What is the fire hose nozzle?
Handline nozzles are one of the most important fire fighting gears for the firefighters to put out fires. A handline nozzle is connected to the fire hose that provides water flow to extinguish fires. The quality of the handline nozzle that you choose ensures effective fire extinguishing and better water flow.
Three major functions of fire hose nozzles:
- Provide stable reaches through special designed outlets that regulate the water flow
- Project water to the fire spot within range
- Offer stream mode for long-distance targets and fog mode for firefighters safety
The kind of handline nozzles you should choose depends on the kind of fire extinguishing strategies and goals you want to pursue. Let us first take a quick look at the four most commonly seen handline nozzles on the market:
- Constant gallonage handline nozzles
- Selectable gallonage handline nozzles
- Automatic pressure handline nozzles
- Multi Purpose handline nozzles
1.Constant gallonage fire nozzles
Water flows are fixed (e.g. 150GPM@100 psi), which means the handline nozzle’s water flow is 150 GMP when the pressure is set at 100 psi. This pre-set device can save precious time for firefighters in the missions because they can extinguish fires without taking the time to modulate the water flow that might endanger their lives.
2. Selectable gallonage fire nozzles
Water flows can be selected by the firefighter based on the fire situations. This can be easily done without turning off the nozzles.
3 Automatic pressure fire nozzles
This newly designed device can maintain various water flows at certain pressure to ensure the reach, but at the expense of the water flow performance because the pressure is maintained by regulating the water flow in the nozzle.
4.Multi Purpose fire nozzles
This is a hybrid nozzle that can activate fog mode while it is in stream mode so that the firefighters too close to fires might not be hurt. Its lower pressure can also provide bigger water flow needed for fire-fighting of high rise buildings and outdoor areas as well as CAF systems and cooling fire areas, etc.
We will talk about how to choose the right nozzles next.
