FAQ

 

Q1: How should these four flow rates (115/230/360/475 LPM) be selected in actual firefighting?
A: Choose based on the size and type of the fire:

 

  • 115LPM: Suitable for initial electrical fires, small vehicle fires, and initial indoor fire points. The water volume is precisely controlled, minimizing water damage.
  • 230LPM: General model, suitable for residential building fires, commercial building fires, and training purposes. It balances the fire suppression effect with water usage efficiency.
  • 360LPM: Suitable for medium-sized fires in factories and warehouses, or for places that require rapid cooling and smoke exhaust.
  • 475LPM: Maximum flow suppression, suitable for severe fire scenes in chemical plants, oil fires, etc. where a large amount of water is required for coverage.


Q2: When is the Flush function used?
A: There are three main scenarios:

 

  1. After extinguishing the fire, clean the inside of the spray gun to prevent any impurities from remaining and blocking the nozzle.
  2. When low-pressure water is needed at the site (such as for cleaning equipment or diluting chemicals)
  3. Demonstrating the effect of low-pressure water flow during training sessions


Q3: How to choose the size for the imported products (1.5 inches, 2 inches, 2.5 inches)?
A: Select based on the inner diameter of your water hose:

 

  • 1.5 inches: Compatible with 40mm hose, lightweight and flexible, suitable for indoor and confined spaces
  • 2 inches: Compatible with 50mm hose, the most commonly used specification, balancing flow rate and portability
  • 2.5 inches: Compatible with 65mm hose, suitable for high-flow requirements, ideal for vehicle-mounted and fixed fire protection systems.

 

Q4: How are the DC and spray modes used in conjunction in actual combat situations?
A: Typical tactical combination:

 

  • Attack phase: First, use the spray mode with a 120° wide-angle to cool down and ventilate the area, creating a passage for advance and protecting the firefighters.
  • Suppression stage: Switch to direct current mode. Fire a 40-meter-long direct jet at the root of the fire source to achieve concentrated water pressure suppression.
  • Cleaning stage: Switch back to the spray mode and cover the area extensively to prevent re-ignition.
  • Cover and retreat: The spray mode creates a water curtain to protect personnel during the evacuation.


Q5: What is the coverage area when the maximum spray angle is 120° in actual use?
A: At a pressure of 6 bar, when the distance is 10 meters, a 120° spray can cover an area approximately 21 meters wide; when the distance is 20 meters, the coverage width can reach about 35 meters. It is very suitable for quickly establishing fire isolation belts and cooling large groups of people.


Q6: What are the differences between OEM and ODM? We would like to print our company's logo.
A:

  • OEM (OEM): We will manufacture according to your design specifications, including the color of the casing, the logo of the unit, and the packaging labels, etc. 
  • ODM (Design and Manufacturing): We will customize the product according to your specific requirements, such as adding pressure gauges, changing gear settings, providing special interfaces, etc. Detailed technical requirements must be provided. 
  • Printing only the logo is included in the OEM service.


Q7: How do we determine how many units we need to purchase?
A: Recommended configuration ratio:

 

  • Main battle fire engine: 4 to 6 nozzles (with different flow rates) each vehicle
  • Command vehicle/Logistics vehicle: 2-3 spares per vehicle
  • Key guarded units: Calculate at 1 unit per 1,000 square meters.
  • Training purpose: Equip 1 set for every 5 participants.
