I have a 2 hp Jet dust collector...my first...there are two 4" intakes
on the unit....is it best to run 4" hose around the small shop rather
than 3"...etc...and when dropping to a tool...should you keep using
mostly 4"...or is it ok to drop down to 3" or 2 1/2" at the split off
fitting to the stationary tool ?

Thanks, TR


It is best to keep the hose as large as possible up until you have to taper
down for a particular tool. I use 20' of 4" flex hose up to every tool and
use an adapter if necessary at that point to go smaller, or in the case of
my planer, larger.
