six inch vs four inch DC hose

I've been reading Bill Prentz's web site about DC.

He is very emphatic that 1000 cfm is necessary to collect the fine dust which can be a health hazard. And to achieve 1000 cfm, a 4 inch hose will not work. My primary concern is a table saw. Has anyone outfitted a table saw with a six inch outlet? How did it work out? thanks

I also have a 6" connection to the bottom of my Unisaw. That's hooked to a Oneida SDG, and the cabinet stays very clean. There is a 4" take off to the overblade guard as well, until I added that I still had a lot of sawdust kicking out of it.

First off Welcome to the forum.

Your question lacks important facts to get good answers. Type/size of DC system? 6" connections on a 1.5 hp DC would be useless.

How long of a run and what type of duct work? Smooth pipe and short runs or better.

What Hp system do you have? If your running a 6" and 4" Duct at a time the main duct would have to be 7" or larger. If not your losing efficiency.

To rrbrown, thanks for your comment. At this time I do not have the hardware. I have been looking at table saws and have decided on a Ridgid R 4512 due to the limited size and quantity of the projects I intend to make. Haven't decided on a dust collector yet. Been looking at a 1.5 hp Jet or Delta with a Wynn nano filter cartridge. Discharge to outside is not feasible for me. The Jet has a Six inch port. Don't know about the Delta. Am also wondering if anyone has hooked up two four inch hoses to a single table saw, in order to increase the cfm.
