• An improperly designed container ventilation could cause additional stress on the hydraulic system and thus lead, for example, to shortened service life of system filters located in the hydrosystem.

• the seat provided in the ventilation chamber for the filter sheet can be designed such that it encloses the filter sheet so as to be approximately fixed to its entire circumference at the edge. Characterized in that the filter sheet so forms a fixed part of the ventilation chamber, the assembly of the device simplifies, because when assembling only a one-piece component is to be attached to the connecting part.
