For Standard Evaporator Fan Speed(rpm),reference Table 22, p.44. <br /> 2. Data includes pressure drop due to standard filters and wet coils. No accessories or options are included in pressure drop data. <br /> 3. Data does not include pressure drop due to reheat coil. <br /> 4. Refer to Table 29,p.46 to determine additional static pressure drop due to other options/accessories. <br /> 5. 1-hp Fan Motor Heat(MBh)= 2.7672 x Fan bhp+0.4705. <br /> 6. Factory supplied motors,in equipment,are definite purpose motors,specifically designed and tested to operate at all cataloged conditions. Using the <br /> 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 <br /> warranty will not be affected. <br /> (a)Field Supplied Fan Sheave AK71x3/4"required.
