Centraxial Blowers
 |
Rotron Centraxial Blowers have an impeller that, unlike the Centrifugal Blower, achieves a substantial portion of conversion of velocity energy to pressure energy within the impeller itself. This impeller is much less dependent upon a scroll or housing and may therefore be operated without a scroll or housing with a relatively small loss of in performance and efficiency. The impeller function is similar to a turbine impeller.
