Plenum Fans
Chicago's Plenum Fan offers a practical, economical design alternative for air handling and conditioning systems. It features an unhoused true airfoil bladed wheel that installs directly within the plenum, thereby eliminating the downstream discharge. The fan can be installed either horizontally or vertically.

Plenum Fan Applications
Without the conventional scroll, the Plenum Fan provides the required performance in less space. It is therefore ideal for retrofit applications where system performance needs to be expanded and more space is not available. For either supply fan, return fan or exhaust fan applications, rely on the performance and durability of Chicago Airfoil Plenum Fans.
