Another high pressure in-line fan
developed by NISCO Fan Co. is its Mixed Flow Fan. Mixed Flow fans are
an excellent choice for return air, supply, or general ventilation
applications where low sound is critical. As compared to similarly
sized tubular centrifugals and vane axials, a mixed flow fan will be
5-20 dB quieter! In addition, the mixed flow wheel is extremely
efficient and will cut down on operating expenses.
