It’s occured to me recently that my furnace produces a lot of air movement, very likely much more than my 2HP dust collector. It feeds more than 10 ducts around the house.
At the same time – it is so much more quiet you can’t even compare the two. It’s never even occured to me to wear ear protection next to my running furnace.
What if I looked for a used house (or RV) furnace, ripped out the heat exchanger, added a cyclone and dust bag, and made my own dust collector? Would that perform comparably to one of the 3000$ dust collectors I could buy?
Has anyone tried?
