Foam Fire Extinguishing Equipment
The foam bladder tank is the main unit of the foam extinguishing system.
The device consists of pressure tank, bladder, proportioner , pressure gauge, valves and pipeline. A pump is needed to supply pressurized water. When pressurized water flow through proportioner, a small part of water(3%-6&) flow into tank from branch pipe to press the bladder to swap out equal foam concentrate and then mix with another part of water(97%-93%) to foam foam solution in proportioner and provide to foam generator.
