Note: When calculating static pressure loss
to determine if multiple lines can be left open
at the same time, only include the main line
numbers once.

5. Compare the total static pressure loss for
that line to the closest CFM given in the
Performance Curve section on the Machine
Data Sheet for your dust collector on Page 6
(Model g0442) or
(Model g0442) or
Page 9 (Model g0601).

Find 4.4 on the static pressure axis (the
amount of total static pressure loss calcu-
lated in

value on the CFM axis—approximately 1785
CFM.

the 1785 CFM for the static pressure loss of
the line connected to the router is well above
the 220 CFM requirement of that machine.

— if the CFM for the static pressure loss is
above the requirement of the machine con-
nected to the end of that branch line, then
dust collection will most likely be success-
ful. Congratulations! you've just designed
your own dust system.

dust collection will most likely be success-
ful. Congratulations! you've just designed
your own dust system.
— if the CFM for the static pressure loss is
below the requirement of the machine, then
that line will not effectively collect the dust.
you must then modify some of the factors
in that line to reduce the static pressure
loss. some of the ways to do this include:
1) installing larger duct, 2) reducing amount
of flexible duct used, 3) increasing machine
dust port size, 4) moving machine closer to
dust collector to eliminate duct length, and
5) reducing 90˚ elbows or replacing them
with 45˚ elbows.
