too many sharp bends in ducting.
5. Lumber is wet and dust is not flowing
smoothly through ducting.
6. Ducting has one or more leaks, or too
many open ports.
7. Not enough open branch lines at one time,
causing a velocity drop in main line.

(Page 39).
3. Remove ducting from dust collector inlet and

re-secure ducts; remove sharp bends. Refer to
Designing the System in manual.
5. Process lumber with less than 20% moisture
content.
6. Seal/eliminate all ducting leaks; close dust ports
for lines not being used. Refer to Designing the
System in manual.
7. Open 1 or 2 more blast gates to different branch
lines to increase main line velocity.
8. Install correctly sized ducts and fittings (Page 22)
Refer to Designing the System in manual.
9. Use a dust collection hood on a stand (Page 34).
10. Install a larger dust collector.
