Negative pressure exhaust fan/LivestockAEROPOWER VENTILATION CO.,LTD
A negative pressure in the house means the indoor pressure is lower than the outdoor pressure, which can cause air to move from outdoors to indoors. But that infiltrating air needs a pathway to do so. For air to move across the building enclosure, you need two things: a pressure difference (positive or negative) and a pathway.

When fans pull in more air than they push out of a PC case, it creates positive pressure. Negative pressure pulls more air out, often creating a vacuum effect. For optimal cooling.

As you can see, air flow and static pressure have a negative correlation. When air flow increases, static pressure decreases; and when static pressure increases, air flow decreases. The 3 points depict possible scenarios where the fan will perform.

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:
Negative Pressure Fan
Negative Pressure Ventilation (NPV), as opposed to Positive Pressure Ventilation (PPV), is the method of using a fan to pull unwanted particulates away rather than blowing them out. The Tempest EBS-16 's size and design is most effective and efficient at NPV; although, PPV may still be utilized to some degree. Know More Showing all 6 results

Set the fan inside the room, aiming out the exit door. As long as you are not pulling smoke through the fan—which would damage the fan engine—it can effectively move bad air out and pull fresh air in. This technique can negate the need to buy an electric fan. Under certain conditions, a PPV fan can be used indoors to blow bad air out.

A positive pressure PC fan is created when the total airflow in the intake fan is greater than the total airflow of the outlet fan. Positive pressure in PCs is usually preferred because it helps prevent dust particles from entering the computer system. Dust can effectively harm your computer and cause it to overheat unnecessarily.
