Abstract

1,079,331. Centrifugal fans &c. JAMES HOWDEN & CO. Ltd. April 12, 1965 [April 15, 1964], No. 15565/64. Heading F1C. Two single-inlet impellers 10, 11, Fig. 2, on a common shaft 12 are housed in separate volute casings 13, 14, with a common inlet duct 15 for the two casings filling the space between the casings. Frusto-conical inwardly-tapering guide conduits 18, 19 on opposite sides of the inlet duct 15 project into the respective casings to deliver fluid to the impeller eyes. A splitter plate to divide the flow, and spin vanes may be provided in the inlet duct 15.
