Pressure
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. Besides, a pressure difference will be formed between the inside and outside lungs. So that fresh air is pressed into the lungs. The fan from the inlet to the air inlet belongs to the negative pressure area.
