam Fire Extinguisher has a distinguishing feature of high performance deep drawn bodies, plastic coated gas cartridges and internal plastic coating.
