Model Number Code
The model number code system is designed to completely identify the fan. The correct code letters must be specified to designate belt or direct drive. The remainder of the model code is determined by the size and performance.
GB - 240 HP - 5 or A
Motor HP (Belt Drive only)
6 = 1/6 10 = 1 50 = 5 4 = 1/4 15 = 1½ 75 = 7½
Configuration
G - Direct Drive
GB - Belt Drive
Fan Size
060 through 540
Wheel Pressure Level
3 = 1/3 20 = 2 100 = 10 5 = 1/2 30 = 3 150 = 15 7 = 3/4
Motor RPM (Direct Drive only)
A = 1725 D = 1550 B = 1140 E = 1050 C = 860 G = 1300
International Only K = 950 RPM J = 1475 RPM
VG = Vari-Green
