The Role Of Impellers on Snowblower Performance
Original Message   Sep 29, 2010 10:05 pm
I was reading about the Clarence impeller improvement online today. It attaches a rubber gasket to each impeller blade ceiling it against impeller housing. Most who tried it seemed to report outstanding results especially with heavy wet snow. The only place where some reported it may not be effective were on units, such as the Honda, that reportedly have very tight clearances tween the impeller blades and the housing from the factory.

Ariens snowblowers are well-known for their high-capacity high capacity. Well most large snowblowers at 12 inch diameter impellers, the Ariens have 14 inch. That is over 16% faster speed at the end of the impeller blade. Does that give them a decisive edge?

So the question is: how important is the design of the impeller to the overall system performance? Are tight clearances between the impeller and it's housing critical? If so, which brands have the tightest ones? Is the diameter of the impeller critical? If so, did he Ariens and others with large impellers have a distinct advantage? The Clarence kit is inexpensive if you can install it yourself. Should everybody be installing these kits? TheToro has a unique impeller housing. Partially plastic, it has a return for excess snow to be returned to scoop. The effective Toro and edge or is it a disadvantage?
