Better impeller for better DC performance

[phil_o]

I came across an article online at the American Woodworker website titled "Soup up Your Shop" about half way down on this page http://www.americanwoodworker.com/blogs/reviews/archive/2013/11/12/soup-up-your-shop.aspx they suggest replacing the dust collector impeller with a better one.:

4. Better Impeller. Has your shop outgrown your 2-hp collector? Before you buy a 3-hp collector, consider upgrading the impeller on your old machine. An aftermarket impeller from Oneida Air Systems will fit most 2-hp collectors and improves cfm by 30 to 80 percent. In testing,we found the more you load your collector, the greater the benefit. The large fins offer greater surface area to move more air. Plus, these impellers are statically and dynamically balanced so they run truer and help extend the life of your motor.

Also I found a web site that sells air foils (implellers) http://www.continentalfan.com/ecatalog.php?fantype=industrial&fid=18&s=OEM+%26+Replacement+Impellers

I'm wondering if anyone has tried an impeller upgrade or has an informed opinion on the subject.

I have one of Oneida's 2hp DC's. It has one heck of a suction. I have to watch out for tools and gloves near the collection hose or I'll be digging in the dust bin later.

google Bill Penz dust collection
he has the most complete research on dust collection I have ever seen.
several paragraphs about using the airfoil impellers, there are a few dos and don't s
funny, just yesterday I was looking at continental impellers I have and thinking to use one with my cyclone.
they are supposed to be much quieter than standard "straight" vane metal
