Data
Factory supplied motors, in commercial equipment, are definite
purpose motors, specifically designed and tested to operate
reliably and continuously at all cataloged conditions. Using the
full horsepower range of our fan motors as shown in our
tabular data will not result in nuisance tripping or premature
motor failure. Our product’s warranty will not be affected.
5 HP Oversize Motor & Field Supplied Drive
For Standard Evaporator Fan Speed (RPM), reference Table PD-31.
For Oversized Evaporator Fan Speed (RPM), reference Table PD-33.
Fan motor heat (MBH) = 3.15 x Fan BHP
Data includes pressure drop due to wet coils and filters.
No accessories or options are included in pressure drop data.
Refer to Table PD-35 to determine add’l static pressure drop due to other options/accessories.
Notes:
1. Field Supplied Fan Sheave BK90 Required. Field Supplied Belt may be necessary.
2. 5 HP Oversized Motor with Field Supplied Motor Sheave IVL40 Required. Field Supplied Belt
may be necessary.
3. For 380V/60 Hz units, the oversized motor is used as the standard motor. Refer to “Motor &
Sheave/Fan Speed” tables to determine operating range.
