Arrangement 9 (Axial)
The belt driven Arrangement 9 is the perfect choice for applications which require the motor to be
out of the airstream. Driven by either a fixed or adjustable V-belt drive system, the exact point of
rating can be easily achieved. Any future change in rating can be accomplished through a simple
sheave change or blade angle adjustment.

Arrangement 1 — Lab Exhaust Fans
Arrangement 1 is belt driven. The wheel is overhung on the shaft, i.e., mounted at the end of the
shaft. The two fan bearings are mounted on the bearing pedestal, out of the airstream, which makes
them ideal for high temperature or contaminated air applications. Belt driven configurations offer
performance flexibility. The motor can be mounted in any of the four AMCA standard motor
positions, W, X, Y, or Z.

Arrangement 4 — Lab Exhaust Fans
Arrangement 4 is a direct drive fan. The wheel is mounted directly to the motor shaft with the motor
mounted to a pedestal (BAIFE and BCIFE) or motor drive plate (TVIFE). Arrangement 4 offers low
maintenance since there are no fan bearings, fan shaft or drive parts to maintain.
