Lt. Kevin O'Donnell, son of Jim "Jaws" O'Donnell and coinventor of the HydroVent, prepares to put first water on the fire. The HydroVent is 7½ feet long and weighs 20 pounds with the pistol grip shutoff. The 95-gpm fog nozzle is at the tip. There is also a 95-gpm straight-stream nozzle, spike to break windows, and windowsill holder. This appliance can attach to any 1¾-inch hoseline with standard 1½-inch treads.

The first-arriving fire company can place the HydroVent nozzle in a window without entering an IDLH atmosphere. This can be a tremendous transitional strategy for successful fire control for fire departments with limited resources and personnel.

The straight-stream and fog nozzles both flow 95 gpm at 60-pound-per-square-inch tip pressure, but increased pressures deliver more gpm and increases the efficiency and speed of smoke removal with better results. The fog nozzle horizontally ventilates thousands of cubic feet of smoke per minute while the straight-stream nozzle simultaneously applies water to the interior fire room, dramatically lowering the temperature, making it safer for firefighters, and increasing the survivability and rescue profile for victims.

The HydroVent also comes with a piercing nozzle tip, which connects at midpipe for use on attic fires and concealed spaces. This is a total of three nozzles and a shutoff, making it a value for fire department with limited budgets.

The HydroVent is the only nozzle on the market that hydraulically ventilates thousands of cubic feet of smoke per minute while simultaneously applying 95 gpm of water into the interior of the fire room. Ventilation and extinguishment start as soon as you open the nozzle. Note the smoke conditions around the containers and the color of the smoke being ventilated out the window-from dark to white (steam), indicating the water is extinguishing the fire. This whole evolution took less than two minutes. The HydroVent was the only hoseline operating. (Photo by Nick Schmitt.)
