Spiral pipe and Wye source in IL

[lloydfurn]

Air Duct Mfg in Lombard IL has great prices on spiral duct, wyes, transitions, and bellmouth fittings (to attach pipe to machine)

For example:
6" spiral pipe, 10' length 26 GA: $16.40 each
6x6x4 lateral 45 degree wye: $23.25
6" 90 degree elbow (1.5R): $10.37
6x5 reducer: $9.35
6" bellmouth: $9.44
They quoted a 7.25" x 5.75" to 9" transition at $68.

All the elbows and reducers under 12" diameter are 2 piece die stamped and welded; very smooth with no gores.

I've no connection to them.
I'm rebuilding my system due to a shop move and can no longer vent outside. So I'm probably changing over from my old Oneida cyclone to a clearvue with filters and have found this discussion group very helpful, thanks for all the info.

BTW, anybody want to buy a 1250 CFM cyclone and blower?
