Breathers are also known as tank vents. The Breather function is like a place for air circulation in the tank so that no air is trapped in it during the fuel filling process. To ensure that the air entering the tank is clean and dry, an Air Breather Filter that uses Desiccant is used.

A good desiccant air breather filter has the ability to circulate large volumes of air and can dry and capture dust particles in the air so that the air entering the tank is clean and dry.
