well, i have a 15" planer which would require a bit more cfm than a
13" planer. my machine is purported to need 800 cfm to move the chips
from it. also, a stationary versus a portable setup changes things as
well... since (as we all know) you suffer a cfm drop with each foot of
duct (or pvc pipe, or whatever) and even more with each turn.
i use the 3 hp dusty that i mentioned to collect from 8 large
stationary machines in a 20x40 shop. your mileage may vary.
