Abstract

1419591 Centrifugal fans L T G LUFTTECHNISCHE GmbH 28 Feb 1973 [3 March 1972 31 Oct 1972] 9811/73 Heading F1C A centrifugal fan comprises an approximately parallel piped casing having two square or oblong side walls 12, (13), Fig. 2, (not shown), and flow peripheral plane walls 24, 25, 26 forming a tangent to an imaginary scroll 22, the fourth side wall being substantially completely open to define an outlet 29. The fan has an axial inlet (20) and rearwardly curved impeller blades 16. Again, Fig. 3 (not shown), the middle wall 25 may have a spirally bent shape (25') or may be bent into approximately circular shape. Specific relative dimensions are given.
