Abstract
The dust removal device comprises a fan (), a dust collection receptacle (), and a suction passage (). The dust collection receptacle () equipped with a dust filter () is located in the path of air flow () between the suction passage () and the fan (). The dust is therefore filtered out of the air stream before it reaches the fan, which prevents dust-induced wear. It is also possible to use the same fan for engine cooling as well as dust removal.
