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 MSAV
®
(Multi-Stage Air Volume) option are limited to a motor service factor of 1.0.
