Air-feed system to radial fan - has opposite converging guide fins with adjacent edges inside fan opening

摘要

This air guide system comprises two or more opposite guide fins (4, 5), symmetrically situated in relation to the plane containing the fan axis (3). The edges adjacent to the fan are inside its opening and from these edges they diverge outwards from the plane (3). The fins can form part of a partly-tapering annular sheet-metal section. In the outwards direction, they can extend beyond the outside of the fan. USE/ADVANTAGE - In a large kitchen etc., giving even distribution of intake air.
