section 4: designing the
system
general
this dust collector can be operated as either a
stationary, central dust collector or a mobile unit.
there are advantages and disadvantages to both
setups. the advantage of the mobile system is
eliminating the cost of many ducts and fittings.
on the other hand, the stationary system is more
efficient and customizable.
if using this dust collector as a stationary system,
put the dust collector in an out-of-the way location
such as a corner or separate room. the dust col-
lector is capable of collecting dust from up to two
machines running simultaneously. grizzly offers
a complete line of dust collection accessories for
setting up a stationary, central dust collector sys-
tem. Additionally, grizzly offers a complete guide
book entitled Dust Collection Basics.
Whatever system you choose, always make sure
there are no open flames or pilot lights in the
same room as the dust collector. there is a risk of
explosion if dust is dispersed into the air.
always guard against
static electrical build up
by grounding all dust col-
lection lines.
duct material
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 generates static
electrical buildup that can
cause fire or shock. Properly
ground it to reduce this risk.

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.
