NOTE - Using total air volume and system static pressure requirements determine from blower performance tables rpm and motor hp required.
Maximum usable hp of motors furnished are shown. In Canada, nominal motor hp is also maximum usable motor hp. If motors of comparable hp
are used, be sure to keep within the service factor limitations outlined on the motor nameplate.
