PYSemi-fixed (Portable) Foam Fire Extinguishing Equipment

 I. Product Features:

Portable semi-fixed foam fire extinguishing units are primarily used in underground parking garages, chemical product warehouses, boiler rooms, ships, gas stations, power plants, and other similar facilities. They can serve as supplementary to fixed foam fire extinguishing systems or operate independently as semi-fixed foam fire extinguishing systems. Composed of foam liquid storage tanks, vacuum-type proportioning mixers, hand-pushed wheels, PQ foam guns, fire hoses, foam liquid control valves, and more. Flow rate: 4-8 (L/S), foam tank capacity: 100L-1000L. Mixing ratio: 3% or 6%.
II. Working Principle

Semi-permanent (Portable) Foam Fire Extinguishing DeviceDuring fire extinguishing, the quick connectors at both ends of the pressure-reducing ratio mixer connect the firehose to the foam gun and the fire hydrant to the water source. As the firewater flows through the ratio mixer of the portable foam tank, a vacuum is formed inside the ratio mixer. The foam extinguishing agent enters the ratio mixer through the suction tube, mixes with the firewater, and forms a foam mixture at a certain ratio. When the foam mixture flows to the foam gun, due to the foam gun's ability to draw in air, it foams the mixture. This achieves the foam fire extinguishing effect.
1. Foam has high energy and strong penetration, capable of quickly extinguishing fires.
2. The mixed ratio is stable and reliable, providing high-quality foam mixing fluid.
During the fire extinguishing process, foam fire extinguishing agent can be added at any time as needed.
3. Strong maneuverability, with its lightweight and agile extinguishing capabilities, provides wide coverage and excellent fire suppression results.
