NOTE - Using total air volume and system static pressure requirements determine from blower performance tables rpm and motor output required. Maximum usable
output of motors furnished are shown. In Canada, nominal motor output is also maximum usable motor output. If motors of comparable output are used, be sure to keep
within the service factor limitations outlined on the motor nameplate.
NOTE – Units equipped with Multi-Stage Air Volume option are limited to a motor service factor of 1.0.
