A foam gun or deck gun can be found fitted to fireboats and fire trucks for use in manual fire fighting efforts. It can be aimed and operated by one firefighter and is used to deliver water or foam from outside the immediate area of fire.
It can be used to connect threaded coupling nozzel and fire hose nozzel,through fire pressure and foam and inhale air,and produce air foam. air foam gun compose of tube, gun, body, ball valve, pipette and KY 65 threaded coupling nozzel, it's used for put out I.II.III. kind liquid fire or spray water and put out general solid fire.
The air foam fire nozzle is made up of gun barrel , hand wheel , gun bady, ball valve,connector.It is portable fire nozzle which can generate and jet air bubble.Using orifice plate to make water speed to make vacuum differential pressure sunction foam liquid, and maek it mixes with air injection.
The air bubble gun performance good, small size, light and flexible , easy to operation , widely usd in all kinds of fire extinguishing.
Features:
1. Good performance, small size, light and flexible ,easy to operation
2. Can use under the condition of fire system supply all kinds of foam liquid of 3%-6%
3. Can use under the condition of fire system supply presure water and self-absorption
4. When jection along the wind direction
