Foundations & Supporting Structures
(refer to lifting/safety section)
The AMX Mixed Flow Fans can be mounted horizontally, vertically or at any angle if ordered accordingly. Mounting brackets are
available to accept both floor mounted and hanging vibration isolation. Typical mounting arrangements are shown below.
When mounting to concrete, anchor bolts should be “L” or “T” shaped with sufficient length for nuts, washers, shims and threads
for draw-down. Each bolt should be placed in a sleeve or pipe with diameter larger than the bolt to allow for adjustment. When the
mounting surface and the surface of the fan base do not match, shim level. Do not distort the fan when tightening the anchor bolts.
A fan mounted to or within a structure should be placed as close as possible to a rigid member such as a wall or a column. The
structure must be designed for rotating equipment. Static design for strength is not sufficient to ensure operation at low vibration
levels. Supports for suspended fans must be cross-braced to prevent side-sway. Structural resonance should be at least 20% from fan
operating speed. Vibration isolators may help block the transmission of vibration into a structure. Any ducting should have independent
support; do not use the fan to support ducting. Flexible connections are required whenever the fan is supported on vibration isolators.
WARNING
