How does a breather work?

When the vehicle is moving, airflow across the open end of the tube creates suction (a “draught” or draft) that pulls gases out of the crankcase. To prevent a vacuum being created, the blow-by gases are replaced by fresh air using a device called a breather. The breather is often located in the oil cap.

What material is filled in breather of transformer?

Many companies that operate in the power generation sector attach silica gel breathers to the conservators that are used in oil-filled transformers. The main purpose of this addition is to remove moisture or water vapor content from the air used by the transformer to breathe.
