Abstract

A filter device has a housing in the shape of a tubular section, with at least two chambers separated from one another by membranes, and with at least one connection for each flow chamber. The device has two filter caps, with one of each of the filter caps being located on each of the two end regions of the housing, and connected directly or indirectly thereto. All connections for the flow chambers are positioned on the tubular section in order to avoid tolerance variations that frequently occur during installation of the filter device.
