Abstract

In a method of stabilizing the pressure of a centrifugal fan comprising an impeller (1) mounted in a fan casing (4), said impeller being shielded by a shroud ring (2) on the inlet side said shroud ring extending to the mouth of an inlet cone (3) of the fan with a clearance between shroud ring and inlet cone, a flow recirculating in the region between the shroud ring and the side plate (5) of the fan casing on the inlet side is directed towards a discharge section (7) of the fan by eliminating the revolution symmetry in said region on the inlet side by stabilizer means. In an apparatus for stabilizing the pressure of the fan the stabilizer means are provided in the region between the shroud ring and the side plate of the fan casing on the inlet side.
