G1028Z/G1029 Dust Collector -15-
Material Selection
General
You have many choices regarding main line and
branch line duct material. In most commercial
workshops, the main line and branch lines are
usually metal duct. Flexible hose is then used to
connect each machine to the branch lines. In the
case of small home shops, flexible hose may be
used for both main line and branch line ducts.
Plastic duct is also a popular material for home
shops. Please 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 the manual.
METAL DUCT
Metal duct comes in many varieties. Stove pipe,
heating/ventilation duct and duct made especially
for dust collection are all options. 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 con-
ductor, it can be grounded quite easily to dissi-
pate any static electrical charges. However, metal
duct is generally more expensive than plastic duct
and it is not usually airtight unless specifically
manufactured for dust collection. Specially manu-
factured metal duct, on the other hand, is quite
expensive. Metal duct is also generally more diffi-
cult to cut and assemble.
FLEXIBLE HOSE
Flexible rubber hose, polyethylene, plastic flex-
hose and other flexible ribbed hose is generally
used for short runs, small shops and at rigid duct-
to-tool connections. There are many different
types of flex hose on the market today. These are
manufactured from materials such as polyethyl-
ene, PVC, cloth hose dipped in rubber and even
metal, including steel and aluminum.
The Model G1028Z/G1029 can be operated as
either a stationary or a mobile unit. There are
advantages and disadvantages to both set-ups.
The advantage of the mobile system is eliminat-
ing the cost of many ducts and fittings. On the
other hand, the stationary system is more versa-
tile and convenient.
The Model G1028Z/G1029 is designed to be a
central dust collector system. Locate the dust col-
lector in an out of the way location such as a cor-
ner or separate room. The dust collector is capa-
ble of collecting dust from up to two machines
running simultaneously. Because of the large
suction capacity of the Model G1028Z/G1029,
great flexibility is possible in the 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
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 dispursed into the air.
