Fire fighting with Pressure type Foam mixer ratio device:
Principle of operation:
Pressure type foam proportion mixing device consisted of foam liquid saving box,
Pressure type proportion mixer, capsule, safety valve, control valve, liquid level gauge and accessory spare parts. When the fire-fighting pressure water flowing into foam mixing ratio device, the water will proportion bypass flow, a small part of water will flowing into the foam liquid saving box with capsule, pressing capsule, it will swap out foam liquid proportion mixing other part of fire-fighting water to be foam liquid, it delivered to high expansion foam sprayer.

High expansion air foam sprayer(fixed type)
Principle of operation:
High expansion air foam sprayer will mix foam mixing liquid with air in a very short time, come into being a lot of foam, covered fire rapidly, put out a fire quickly. High expansion sprayer only use minimum water, avoid water spots damage, remove exhaust gas and poisonous gas effectively. Application in airport hangar, garage,oil depot,mine,liquefied petroleum gas station, oil terminal,library, archive, many industry factories.
