Abstract

The invention relates to a preseparator means for a dust collector. The preseparator means comprises: at least two dust separation units (2A, 2B), each adapted to receive a gas flow carrying dust particles at an inlet (3A, 3B), separating and collecting at least a part of the dust particles from the gas, and emitting the gas thus treated at an outlet (4A, 4B); switching means (8) adapted to switch the operation between said separation units (2A, 2B), so that each separation unit is shut off from the gas flow intermittently, in order to allow removal of collected dust particles from the shut off separation unit, while the other separation unit is in operation. The invention enables continuous operation of the preseparator means.
