Abstract
A fan unit (), to be attached to a filter frame () of a filter fan, consisting of a housing with a cylindrical housing rim, an inlet opening (), an outflow opening () and at least one protective grid which covers one of both of the openings, and one fan () attached to the housing via a motor mount () which conveys the air in at least the axial direction. The design enabling the manufacture of a more compact fan unit in an easier and more cost-effective manner, which provides high efficiency and can be installed as a suction as well as a blowing fan unit in the filter fan, and is easy to dismount for the maintenance of the filter fan. This is attained in that the fan unit housing is divided perpendicularly with respect to the axis (X-X) of the fan () in the region of the housing rim () into two housing parts, one forming a motor bracket () and the other forming an air inlet part (), which are detachably connected to one another, whereby the motor bracket () as well as the air inlet part () each integrally form a protective grid structure ().
