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.

There is provided a dust discharge outlet (6) for a separator device (1) arranged for separating particles contained in an air stream. The dust discharge outlet (6) comprises a discharge opening (7) and to which dust discharge outlet (6) a substantially airtight collecting bag (8) is receivable. A passageway (7,11) for discharging dust particles into the collecting bag (8) is formed by the discharge opening (7) and a portion (11) of the receivable collecting bag (8). A closure body (10) is arranged in the passageway (7,11) for sealing against the laterally contracted collecting bag (8) at a negative pressure in the passageway (7,11). There is further disclosed a separator device comprising the dust discharge outlet (6), and a method for closing the passageway (7,11).
