  • Page 12: How To Use Positive Pressure Ventilation

    OSITIVE RESSURE ENTILATION HOW TO USE POSITIVE PRESSURE VENTILATION PPV The Basics Positive pressure ventilation (PPV) is a powerful tool for fire fighting but, like a double- edged sword, it can cut both ways. Training and careful planning are essential if PPV is going to work to its full potential.
  • Page 13: Placement

    ENTRY OLUTIONS Placement Avoid operating the fan too close to a structure's opening. Position the fan 8 to 15 feet from an average 3' x 7' door. It is best to err on the side of placing the fan too far from the door to prevent the situation shown in Figure 22.

    OSITIVE RESSURE ENTILATION effective. The air will take the path of least resistance. If you have a lot of windows and doors open the air will most likely take a path that isn’t the one you want to remove the smoke. Ground Debris Pickup / Maximum Air Volume This positive pressure fan is designed to run with the legs partially extended.
  • Page 15: Common Questions About Positive Pressure

    ENTRY OLUTIONS COMMON QUESTIONS ABOUT POSITIVE PRESSURE Why positive instead of negative pressure ventilation? Stand on the suction side of a fan -- there's not much happening. Now stand downwind and note the difference. The same thing happens in a structure just as dramatically: with positive pressure, smoke and heat come blasting out of the structure and visibility improves in a matter of seconds.
  • Page 16: Fan Comparison Methods

    OSITIVE RESSURE ENTILATION Positive pressure is also very useful to pressurize areas of a structure to prevent or slow down fire spread into uninvolved areas. We stopped a fire in a 6 unit apartment building using this technique with three fans pressurizing the central foyer. We just opened the door to the apartments that we wanted pressurized.
  • Page 17: Warranty

    Be sure to balance the propeller before placing it back on the fan to ensure that the fan does not walk. Significant damage which penetrates the fiberglass/kevlar coating may require evaluation and repair by Ventry Solutions. Frame Maintenance Wipe down the frame to remove dirt and grease buildup The rubber leg bottoms (jumbo crutch tips) will need to be inspected for wear.
  • Page 18: Leg Movement Obstructed

    RESSURE ENTILATION Bent Frame: Ventry Solutions’ positive pressure fan is by no means symmetrical. If you position yourself behind the fan on its right side, the closest leg should be angled several degrees ahead of the left leg. This same leg also leans out more than the left leg does. These are design aspects engineered into the fan to increase the stability and to prevent walking.
