Air Solutions offers an extensive line of fabricated multistage fans in a variety of styles and models for a wide range of air/gas services in industrial, commercial, institutional and municipal applications. The three basic designs are:

  • Standard overhung – impellers mounted on extended motor shaft
  • Four-bearing overhung – impellers mounted on shaft coupled to motor shaft
  • Four-bearing outboard – impellers mounted on shaft supported at both ends by self-aligning ball bearings, coupled to motor shaft

These fabricated multistage fans are manufactured using heavy gauge, cold-rolled sheet steel with a tensile strength of 50,000 psi, which is welded and reinforced for durability. A cast multistage fan is also available for heavy-duty process applications requiring high efficiency air delivery.
