A fan assembly provides for the compact and efficient movement of ambient air in areas requiring very low noise generation. In this new configuration, stationary turning vanes are placed at the air inlet followed by a sound cell, axial discharge fan and short axial (vaned) diffuser splitter sections. The stationary turning vanes induce a predetermined air rotation which provides a smooth rotating air flow into the rotating fan blades. The stationary turning vanes also block radiated noise from discharge through the air inlet and support the fan motor. Th...
A low noise axial flow fan assembly for suppling fluid to a fluid distribution system which comprises: an external duct having fluid inlet and discharge means; turning vane means within said duct adjacent to said inlet means for imparting a swirl velocity component to said fluid discharing from said turning vanes; fan means spaced from said turning vane means for drawing said fluid through said inlet means and exiting said fluid out said exit means, said fan means having rotating blades configured to redirect said swirl velocity component of said fluid i...
