Data
High Efficiency
✲Indicates both downflow and horizontal units.
Trane’s 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.
For Standard Evaporator Fan Speed (RPM), reference Table 53-1.
For Standard Motor & High Static Drive Accessory/Fan Speed (RPM), reference Table 53-2.
For Oversize Evaporator Fan Speed (RPM), reference Table 53-3.
