Abstract
Centrifugal double-mouth fan, characterized by comprising a casing that forms a flat rear face, provided with means for fixing it to any flat surface, a front face with a curved section, and two side faces orthogonal to it, in which essentially there are identical circular flanged openings opposite each other, with which correspond two centrifugal turbines equal coupled to the opposite ends of the axis of a central electric motor, whose axis is parallel to the flat rear face of the housing, and to the supply axis of the expressed lateral openings, being somewhat displaced with respect to the latter; finally having a wide opening in the said flat rear face of the housing through which the centrifuged air is expelled by the two turbines, absorbed by the corresponding lateral openings.
