Note: Systems with powerful dust collectors work
better if multiple blast gates are left open. This
also allows you to run two machines at once.
Experiment with different combinations of blast
gates open/closed to find the best results for your
system.

Here are some frequently asked questions
when determining branch line sizes:
How do I figure which size of branch line to
use if the machine has two dust ports?
