For Standard Motor & Low Static Drive Accessory Fan Speed (RPM), reference
For Oversized Evaporator Fan Speed (RPM), reference
Fan motor heat (MBH) = 3.15 x Fan BHP.
Notes:
Data includes pressure drop due to standard filters and wet coils. No accessories or options are included in pressure drop data.
Refer to Table 54 to determine additional static pressure drop due to other options/accessories.
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 4000 and 5200 CFM, unit applications below 320 CFM/Ton are only applicable to TCD models only (No Gas Heat). See below for restrictions.
• Electric heaters restricted on applications below 320 CFM/Ton.
• Dehumidification (Hot Gas Reheat) or TXV with Frostat and Crankcase Heaters are required on applications below 320 CFM/Ton.

Field Supplied Fan Sheave B5V200 and Field Supplied Motor Sheave 1VP34 Required. Field Supplied Belt may be necessary.
(ii)
Field Supplied Fan Sheave BK190 Required. Field Supplied Belt may be necessary.
(iii)
