G0508 10 HP Industrial Dust Collector
-17-
Duct Material
General
The Model G0508 can be operated as either a sta-
tionary or mobile unit. There are advantages and
disadvantages to both set-ups. The advantage of
the mobile system is eliminating the cost of many
ducts and fittings. On the other hand, the station
-
ary system is more versatile and convenient.
The Model G0508 is designed to be a central
dust collector system. Locate the dust collector
in an out of the way location such as a corner or
separate room. The dust collector is capable of
collecting dust from up to eight machines running
simultaneously. The large suction capacity of the
Model G0508 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.
A 5-port inlet is included with the Model G0508
for quick and economical dust collection setup.
However, depending upon your system design
using this feature, bags may fill at different rates
requiring you to empty some bags more often
than others.
Whatever system you choose, always make sure
there are no open flames (including pilot lights) in
the same room as the dust collector; otherwise
you risk an explosion if dust is dispersed into the
air.
SECTION 4: DESIGNING THE
SYSTEM
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 a 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.
Metal Duct
Advantages of metal duct is its conductivity and
that it does not contribute to static electrical
charge build-up. However, static charges are still
produced when dust particles strike other dust
particles as they move through the duct. Since
metal duct is a conductor, it can be grounded quite
easily to dissipate any static electrical charges.
