The S.N.C. is the result of three different research lines. Firstly, we get higher performance due to the sickle blades, secondly, due to the winglet applied at the end of the blade we debug turbulences and thirdly, in order to reduce the sound level we designed a serrated profile at the rear of the blades. The S.N.C. blade compared with the traditional ones gets better performance in airflow and pressure; decreasing the power needs and sound...

Open the catalog to page 10Advantages winder impellers versus traditional ones Better performances with less sound level On this graph, we can be observed the advantages of the winder impellers versus the traditional ones. The sickle form from the blade (A) will enable better performances. If we add to the sickle blade the winglet (B) we will get a high reduction in turbulences. And finally, adding the serrated profile (C) we still increasing the performance and we reduce significantly the sound level. The combination of the winglet, the serrated profile and the sickle form gets a better performance in airflow and...
