            product details

            1. Structure and purpose

            MPTZ/30 (45, 65) cart-type water-based fire extinguisher is composed of head, simplification, injection system, cart walking system, opening mechanism and other components. Using nitrogen as the driving gas, 3% of the simplification (AFFF) -10C) type foam fire extinguishing agent sprays out to extinguish the flame. Technical performance meets the requirements of GB8109-2005. It is mainly suitable for fighting solid fires, non-water-soluble flammable liquids, especially for the initial fires of petroleum products, and combined with a thousand powder fire extinguishers, the fire extinguishing effect is better. It is a good fire extinguisher for enterprises, factories, oil fields, oil depots, ships and other places. It is a new type of fire extinguisher. It is not suitable for fighting water-soluble combustible, flammable liquid, gas, electrical and light metal fires. 3% (AFFF-10C) foam fire extinguishing agent is composed of fluorocarbon surfactants and other additives. Because fluorocarbon surfactants drastically reduce the surface tension of the aqueous solution, it can form a water film on the oil surface. It hinders the evaporation of fuel, accelerates the flow of foam, and quickly extinguishes the fire. It is an ideal extinguishing agent.

            2. How to use

            1. When in use, unfold the hose, pull out the safety pin, raise the handle, hold the spray gun at a distance of about 5m from the burning object, and shoot at the root of the flame to extinguish the fire from far to near.

            2. The best fire extinguishing effect is downwind. Do not directly impact the oil surface when extinguishing the oil fire, so as to avoid the oil splashing and spreading the flame.

            3. When using, keep it upright and never use it lying down or upside down.
