The Airotor blower wheel is made in diameters from 1 1/2” to 9 13/32” inches and in a large ranges of widths in each diameter. Airotors are made with a simple four piece construction consisting of a bladestrip tightly spun into a front ring and a heavily ribbed back place and a hub which is spun into the back plate. Standard construction is of galvanized steel. Trueness and static balance are held to close tolerances.
While ordering, one should specify the complete catalogue number, rotation (determined by viewing the closed side of the wheel), the hub position (inside or outside) and the size of the bore.
