Abstract
A fan, particularly a portable fan, includes a substantially square flat casing having a top wall with an inlet and substantially parallel side walls and front and rear walls. The front wall is provided with an open front face for the discharge of the air from a radially operating motor driven fan wheel which is positioned within the casing in an eccentric arrangement. The casing is provided with a partition wall on the rear wall side of the fan which is substantially cylindrical and the axis of the fan is located so that the clearance between the periphery of the fan and the adjacent side wall at one side is less than at the opposite side. The fan is also oriented so that its axis is positioned at a greater distance toward the curved partition wall on the closer spacing side than the opposite side so that an inwardly spiralling flow path in the form of a volute is provided from one side toward the other.
