1. All motors have a nominal speed of 1800 RPM, a 1.15 service factor and a solid base. They can operate to the limit of their service factor because
they are located in the moving air, upstream of any heating device.
2. Do NOT close this pulley below 1 turn open.

1. Deduct these resistance values from the available external static pressures shown in the respective Blower Performance Table (See Note 2 for
exception.)
2. Since the resistance to air flow will be less for horizontal duct connections than for bottom duct connections, add these pressures to the ESP values
on the respective unit's blower performance table.
