Axial fans use a propeller to create a flow of air the direction of the axis of rotation. Because they create a large airflow, axial fans are optimal for a wide variety of cooling and other airflow needs.
- High efficiency
- Low noise
- Alarm type
- Fan kit features axial flow fan, finger guard and mounting screws in a single package.
