I had an EGO blower mysteriously quit on me four days ago and I took it apart. I think I have a fan design that would be more efficient. When you look at the design of the jet fan in EGO blowers, you'll notice that the angle of the blades as they extend out decreases and is steepest at the bases of the blades. Also, the breadth ("broadness") of the blades decreases as you go farther away from the bases of the blades, the blades taper out in a way. If you multiply the broadness by some coefficient, maybe 1.5 or 2, will that make the fan blade move more air while spinning slightly more slowly? I know that I want to test this by designing it and using the Dremel idea maker and then creating a clay mold for the finished piece so I can cast it in ABS plastic (if possible), if not, aluminum... something light but durable.
I also would like to see if you go for a 15 to 30Ah backpack battery a blower that uses more input power and perhaps a fan that has blades that are broader but angled and curved the same way and that taper by the same factor. This blower would blow 1000+ CFM at some speed... maybe 125mph... It would use a much higher input power. Something for the professional, something that could replace a backpack blower.
