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.
1
1 hp blower motor is not available for 208/230V-1ph applications.
2
1.5 hp motor is required with ZA05, ZA06 and ZAA03 drive kits.
