Abstract
1,101,966. Silencing gaseous flow of fans. SINGER CO. May 23, 1966 [Feb. 1, 1966], No. 22807/66. Headings F1B and F1C. The inlet and outlet of a circumferential flow fan have associated therewith sound reducing means comprising tubes 30 with perforations 34 opening into sound absorbing cavities 28 formed in the casing 11. The cavities 28 are filled with sound-absorbing material 33 e.g. preformed sleeves of polyurethane foam. The impeller 17 is driven by an electric motor 19 fixed in a recess 21 in the casing 11.
