What is the Working Principle of Exhaust fan

In General Terms

Exhaust fan blades pull the air because they run at a high rotating speed, which transfers the air to another side.

For this reason, it creates a pressure difference on both sides. The first side has low pressure and attracts more molecules. On the other side, it creates high pressure, so air will flow rapidly.

It creates a pressure difference on both sides. The first side has low pressure and attracts more molecules. On the other side, it creates high pressure, so air will flow rapidly.

Blade and radius sizes will affect the performance of the exhaust fan.

Yes, The increasing blade size and fan radius increase the air suction capacity.

What is the working principle of exhaust fan ventilation?

It works on the air exchange principle, which uses air pressure difference for ventilation.
