Available in nominal diameter sizes of 50, 60, 70,.84, 100 and 120cm and with one single hub used for the entire range, the Uniax axial flow fan impeller has size variations that are obtained by differing blade size. With each basic fan size, output can be varied by varying the number of blades fitted. This hub can be fitted with three, four, six, eight or 12 blades.
Air flows up to 60,000 cfm can be created apparently against pressures up to 7in. of water.
The pitch angle of all blades can be simultaneously and accurately varied between plus or minus 8deg by the rotation of one half of the hub counter to the other half, without dismantling, this giving variations of output.
It may also be fitted into any axial flow fan requiring this output versatility. As an impeller replacement it is mounted on the fan shaft or directly onto the fan motor shaft, depending on the fan arrangement, and is enclosed within a short cylindrical casing.
Alternatively, the Uniax can be incorporated directly into dryers, heaters, air handling units, diesel engines, compressors, machine tools, etc, where a flow or circulation of air is required, or to provide air cooling.
In this installation the Uniax is incorporated directly into the machine itself and mounted either on its own special shaft, on a motor shaft or on an extension of a machine's integral shaft provided its rotation is of a suitable speed.
