Therefore, Cougar has designed unique fan impellers that ensure a balanced correlation between such parameters as static pressure, noise level and airflow. The implementation of aerodynamic elements on the internal part of the frame in combination with the grooves on the impellers are able to promote for an improved airflow focusing; this is achieved due to the acceleration of airflow in edge area.
All Vortex fans are based on a hydrodynamic bearing that provides for the prolonged lifetime and …
