"FIREJECTOR" - A FIRE FIGHTING EQUIPMENT INNOVATION
Firejector set up with a test tunnel for evaluation. Flames in - mist out. Firejector demonstrates the principal of entrainment during preliminary testing.

FREQUENTLY ASKED QUESTIONS:
Question:
How is this equipment and process different from conventional fire attack with a regular fog nozzle?Answer:
The Firejector's entrainment action rapidly removes large volumes of heat, smoke and gasses from within the structure. The water mist droplets produced by the Firejector are smaller than with a fog nozzle - small enough to stay suspended in the air, absorbing heat and extinguishing fire in areas that may not be reached by a standard nozzle. The mist droplets cause minimal, if any water damage inside the structure.Question:
What would happen to victims inside the structure when the Firejector is activated?Answer:
The Firejector can remove toxic gasses and smoke from an average room in less than 30 seconds; locating victims is faster with better visibility. The positive pressure unit entrains moist, fresh air into the structure. The survival conditions in a confined space improve rapidly for a victim in this situation.Question:
How could the Firejector help with fire prevention?Answers:
- A build up of explosive or toxic gasses, dust or heat can be controlled and/or removed using the entrainment function of Firejector long before an explosion or toxic effects occur.
- The system can be used to extinguish smoldering embers in an inaccessible location, reduce heat build-up in a rafted roof, and remove the danger of fire spreading or starting new fires from sparks and brands.
- The ultra fine mist technology can be used as an alternative to a conventional sprinkler system in fire prevention applications.
Question:
How do water droplets entrain flames and smoke?Answer:
Minute water droplets moving at high speed entrain (push and pull) air and gasses within the droplet flow pattern. The volume and speed of the entrained gasses is related to the speed, size and configuration of the water droplet spray pattern. A secondary force is created as the minute water droplets absorb heat and expand. When the Firejector is installed as an extraction unit the rapid expansion is occurring as the heat mist mixture is forced out of the structure. Multiple fine mist nozzles in the Firejector unit are positioned and directed in a configuration to maximize the powers of entrainment and expansion.Preliminary Statistics Based on Early Tests:
The estimated volume of expelled flames, smoke, etc. is 15,000 cubic feet per minute (cfpm) using the extraction unit. This volume increases when the positive pressure unit forces approx. 15,000 cfpm of fine mist spray into the burning structure.Water usage will depend upon available water pressure and the application. As an example:
One unit at 100 psi: 40 gallons per minute
at 200 psi: 25 gallons per minute
at 1000 psi: 10 gallons per minute
