DEVICE FOR CLEANED AIR PROVISION

摘要

The invention relates to a device (3) for providing a flow of cleaned air to an apparatus (1). The device comprises a bent duct (29) having a first end (31) arranged to be positioned outside the apparatus and a second end (33) arranged to be positioned inside the apparatus, and a filter (43). Air from outside of the apparatus is conveyed through the filter for cleaning, through the duct and into the apparatus, and a cross section of the duct orthogonal to a longitudinal centre axis (L) of the same varies. More particularly the cross section at the first end differs from the cross section at the second end in that the cross section at the second end (33) has more corners than the cross section at the first end (31). The device is characterized in that the duct is bent in such a way that a direction of the longitudinal centre axis (L) at the first end (31) is angled in relation to a direction of the longitudinal centre axis at the second end (32), and in that the filter is arranged upstream the bend, relative to the flow of cleaned air.
