In a centrifugal separator and method for cleaning of gas containing solid and liquid impurities. A stationary casing encloses a separation space through which gas flows. An inlet channel extends to the separation space and forms an inlet for the gas to be cleaned. A rotating member is provided in the separation space downstream the inlet and rotates about an axis of rotation. The rotating member comprises a number of separation discs and brings the gas to rotate for separating by means of centrifugal forces a main part of the impurities from the gas. A gas outlet channel is provided downstream the rotating member for discharging the cleaned gas. A first outlet is provided for discharging the impurities. A supply member is configured to permit the supply of a separation aid humidifying the particles, which aid is in the form of an aerosol, to the gas to be cleaned.

The invention relates to a filter mat, which is used in applications where it filters the flows of contaminated air that pass through it. In such mats, there are points where aerosols collect. This is disadvantageous as it lowers the efficiency of the mat. The present invention overcomes this by having, at these points, wicks () that absorb said collections.
