Abstract

A fan rotor, in particular for a tangential fan, comprises
   two transverse terminal elements (12), substantially perpendicular to the axis of rotation of the rotor;
   a plurality of longitudinal blades (16) arranged circumferentially about the axis of rotation of the fan rotor, parallel both to each other and to the axis, and which extend longitudinally between the transverse terminal elements (12); and in which
   the transverse terminal elements (12) are made of metal and the blades (16) are moulded of a plastics material and fixed to the periphery of the transverse terminal elements (12).
