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 filter,
so you don't end up with a system that only
works right when the filter is clean.
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 maximum static pressure loss
found on the data sheet for your machine
(located toward the front of this manual).
—if the CFm for your static pressure loss
is above the requirement of the machine,
then the line will most likely be success-
ful. Congratulations! you’ve just designed
your own dust system. Compile a list of
materials and refer to
accessories 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.
compile materials list
After the system is designed, create a materials
list of all the items you will need to build your dust
collection sytem. this will make it easy when it
comes time to purchase the materials.
Below is an example of some items that might be
needed. refer to
accessories for dust collection
components available through grizzly.com.
3. Add the additional factors from the following-
table to your list.
