ZJTEX Forward Curved Centrifugal Blowers use the same versatile external rotor motor as our motorized impellers. The forward curved motorized impellers are designed to provide optimal performance when operated with a scroll housing designed by ZJTEX. Single Inlet Forward Curved Centrifugal Blowers are compact units that can be used to either pressurize or evacuate in air moving applications. The impellers are permanently mounted to the external rotors for ease of installation and maintenance-free operation. These units may be mounted in any orientation to provide maximum airflow in minimum areas.
