The atmospheric air possibly passes through a droplet separator (3) then passes through one or more filtration stages (5, 6). For the or the first filtration stage (5), use is made of bag-filter elements the filter medium of which is made up of synthetic fibers with a density which increases in the direction of flow of the air through this medium. The air is introduced thereinto at its natural temperature when this is between -20° C. and +5° C. approximately, outside of periods of freezing fog, supercooled rain or snow. Application to the compression of air intended to be distilled or to a gas turbine of the industrial type.
