I’m pretty sure I’m not the first to think dust collection ducting and fittings are laughably expensive. I’ve priced PVC and 4” metal ducting and they seem like they would work just as well. I’m a little less sure what to do about the 5” to 6” conversion.

My entire shop is hooked up with this: I also get my reducers and elbors when needed here.

In fact I just ordered 50’ yesterday because we have to do another run to add our CNC to the set up. I use the 26g and never have had any issues. It goes together quick and easy and has always worked great for us.

I get my Wye branches from “thesheetmetalkid”, he is easy to find online and does ebay listings also.

I get my 6” flex from Pennstate dust collection. All in all I don’t find it that expensive. Shipping will hurt some but if you get all of your pipe you need at once you will save in the long run on the shipping cost.

I installed a 6” sheet metal duct system made of 6” 26 gauge snap lock duct and 6” 26 gauge fittings. I was able to find the 26 gauge 6” snap duct, 90° elbows and reducers at Ferguson. There price was about half that of Home Depot. I found the flue style wyes at Home Depot online. Regular HVAC wyes have the crimp on the wrong end. HVAC wyes are made for pressure system not vacuum systems. I used 2 of the 26 gauge HVAC wyes at each 90 degree location set at 45 degrees, this gives you a 2.5 run to angle ratio.

For 6” Blast gates I made my own. I put up about 150’ of duct, 20 wyes, 13 – 6” blast gates, 7- 4” gates, 25 – 90 degree ellbows for around $700.00 including all of the flex duct used for final connections to equipment.
