Cover device for a troughs fan and troughs fan device with a cover device for a troughs fan

摘要

The present approach relates to a cover means (105) for a troughs fan. The cover means (105) has at least one cover element (125) and at least a positioning surfaces element (130) on. The cover element (125) is designed, in order to provide a troughs fan opening (115) of the depressions to cover the fan, when the cover means (105) in the troughs fan opening (115) is received. The at least one positioning surfaces element (130), transversely to the cover element (125) formed and arranged for this purpose, in order to the cover means (105) if the cover means (105) is not in the troughs fan opening (115) is received.n="20"
