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.

NOTES:

Blower performance is based on cooling only unit, with fixed outdoor air, 2" T/A filters and a dry evaporator coil.
Refer to page 14 for additional static resistances.
ESP - External Static Pressure available for the supply and return air duct system. All internal unit resistances have been deducted from the total static pressure of the
blower.
