Mobile foam fire extinguishing devices are widely used in oil depots, petrochemical plants, oil pump rooms, gas stations, and other locations. Working principle: When fire extinguishing is required, connect the foam nozzle and the proportioner with a fire hose. The inlet end of the proportioner is connected to the fire hose and pressurized water. When the pressurized water flows through the proportioner's nozzle at high speed, a negative pressure is created inside the proportioner chamber. The foam concentrate in the storage tank is drawn into the proportioner through the suction pipe under atmospheric pressure, mixing with the pressurized water in a predetermined ratio to form foam solution. When the pressurized foam solution passes through the foam nozzle, it draws in air, causing the foam solution to expand and spray, covering the surface of the burning liquid to extinguish the fire.

PY Mobile Foam Fire Extinguishing Device PY4/300-PY8/500  Applicable scope: Suitable for extinguishing general Class B fires, such as oil products and grease fires, as well as Class A fires. However, it cannot extinguish water-soluble flammable liquids in Class B fires, such as alcohols, esters, ethers, ketones, etc. It is also not suitable for electrical equipment fires, Class C fires, or Class D fires.
