Mist Fire Fighting SystemJet Firefogging System Series

Optimized Mist for the Greatest Fire Fighting Performance.

Excellent for People and the Environment, with Respect to Preventing water Damage

The Jet Firefogging System Series is a mist fire fighting system developed by Ashimori Industry Co., Ltd., and has superior cost-performance characteristics.
With the optimized mist (droplet size of the mist and the water content) produced by the Jet Firefogging System, fire fighting is carried out effectively due to 1) cooling effects, 2) suffocating effects, and 3) dilution effects. With the optimization of the mist, the water-based fire fighting capacity is drawn out to the upper limit; the amount of water used to fight the fire is extremely small compared to conventional large-scale water discharge fire fighting, and it is also possible to fight class B fires.
Of course, this innovative system “prevents water damage”, and achieves ecological fire fighting that is “highly people- and environment-friendly”, non-toxic fire fighting that does not use carbon dioxide or halogens.
Furthermore, the Jet Firefogging System has a lightweight, compact design that meets the functional requirements for dedicated use in the early stages of fire fighting on light four-wheel fire trucks, and is easily loaded onto rescue vehicles or pump trucks.

1. Optimized Mist with Significant Fire Fighting Capability

  • If the mist used for fighting the fire is too large, the smaller surface area will be inadequate for absorbing the energy of the fire. Conversely if it is too small, it will be carried away on the air currents produced by the fire and will not be able to reach the flames.
  • There is a size of the mist that is the most effective in fighting the fire, and it is this optimized mist that is produced by the Jet Firefogging System.

2. With One-Step Start-Up and Simple Operation, a Rapid Response to Fires is Possible

  • Start-up is only pushing a button, so fires can be fought immediately and the power can be utilized particularly in the initial stage of fighting the fire.
  • The rapid response to the fire using the optimized mist means that the space occupied by the fire is effectively cooled to prevent any flashover.

3. Designed to Prevent Water Damage, can also Respond to Class B Fires

  • The amount of water needed to achieve the cooling efficiency and suffocating efficiency of the optimized mist is on the order of from 1/10 to 1/20 that of conventional systems.
  • Since the water is in the form of an optimized mist, it becomes possible to respond to oil fires.

4. Fires can be Fought in a People- and Earth-friendly Way

  • Non-toxic, doesn't use carbon dioxide or halogens. Fires can be fought with superb people- and environmental-friendliness.

5. The Lightweight and Compact Design is Highly Mobile, and a Broad Range of Applications are Possible

  • Comes in a lightweight, compact body. Simple to load onto rescue vehicles and pump trucks.
