商品簡述
This product uses the water pressure of the fire hose to press the bag in the tank so that the foam concentrate in the bag can be mixed with the water in the fire hose in the mixer into the 3% or 6% water/foam mixture according to the preset volume. The mixture will then flow through various foam generators in the protected area and generate foam to extinguish the fire. In addition, the mixture ratio stays the same whether the water pressure in the main hose rises or drops.
