Centrifugal Backward Fan Box (CPB)

The Bostanchi Industrial Group Silent fans are suitable for sound sensitive areas. These Quiet in-line Centrifugal fans combine the high-pressure benefits of a centrifugal fan with the reduced sound levels using sound reducing insulation to provide quiet air movement.
Because they are powerful, these fans ensure that the system will move air even when the system resistance is much higher than expected. Therefore, the Silent box range is able to quietly cope with a pressure drop of the flexible duct as well as spiral ducting For CPB model, the plug backward impeller with galvanized housing is utilized. Motors are available in three phases with 4 or 6 poles, depending on the model. The impeller is connected directly to the motor.
