Abstract

A ventilator has a motor-driven fan with a hub and fan blades rotating on a spindle within a housing. The housing has an outer frame which is linked to the spindle support by ribs (22). The ribs especially have a cambered cross-sectional profiles which deflect oncoming air, thereby optimizing the angle of attack of the fan blades to the oncoming air flow.
