In fact, it has positive pressure and negative pressure. Positive pressure refers to the state of a gas at a pressure higher than normal pressure. For example, when inflate bicycle or car tires, a positive pressure present at the outlet port of the inflator or pump. The fan outlet goes to the air supply outlet, which is a positive pressure zone.
Negative pressure is a state where the gas pressure is lower than normal pressure. The use of negative pressure is very common. While people often make a certain part of the space negative pressure. Thus they can use the such pressure to work for us. For example, when a person breathes, the lungs are in a state of expansion. Then there will be negative pressure.
