Minimum CFM at 4" Dust Port: 400 CFM
Minimum CFM at 2

⁄2" Dust Port: 150 CFM
Do not confuse this CFM recommendation with
the rating of the dust collector. To determine
the CFM at the dust port, you must consider
these variables: (1) CFM rating of the dust col-
lector, (2) hose type and length between the
dust collector and the machine, (3) number
of branches or wyes, and (4) amount of other
open lines throughout the system. Explaining
how to calculate these variables is beyond the
scope of this manual. Consult an expert or pur-
chase a good dust collection "how-to" book.
