Dust Collection
Since each machine produces a different amount of sawdust, the requirements for the minimum amount of CFM to move that sawdust is unique to the machine (for example, a planer produces more sawdust than a table saw). Knowing this required CFM is important to gauging which size of duct to use.
Based on the dust port size of the machine to be connected to the dust collector, Figure 10 will give you a close estimation of the CFM that is reduced because of dust port size. A machine that generates large wood chips should be placed as close to the dust collector as possible.

If your machine doesn't have a built in dust port, use Figure 11 to verify which size of ducting to install on your machine.
