ABSTRACT:
A centrifugal fan including a fan wheel and a driveshaft for rotating the wheel in a housing. The fan wheel has an axial center and outer edge portions around the radially outermost extremities. The housing is formed of right and left unitary housing halves of the same size and shape. The housing halves each form a sidewall of the housing and a portion of a circumferential wall of the housing. The housing halves are joined directly to one another to form the housing. The housing has a suction inlet in one of the right and left housing halves at the axial center of the wheel and a fan outlet formed by the housing. The outlet has a center line that is located generally on a radius extending from the axial center of the fan wheel. A chamber for the fan wheel is formed in the housing. A baffle is rigidly connected to the housing and is located in the housing adjacent the side of the fan outlet towards which the fan wheel rotates. The baffle extends into the chamber and terminates at a point outside but adjacent to the path of rotation of outer edge portions of the fan wheel. The baffle is arranged at a substantially acute angle to the center line of the outlet.
