Abstract

The invention relates to a fan unit () for mobile use for ventilating an area in which it is deployed, in particular for circulating fresh air in areas contaminated by smoke or gases, which comprises a main frame (), having a lifting frame () mounted thereon and an axial fan (). A first pivot arrangement () for the lifting frame () is disposed on the one hand in the region of a frame part () extending up from a base frame () and on the other hand in a first end region () of the lifting frame () facing the frame part (). The lifting frame () can be adjusted in terms of its vertical distance from the base frame () from a non-operating position lying closer thereto into a raised deployment position. A second pivot arrangement () is disposed on the lifting frame () about which a support frame () is mounted so as to be pivotable in terms of its relative position with respect to the base frame (). The axial fan () is retained on the lifting frame () with the support frame () connected in between.
