Abstract

This invention relates to a fan for gas boilers with proof combustion, comprising a centrifuge rotor housed inside a spiral made up of two die-cast aluminum semi-shells (1,2), of which one (1) is externally provided with a bracket (5) for the support and centering of the motor-rotor assembly made from one die cast piece together with its semi-shell (1).
