INERTIA BASE

(isolation base with rebar - filled with concrete by customer)

Inertia bases provide a common support to fan, motor and
drive including guards and utilize heavy duty structural channel
with spring isolators. Inertia bases incorporate reinforcing rods
(rebar) and require customer supplied concrete. Inertia bases are
typically used on longer, direct drive fans to mitigate assembly
deflection, maintaining proper alignment between the motor,
coupling, shaft and bearings. Flexible connectors at inlet and
outlet are required. Shown with optional bottom pan to allow
for easier filling of concrete in the field.
