Abstract
In a vehicle air is compressed for being used in the brake system of the vehicle, for instance. In the compressor, used for the compression, the air is contaminated with oil and solid particles. In order to be relieved from these particles, before the air is conveyed through a drying filter, the compressed is brought to rotation by means of a rotating member in a centrifugal separator. The rotating member may advantageously include a pile of conical separation discs forming flow passages between each other for the compressed air to be cleaned. By means of an efficient cleaning of the compressed air from particles the life time of the drying filter may be increased.
