Jet Nozzle Water Spray Nozzle Fire Fighting Water Gun - Q&A

 

 

1. Q: What is the CA-Fire Jet Nozzle (Fire Fighting Water Gun)?

 

A: The CA-Fire Jet Nozzle (Model: QZG3.5/7.5) is a specialized jet-type fire fighting tool engineered for long-range, high-efficiency fire suppression. Unlike standard spray nozzles that prioritize wide coverage, this nozzle focuses on delivering a concentrated water jet to reach distant fires-making it ideal for scenarios where firefighters need to stay at a safe distance from heat or hazardous flames, such as warehouse storage racks, tall industrial equipment, or outdoor stacked cargo fires.

 

Crafted from aircraft-grade aluminum alloy 6061 T6 (with anodized anti-corrosion treatment to resist humidity and mild chemicals), it operates at a moderate 0.35MPa working pressure-lower than high-pressure nozzles, which reduces operator fatigue during extended use. Despite its low pressure, it delivers impressive performance: a 7.5L/S flow rate, a minimum 28m flow distance (jet mode), and a large ≥45mm orifice that ensures consistent water output without clogging. Equipped with 1.5"/2.5" couplings (compatible with most global fire hoses) and weighing only 1.5kg, it can be easily handled by a single operator-suitable for both professional fire departments and on-site emergency teams in commercial/industrial facilities.

 

2. Q: What are the core advantages of this jet nozzle?

 

A: This jet nozzle stands out with 4 targeted strengths, tailored to long-range fire safety needs and operator comfort-avoiding overlap with high-pressure or wide-coverage nozzles:

Low-Pressure Design for Extended Use: Operating at 0.35MPa (50.8 psi), it generates far less recoil than high-pressure models (e.g., 0.7MPa nozzles). This means operators can hold it steadily for 15+ minutes (critical for large fires) without arm fatigue, while the low pressure also reduces wear on fire hoses and pipelines.

Long-Range Jet Performance: With a minimum 28m flow distance in jet mode, it lets firefighters suppress fires from a safe perimeter-ideal for scenarios like burning chemical barrels or tall warehouse shelves, where close-range operation risks injury. The concentrated water jet also penetrates thick smoke to reach the fire core faster.

Lightweight & Durable Aluminum Build: Weighing just 1.5kg (3.3lbs), it is 40% lighter than steel jet nozzles-easy to carry up ladders or through narrow industrial corridors. The anodized aluminum surface resists rust and degradation from outdoor exposure, ensuring a service life of over 8 years in harsh environments (e.g., manufacturing plants with dust or fumes).

4-in-1 Spray Modes for Versatility: By rotating the gun head protective cover, it switches between 4 modes to adapt to different fires: ① Jet (long-range for distant fires); ② Blooming flow (wide coverage for small spreading fires); ③ Mist (fine droplets for electrical or flammable liquid fires); ④ High-pressure flushing (clears debris from blocked hoses). This eliminates the need to carry multiple nozzles for different scenarios.

4. Frequently Asked Questions

 

Q: Why is the working pressure only 0.35MPa? Won't that reduce fire suppression efficiency?
A: The 0.35MPa pressure is intentionally calibrated for balance: it's low enough to minimize recoil and operator fatigue, but high enough to deliver a 28m jet (sufficient for most industrial/commercial fire scenarios). For reference, standard warehouse fires only require 20–30m range-this nozzle exceeds that while keeping operation safe. If you need higher pressure for extreme scenarios (e.g., 40m+ range), we offer a custom 0.5MPa version (MOQ: 50 units).

Q: Can this nozzle be used with foam concentrate for Class B fires?
A: Yes. It works seamlessly with a foam expansion tube (sold separately) to convert water into fire-suppressant foam. The large ≥45mm orifice ensures smooth foam flow without blockage, making it suitable for Class B fires (e.g., oil spills) in addition to Class A (solid combustible) fires.

Q: Is the 1.5"/2.5" coupling compatible with my local fire hoses (e.g., Storz in Europe, NH in the U.S.)?
A: The standard couplings fit most universal fire hoses, but we offer custom coupling replacements (Storz, NH, BS) with no extra cost. Simply specify your local standard when ordering-lead time will be extended by 3–5 days to adjust the coupling design.

Q: How do I maintain the nozzle to prevent performance loss?
A: Maintenance is simple: 1) After use, flush the nozzle with clean water to remove debris from the filter and orifice; 2) Dry it thoroughly and store in a ventilated room (avoid direct sunlight, which degrades the silicone head); 3) Inspect the handle and coupling quarterly-replace the silicone head if it cracks (spare parts are available for purchase).

 

5. Q: Why choose CA-Fire Protection Co., Ltd. for this jet nozzle?
