Direct Drive Airfoil Plug Fan
Chicago’s direct drive airfoil plug fan offers a compact economical alternative to belt drive plug fans. For retrofit installations, the compact direct drive configuration allows greater system flexibility. When coupled with a variable frequency drive, performance is no longer limited to sycronous motor speeds. Direct drive simplicity converts to lower initial cost and less operating expense, as there are no fan shafts, bearings, belts or guards to maintain.
Plug fans utilize Chicago’s quiet, efficient airfoil wheel with hyperbolic inlet cone. Exceptional rigidity is afforded by the heavy steel panel with flanged edges and gusseted motor base. Plug fans are designed for horizontal or vertical installation.
Chicago’s direct drive line consists of plug fan sizes from 12-1/4 to 30 and static pressures to 12”. Directdrive temperature maximum is typically limited to 180°F,or higher when equipped with factory cooling wheel and insulated plug panels. For elevated temperatures, ask about Chicago’s belt drive or direct coupled fans. The versatile plug fan design allows for use of either C-face or foot mounted motors. Fans are also available with steel housing, backward inclined wheels or other factory modifications
