ABSTRACT:
The invention relats to a method of filtration of a gaseous flow in which the flow is passed through at least one chamber the inlet and outlet openings of which are displaced to cause a turbulent flow projecting the particles of greater size against the walls of the chamber. At least one part of the gaseous flow is evacuated out of the chamber through a porous downstream wall which catches the finest particles. The filter has two walls (1,5) of different length connected the one to the other along every second fold (2,6). The downstream wall (5) is formed of a porous unwoven bed of fibres. The two walls (1,5) are provided with displaced openings (4,8).
