I use 28 gauge metal A/C pipe from Home Depot and seal it with metal A/C tape. It has worked great for my dust collection system, which pulls 2200 cfm. I started with an eight inch duct size and then dropped it to six inch on the big tools and then on down to four inch at the ceilng on tools that have only a four inch ports. I use only LEE YALLEY self cleaning blast gates. I had some other guys say that it would not work and that was why they had spent over 5X times as much money for the “good” pipe than I did for mine. I told them “It is only air pipe, I am not walking on it”. They don’t like the fact that I have be running my “cheep” system for over nine years with zero problems. I also do not have any sparking problem, that you can get with PVC pipe.
