Dust collector duct drop sizing
Finally getting around to installing my 3hp Jet dust collector. Collector will be located in a separate room, adjacent to shop. Several questions:
Should the separator be located just before the collector or closer to the machines?
Multiple small separators at machines or just 1 at collector?
Using 6" pvc for main run about 45' max. For 4" hose, connection should 6" be used all the way to machine port with a 2-3' of 4" flex hose or come off main with 4" pvc to machine port with 2-3' of 4" flex hose. Difference is about 6-8 feet of 6" versus 4" pvc pipe. Easier and less costly to use the 4" but don't know if worth any efficiency loss.
Can't picture more than 1 machine running at a time, but since I am old I'm sure I will forget to close a blast gate or 2 or 3.....:)
Loss of 6" 90 deg elbow appears to be the same as 2 45's, why do most recommend using the 45's?
Thanks for any help
