Abstract

1431358 Centrifugal blowers PHILIPS GLOEILAMPENFABRIEKEN NV 15 Feb 1974 [1 March 1973] 6962/74 Heading F1C In a centrifugal impeller for a suction cleaner, having blades extending to an outer periphery of a central plate 1 and equally spaced circumferentially at their outer ends, the number of blades is greater than or equal to 8,000 divided by the nominal impeller speed in revolutions per second whereby the noise frequency is raised to a value at which it is readily attenuated or is above the range of hearing, and the blades comprise long blades 5 alternating with short blades 6. The inner diameter 7 of the blades 6 is approximately midway between the inner diameter of the blades 5 and the outer diameter of the impeller. The blades on both sides of the central plate 1 are injection moulded integrally with the central plate from plastics material, and side plates 2, 3 are provided.
