Oneida is the Gorilla (no pun intended) in the advanced shop market. I chose a tempest from Penn State Industries.Very happy with my choice, customer service, assistance and quality of products all very good. And yes I would do it again.
I keep looking at the adds and drooling over a bigger impeller, higher horsepower, but in reality I have never been underpowered in my modest shop.
14 inch impeller, 230v system
Use them (the manufacterer) as a resource in laying out the duct work and pay heed to the advice on 45 degree vs. 90 degree drops and size and quality of ducts. You will spend a ton on the quality ductwork but it will make or break the system.
Make sure you get a air filtration system with timer for the fine dust that will settle after you close up the shop for the night.
And pay zero attention to the post that will come in about #7 about their shop vac being just as good. It really isn't.
