Below are some terms that will help you to understand
and setup your Dust Collector and design your own
Dust Collection System.
Dust Collector - A machine used to collect fine wood
dust and chips.
Dust Collection System - A dust collector connected
to multiple woodworking machines utilizing various
types of hose/pipe and fittings.
C.F.M. = Cubic Feet/Minute - A measurement of the
amount of air volume that can move through a dust
collector in one minute.
Static Pressure - A measurement of the amount of the
resistance to airflow in a dust collection system.
THINGS TO CONSIDER:
,, What is the maximum C.F.M. required for each tool
you intend to use? Your Dust Collector should be
rated for the tool that has the highest C.F.M.
requirement.
,, Will two or more tools be running at the same time?
The Dust Collector should be rated to handle the
combined C.F.M. requirements of all operating tools.

HELPFUL HINTS:
,, Always run the largest appropriate diameter hose
as far as possible. Running a smaller diameter hose
will greatly reduce the C.F.M. at the tool, yielding
marginal dust collection.
• The use of a low rated micron filter and collection
bag can increase the effectiveness of your dust
collector in removing fine particles of dust.
,, Determine if you are to use your Dust Collector in a
Dust Collection System or as a direct hook-up to an
individual tool. If used in a Dust Collection System,
review Static Pressure Requirements on page 16.
To protect yourself from a static shock, ground the dust
collection system to a known ground.
If using the Dust Collector in a Dust Collector System,
make certain to:
Ground the dust collection system to a known ground.
,, Always keep blast gates closed to unused tools.
• Make all runs as short as possible, minimizing the
number of bends or turns that could greatly reduce
the efficiency of your Dust Collector.
,, Position the tools that have the highest C.F.M.
ratings closest to the Dust Collector.
