Abstract

A housing for a fan or blower, in particular an axial fan, includes a wall ring (2) having an inlet nozzle section (3), an outer diffuser (6) having an inlet flow opening (7) and an outlet flow opening (8), and a holder for an electric motor (9) of the fan. The holder is arranged in an inner space of the housing. The outer diffuser (6) is formed by at least two partial ring sections that are connected to the outer circumferential surface via mechanical connection elements. The holder includes several struts (14) that are fastened to an inner circumferential surface of the outer diffuser (6) by one end, are circumferentially spaced apart, and are fastened in the edge region of the inlet flow opening (7). The struts can be installed by their other end to a motor flange (16) of the motor housing (17) of the electric motor (9).
