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.

The negative pressure fan exhausts air to lower the indoor air pressure, generating a negative pressure zone. The air enters the chamber due to the pressure difference. A positive pressure fan works in reverse of a negative pressure fan. The negative pressure fan is used for ventilation, smoke, and odour. A positive pressure blower directs air.
Push Pull Negative Pressure Fan
A negative pressure environment is created by using fans for exhaust air and louvers or doors for supply air. When the exhaust fans are on, they create a vacuum in the building which pulls air in through the supply air openings.

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.

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.

Picture
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:

2. Exhaust fans. Like combustion appliances, exhaust fans can remove too much air and cause negative air pressure. This can be dangerous, especially in a restaurant kitchen. Negative pressure can cause backdrafting of cooking appliances, woodburning stoves, and fireplaces, leading to a buildup of deadly fumes including carbon monoxide. Learn more:

When the kitchen and bathroom exhaust fans are turned on or the clothes dryer is started, a slight negative pressure is generated (yep-check out our article on heat pump dryers, where we disclose that regular dryers dump about 200 cfm of conditioned air outside!).
Feature
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.
