Centrifugal Inline Fans
5
®
Mounting brackets are turned 90° for vertical mounting.
Access panels are located on the two sides adjacent to
the motor.
All fan models can be mounted horizontally, vertically
or at an angle. For ease of installation, knockouts are
provided at each location where mounting brackets
are shown in Figures 5, 6 and 7. Optional brackets are
universally adjustable to mount in any of these locations.
With either a hanging or base mount the motor may
be located on either side. The base mount allows top
access panels only.

Flex duct is recommended for mounting to the inlet
of the fan to allow for fitting adjustments. If the inlet
venturi requires adjustment, it can be detached from
the unit via the fasteners located on the inlet panel.
