A positive pressure ventilation fan (or PPV) is positioned at the entry to push air into the space, creating pressure that moves heat, smoke or contaminated air out of an exit point. The Super Vac PPV fan features a chopper blade, which moves a wider mass of air, ideal for:

• Fire operations
• General and large area ventilation
• Vehicle extrications
  
  
  
  

A negative pressure ventilation blower (a Smoke Ejector or Blower/ Exhauster) is positioned at an exit point to pull air away from the space, creating negative pressure to remove the heat, smoke or contaminated air. Many of these fans feature Super Vac’s patented spiral blade that creates a more concise, direct air flow, ideal for:

• Confined space ventilation
• Ducted ventilation
• Cooling machines or work areas
• Positive pressure scenarios, when positive side of fan is used

Super Vac offers a number of other products that can further enhance conditions. Ventilation saws and smoke curtains control airflow into a structure, while select accessories create light, foam, mist and even heat to further control the environment and aid in crews’ rescue efforts.
