always guard against stat-
ic electrical build up by
grounding all dust collec-
tion lines.
the Model g0637/g0638 is designed to be a cen-
tral dust collector system. install the dust collector
in an out of the way location such as a corner
or separate room. the large suction capacity of
the Model g0637/g0638 allows great flexibility
in planning and designing of your dust collection
duct layout. grizzly offers a complete line of dust
collection accessories for setting up a stationary
system. Additionally, grizzly offers a complete
guide book titled Dust Collection Basics.
Whatever system design you choose, always
make sure there are no open flames (including
pilot lights) in the same room as the dust col-
lector; otherwise you risk an explosion if dust is
dispersed into the air.

You have many choices regarding main line and
branch line duct material. For best results, use
metal duct for the main line and branch lines, then
use short lengths of flexible hose to connect each
machine to the branch lines.
Plastic duct is also a popular material for home
shops. However, be aware that there is a fire or
explosion hazard if plastic duct material is used
for dust collection without being grounded against
static electrical charge build-up. This topic will be
discussed later in this section. Another problem
with using plastic is that it is less efficient per foot
than metal.
plastic duct
the popularity of plastic duct is due to the fact
that it is an economical and readily available
product. it is also simple to assemble and easily
sealed against air loss. the primary disadvantage
of plastic duct for dust collection is the inherent
danger of static electrical build-up.

Plastic duct generates static
electrical buildup that can
cause fire or shock. Properly
ground it to reduce this risk.
