摘要： A protective grille for a fan has a web structure which comprises radial webs spaced apart in a circumferential direction and coaxial circumferential webs spaced apart in a radial direction. The protective grille has at least a radial outer region and a central region around a central axis of the protective grille. An envelope surface spanned by the radial outer region and the central region is of convexly curved form in the radial outer region and is of flat form, parallel to a radial plane of the protective grille, in the central region.

摘要： A flow guiding device for use on a fan assembly with a motor-operated radial impeller rotating about an axis of rotation. The guiding device has an outer housing and an inner diffuser. A flow duct is formed between the outer housing and inner diffuser. The flow duct extends along an axial flow direction. The outer housing forms a receiving space for the integral holding of the radial impeller. The impeller borders, in the axial direction, on the inner diffuser. The impeller, during operation, takes in a flow axially and blows it out radially into the flow duct. The flow duct is adapted to deflect the flow from a radial direction into an axial direction.

摘要： The invention relates to the blades of a fan wheel. The invention particularly relates to a hollow profiled blade for a fan wheel. A hollow profiled blade according to the invention for a fan wheel is made from a planar semi-finished product and has a leading edge and a trailing edge as well as a compression side and a suction side. A hollow area is formed in the interior of the hollow profiled blade whereby the part of the planar semi-finished product forming the one side of the hollow profiled blade extends over the part of the planar semi-finished product forming the other side of the hollow profiled blade.
