Abstract

The filter bag (1) has a sac formed from an air permeable filter material (2, 3), and an inlet opening (6) formed at the sac for air to be filtered. An inner cavity of the sac is divided into two chambers (9, 10), where the chamber (9) is used for coarse filtering of the air and the chamber (10) is used for fine filtering of the air that is released from the former chamber. A partition wall exhibits a density gradient, and is elastically formed.
