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.
Refer to the figure below for a close estimation of
the airflow each machine requires. Keep in mind
that machines that generate the most sawdust
should be placed closest to the dust collector.
If the machine has multiple dust ports, the total
CFM required is the sum of all ports.

If the machine does not have a built-in dust port,
use the following table to determine which size of
dust port to install.
