Model Codes: 3 = three phase, A= aluminum blade, B= Blue Ribbon,H=high output, DB=36"belt drive, DB4=3/4"hp 36" belt, V=variable speed,C= corrosion resistant Notes:AFR is the airflow ratio. Highter AFR indicates better performance under static pressure or against wind. It is calaculated by dividing fan cfm at 0.20 static pressure by cfm at 0.05sp.
Sound leve measured 5ft in front of fan discharge. Amps measured at highest voltage. Amps at lower voltage approximately doubled. *Request 200 volt motor for 208 volt 3 phase applications. **Fan was tested at 230 volts with 4.20 amps, at 460 volts it will be 2.10 amps.
