Our team is looking for a vacuum impeller to use on our robot. We want to get an effect similar to a shop vac, but do not want to purchase an entire shop vac just to get the impeller. The shop vac one is appealing since it is thin, metal, fairly small, and enclosed on both sides except for the vacuum hole. However, any reasonably powerful impeller will do. Any thoughts as to where to purchase one?
