Abstract

A filtration device, in particular a disposable filtration device, has a flow path in which a filter element and an integrated flow reducer are arranged one behind the other. The flow reducer is adapted to be brought to a first operating position, which permits a defined first volume flow rate, and at least to a second operating position, which permits a defined second volume flow rate which is smaller than the first volume flow rate.
