External-Motor Rectangular Duct Centrifugal Fan
External-Motor Rectangular Duct Centrifugal Fan
The external-motor rectangular duct centrifugal fan keeps the motor outside the airflow, so it is used to extract high-temperature, humid or greasy air. It is widely preferred in the rectangular ventilation ducts of hotels, malls, hospitals and factories, in tight installation spaces.
