Abstract:
Method for compressing atmospheric air using a centrifugal or axial compressor (1), comprising the steps of:subjecting air at a natural temperature to a filtration stage (5), the filtration stage (5) comprising bag-filter elements (9) with a filter medium (11) made up of synthetic fibres with a density which increases in a direction (Fâ€²) of flow of the air through this medium, the air being introduced into the bag-filter elements (9) at the air's natural temperature; and establishing a flow rate of the air passing through each bag-filter element (9) at a value which corresponds to a mean speed of filtration through the medium (11) of between 0.1 and 0.4 m/s.
