We got a steal of a 5 hp Delta cyclone from a school shop auction. Big upgrade over our 2 hp grizzly we use 4” flex hose with. At the school I was able to get all of the 8” dust collection piping. It is very heavy gauge metal. It is enough to duct our entire shop but I do not have any Wye fittings. I am not sure what to use. I have looked at the ventilation Wyes at Home Depot that are 8”x8”x8”. They feel a little light weight but still feel stiff enough. So I wonder if a 5 hp cyclone will suck those Wyes flat or not.

Not sure if it matters, but I plan to leave our DC in a shed area and it will not have any filter since no person will be in the shed with the DC when it runs. I am not sure, but I think the DC is rated at 2000 cfm, I could be wrong though as I cannot remember.

I don’t think a 5 hp will suck a small piece of 8×8 flat. 25 hp will suck a 48×48 in, but not quite flat ;-))

According to Bill Pentz’s web site, the lighter gauge piping will suck flat, but the lighter weight fittings are fine. All the bends on the fittings give them extra support. Home Depot’s website says they carry some fittings in heavier gauge, but not all; I was looking for 6” so I can’t say for sure about 8”. If you do a search, and they have them, you can order online with no shipping charge, so it’s not a bad option.
