System, comprising a support frame, a filter element fixed in it, as well as at least two fixing devices

摘要

The system has a support frame (1) comprising frame parts (2), and a filter element fixed to the frame. The frame parts are designed with L-shaped cross-section, where an outer contour of the filter element is designed such that the filter element is fixed against the frame over a fixing device (8). The fixing device has an elastically designed fixing element. The fixing element is moved from fixing position in which the filter element is fixed in the frame to a direction of a side bracket (4), where automatic back displacement is provided in the fixing position based on return force.
