Device for covering a troughs fan and troughs fan inlet unit with a covering device

摘要

The approach presented here relates to a cover device (105) for a troughs fan (100). The covering device (105) has at least one cover (125) and a filtering means (130) on. The cover (125) is formed for this purpose, in order of a bulge opening (115) of a trough (110) of the troughs fan (100) to be received the bulge opening (115) at least partly closing. The filter device (130) is formed for this purpose in order, with the cover (125) coupled to each other or can be coupled and is formed for this purpose, in order in the coupled state with the cover (125) in response to a removal of the cover (125) from the bulge opening (115), from the trough (110) to be can be inferred from.
