TIPS FOR OPTIMUM PERFORMANCE
• Avoid using more than 10” of flexible hose on any ducting line. The ridges inside flexible hose
greatly increase static pressure loss, which reduces suction performance.
• Keep distance between the dust collectorr and machines as short as possible.
• Keep ducting directional changes to a minimum. The more curved fittings you use, the
greater the loss of suction at the dust-producing machine.
• Gradual directional changes are more efficient than sudden directional changes
(i.e. use 45° elbows in place of 90° elbows whenever possible).
• The simpler the system, the more efficient and less costly it will be.

CFM BY MACHINE TYPE
All woodworking machines require effective Dust extraction to ensure quality work and longevity of
the machine itself. Most machines will have a minimum rated CFM extraction requirement available.
Please note that CFM requirement is usually measured at the point where the dust hose is
connected to the machine’s dust port, which is very different to the rated CFM of the dust collector.
The length and complexity of your entire dust extraction and collection network should be taken
into account.
Bandsaws & Table Saws
Lower volume waste producing machines (with smaller particles) such as bandsaws & table saws
require a minimum airflow rating between 400 and 500 CFM to work efficiently
Thicknessers, Jointers & Router Tables
High volume waste producing machines (such as thicknessers, jointers & router tables) require a
minimum airflow rating at the machine, between 750 and 950 CFM
Wide Drum & Belt Sanders
Wide Drum & Belt Sanders, despite their lack of heavy waste production, require significant CFM
rating to remove the dust and keep the sandpaper from clogging prematurely, both types requiring
in excess of 950 CFM at the machine to work efficiently and not affect the machine’s warranty.
