ABSTRACT:
A quick-change filter system including at least one base, and at least one quick-change filter having an inlet, an outlet, and a filter housing. The base includes a filter coupling part having a gas inlet stub for connection to the inlet, and a gas outlet stub for connection to the outlet. The filter housing is at least partly filled with filter material, and is connected to the inlet and the outlet. The quick-change filter further includes quick-change coupling containing the inlet and the outlet of the quick-change filter and arranged for cooperation with the filter coupling part. The base is configured for manual connection to the quick-change filter, and for automatic, gastight sealing of the gas outlet stub and the gas inlet stub when decoupling the quick-change filter from the base.
