Has anyone done a top hat with a six inch to the blower and four inch to the equipment? I would like six inch everywhere but may have to use a tapered reducer at the seperator for a while
I am making a separator with a 5? outlet to D.C. And 4? to tools. Not a central system. I will hook up to tools individually. Is it ideal? No. But it is all I can justify money wise. I ordered the 5" tube yesterday. $6 for part, $11 to ship. I wish home centers sold 5".
Around here (Bend, Oregon) Home Depot sells 5" duct
But it's 30 gauge. To get 26 gauge, you have to order it from the HVAC guys.
