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 successful.
Congratulations! you've just designed your
own dust system. refer to
page 30 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.
since plastic hose is abundant, relatively inex-
pensive, easily assembled and air tight, it is a
very popular material for conveying dust from
woodworking machines to the dust collector. We
recommend using flexible hose (flex-hose) to
connect the woodworking machine to the dust
collector. however, plastic flex-hose and plastic
duct are an insulator, and dust particles moving
against the walls of the plastic duct create a static
electrical build up. this charge will build until it
discharges to a ground. if a grounding medium
is not available to prevent static electrical build
up, the electrical charge will arc to the nearest
grounded source. this electrical discharge may
cause an explosion and subsequent fire inside
the system.
to protect against static electrical build up inside
a non-conducting duct, a bare copper wire should
be placed inside the duct along its length and
grounded to the dust collector. you must also
confirm that the dust collector is continuously
grounded through the electrical circuit to the elec-
tric service panel.
if you connect the dust collector to more than one
machine by way of a non-conducting branching
duct system and blast gates, the system must still
be grounded as mentioned above. We recom-
mend inserting a continuous bare copper ground
wire inside the entire duct system and attaching
the wire to each grounded woodworking machine
and dust collector.
system grounding
always guard against
static electrical build up
by grounding all dust
collection lines.
