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.
Figure 5:
Horizontal Hanging or Base Mount
With a hanging mount, the motor may be located on
either top or bottom. The base mount allows top motor
location only. Both options provide access panels on
two sides.
