Look at the direct drive plenum fans manufactured by ziehl abegg a german company that manufactures direct drive plenum fans with the highest efficiency and lowest sound levels in the industry.
Direct drive plenum fans.
Equipped with a gusseted mounting panel they are mounted directly to the plenum wall separating the motor and drive components from the process air.

They are designed to pressurize the plenum in which they operate and tek plenum fans are suited for supply or return air applications.
This design saves space by eliminating traditional scroll housings transitions and diffusers normally found within a plenum.
Plug fans offer great versatility for complex system configurations.
The fan wheel pressurizes the surrounding plenum allowing air to discharge in multiple directions.
A plenum fan consists of a centrifugal fan wheel without the surrounding housing.
Backward inclined airfoil wheels provide high efficiency performance and sound characteristics needed for the most stringent hvac applications.
With no fan shaft bearings or belts to maintain model apd eliminates the cost and maintenance associated with traditional belt drive plenum fans.
