DC blower fans are the ones that feature a circular impeller, which is enclosed in a cage. This design allows blower fans to create a concentrated airflow in high-pressure conditions. The fans pull air from the sides and release it at a 90° angle. DC blower fans are centrifugal blowers that utilize impellers to increase the volume of airflow. These blowers assure radial air displacement, where the direction of airflow changes during the input to output phases. Sofasco International provides industrial DC blower fans in a wide range of performance characteristics, functionalities, and materials.
