All of Air Drive's fan blade designs are available
with hubs for mounting blades to motor shafts.
Air Drive's patented hub/locking
system delivers 75% more torque than conventional rolled-over
or peened hub attachments. You see a dramatic improvement in
mechanical power transmission from the drive motor shaft to the
fan blade assembly.
Hubs are supplied in either aluminum
or nickel plated steel material with steel, cup point socket
set screws for securing to motor shaft.
