This whole adventure started with the purchase of a used 6” x 89” edge sander. Using a 2 HP, two bagger dust collector with an 11” impeller and running 20’ of 4” hose, I was able to collect about 50% of the dust through the 3 1/2” port, sigh…
Truth be told, I was looking for an inspiration/excuse to upgrade my system !
The addition of a top canister six years ago did eliminate “the puff of dust” at start up but cost me a small amount of CFM and the filter required regular cleaning. AND, I absolutely hated the bottom clamp/bag arrangement when reinstalling the bag after dumping :)
Much shopping later I decided I didn’t want to spend + $4000. The US to Cdn dollar exchange is at ~ 30% right now plus shipping to Canada is a killer. The ClearVue was the top contender but I decided for a one man shop, using one tool at a time, I didn’t really Need that much more CFM.
Instead, I chose to use my existing motor/impeller, add a Oneida Super Dust Deputy, a 35-gallon bin, a Wynn filter and a remote control.
Thanks mostly to Bill Pentz’s site and his static pressure calculator I was able to better understand static pressure losses and design my piping runs.
The collector part of the build was fairly straight forward but one doesn’t quite realize how many tools one has Until you have to convert all their dust ports from 4” to 5” :)
My anemometer arrived after construction was complete but I guesstimate I was generating about 350 CFM with the old system. Collection was adequate with decent dust ports on each machine, fine dust collection at the other end was not. Probably three times a year I would turn on my spray booth fan and use my air hose to “clean up” the shop.
The new system is averaging 460 – 516 CFM with a velocity of 3380 – 3900 ft/min.
There are now no hoses to trip on, dust bin emptying is a breeze, CFM has improved, the clean out box on the Wynn filter has less dust in it than there is on my coffee table….
Cost was roughly $2200 Cdn, I am one happy camper !
Over view, the clearance to the bottom of the 5” main spiral pipe is 6’ 4”.

And the edge sander that started it all. I made an angled work table (it didn’t have one) to take advantage of the full width of the belt and the new collection port has been moved forward so the center of the 5” port is at the front of the belt.
