4. Total your list as shown in the example
below to come up with your overall static
pressure loss number for that line.
Note: Always account for a seasoned fi lter,
so you don't end up with a system that only
works right when the fi lter is clean.
Main Line
6" Rigid Duct (0.037) at 20' ................ 0.740
Branch Line
4" Rigid Duct (0.075) at 10' ................ 0.750
4" Flexible Duct (0.28) at 5' ................ 1.400
Elbows/Branches
6" 45˚ Y-Branch ................................ 0.329
4" 45˚ Elbow ........................................ 0.225
Additional Factors
Seasoned Filter ................................ 1.000
Total Static Pressure Loss ........................ 4.444
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 on the per-
formance curve for your dust collector.
Example: A typical Data Sheet Performance
Curve is illustrated in the figure below. Find
the total static pressure loss on the Static
Pressure axis (4.4 in the current example),
then refer to the closest value on the CFM
axis—approximately 1120 CFM.
The 1120 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 your static pressure loss
is above the requirement of the machine
connected to the end of that branch line,
then dust collection will most likely be
successful. Congratulations! You've just
designed your own dust system. Refer to
the Accessories section of this manual to
start buying the components necessary to
make your system a reality.
— If the CFM for your 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.
