As I read and think about moving dust around I found this interesting contraption. I know that gentle bends have less of a CFM penalty than right angles. But as anyone pricing 6" wyes knows this gets costly fast. I have explored what it would take to make my own wyes and Pentz refers to a number of DIY solutions.
But what do others think of this junction box blast gate unit?
There is the introduction of more volume in the pipe line, but does it address the dynamics that make T-joints and right angles so problematic. I don't know what to think of it. [IMG]file:///Users/bseidner/Library/Caches/TemporaryItems/moz-screenshot-1.png[/IMG]
