Scene Application Guide

 

Fire brigade combat configuration

• Urban fire protection: 2.5 "interface +8L/S high flow rate, dealing with high-rise building fires
• Industrial fire protection: 2 "interfaces + adjustable flow rate, precise handling of chemical fires
• Forest Fire fighting: Lightweight 1.5 "configuration, convenient for long-distance carrying in mountainous areas

 

Application of special units

• Airport fire protection: Quick couplings + high flow rate, the critical 15 minutes for aircraft fires
• Oil platform: Anti-static design + corrosion-resistant coating, suitable for harsh offshore environments
• Emergency rescue team: Multi-interface backup, cross-regional reinforcement without obstacles

Q: What are the differences among the three diameters of 1.5 ", 2 ", and 2.5 "in actual fire extinguishing?

A: Simply put, the diameter determines the "flow rate" and "range", but it needs to match the water supply capacity:

• 1.5 ": Flow rate 2.5-4L/S, the lightest in weight, suitable for residential fires, small vehicle fires, mountainous areas, and internal floor attacks, with strong mobility.
• 2 ": Flow rate 4-6L/S, all-round player, balancing range and controllability, is the main configuration for urban fire stations and is suitable for most building fires.
• 2.5 ": Flow rate 6-8L/S, high flow rate and heavy firepower, the longest range, specially designed for industrial fires, warehouses, large factories and those requiring long-distance suppression (such as cooling of hazardous chemical tanks).

When making a selection, please give priority to the water supply capacity of the main fire engine pump.

Q: How is the flow adjusted? Can it be adjusted during the injection process?

A: Yes. The rear of the water gun is equipped with an intuitive rotary adjustment ring, allowing for stepless adjustment from "direct shot" to "atomization". During the water discharge process, the shooter can adjust with one hand at any time according to the fire scene situation without closing the water valve. For instance, when approaching the fire point, it is adjusted to an atomized state for self-protection and cooling. Once a fire source is detected, it is quickly transformed into a powerful direct strike to strike.

Q: Is special maintenance required after use?

A: Maintenance is very simple. Just remember "rinse, check and dry" :

1. Rinse: After each use, rinse the surface with clean water to prevent the residue of corrosive substances.
2. Check: Verify if the sealing ring is intact and whether it has been cut or permanently deformed. Check whether the locking mechanism operates smoothly.
3. Drying: Place it in a well-ventilated area to dry to prevent the sealing ring from aging due to long-term water immersion.
