Abstract

A radial blower, in particular, for a breathing apparatus, has a blower housing with a central, axial intake opening and a radial or approximately tangential outlet opening as well as a motor-driven radial blower wheel arranged axially between the intake opening and the outlet opening. The radial blower wheel has a cover disk at the axial side facing the outlet opening with such a large diameter that between the outer circumference of the cover disk and an inner circumferential surface of the housing a constricted annular flow gap for the medium flowing through the radial blower wheel in the direction toward the outlet opening is formed.
