Abstract
A device for applying a coating medium to at least one partial surface of an elongated workpiece in a vacuum chamber. The device includes a housing (1) having a storage container (2) with an oblique base (3) and an air conduit opening into the base and of a deposition device that is positioned above the storage container. To ensure that the air stream exiting the vacuum chamber has a degree of purity that complies with legal requirements so that the stream can also be introduced into the working chamber, or can be used for a further coating process without any detrimental effect on the same, several sheath-type filter rods (13), which consist of borosilicate glass and are traversed by the air, are arranged downstream of the deposition device (5,7) in the direction of flow of the air removed by suction.
