Abstract
1,008,734. Centrifugal blowers. PLESSEY CO. Ltd. Feb. 2, 1962 [Feb. 20, 1961], No. 6125/61. Heading F1C. In a centrifugal blower a single wheel is surrounded by a housing which is divided by one or more walls perpendicular to the blower axis, and each of the parts is formed as a volute complete in itself with its own cut-off point, the outlets of the individual parts being angularly displaced relative to each other about the blower axis. An undivided rotor having a central inlet 2 and a set of undivided blades 3 is mounted on a shaft 1 in a housing consisting of two identical volute shells 4 and 5 coaxially secured with their outlets 6, 7 displaced by 90 degrees. The abutting walls form a central partition which, because of the axial inlet air velocity and the guiding effect of the blower wheel backplate, causes approximately 55% of the air to be delivered to the outlet 6. The distribution of the air to the outlets 6, 7 can be varied by altering the relative axial widths of the outlet volutes. More than two outlets can be provided, each having its own volute and separated from the others by a partition.
