Single Inlet Forward Centrifugal fans and 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.
Forward centrifugal blowers always require scroll housing, which is open on one side. The characteristic features of this product series are high efficiency, a low noise level, relatively small air flow with a high increase in static pressure, robust design and space-saving application.
