Model T28798 (Mfd. Since 12/18)

-17-

There are a number of options when it comes to 
metal duct, but duct that is specially manufactured 
for metal dust collection is the best choice. When 
selecting  your  metal  duct,  choose  high-quality 
metal  duct  with  smooth-welded  internal  seams 
that will minimize airflow resistance. This type of 
duct  usually  connects  to  other  ducts  or  elbows 
with  a  simple,  self-sealing  clamp,  is  very  quick 
and easy to assemble, and can be readily disman-
tled and re-installed. This is especially important 
if you ever need to change things around in your 
shop or add more tools.

Overview

Always guard against stat-

ic electrical build up by 

grounding all collection 

lines.

This dust collector is designed exclusively to col-
lect dry metal, chips, and swarf. 

DO NOT use this 

dust collector to collect wood dust or metal chips 
containing  cutting  fluid  or  coolant.  Due  to  fire  or 
explosion risk, 

DO NOT use this machine to col-

lect combustible or explosive metals, magnesium, 
niobium,  tantalum,  titanium,  zirconium,  hafnium, 
combustible  liquids  or  fuels,  gasoline,  or  oil-  or 
solvent-based paints. 

For  best  performance,  place  this  dust  collector 
as close to dust-generating machines as possible 
and install blast gates at the beginning of ducting 
lines. Only open one line at a time to focus maxi-
mum suction at the machine where dust is being 
collected. 

Grizzly  offers  a  complete  line  of  dust  collection 
accessories  for  setting  up  your  dust  collection 
system ductwork (see 

Page 21) and a complete 

guide book titled Dust Collection Basics.

Whatever  system  design  you  choose,  always 
make sure to position ducting and collector away 
from  any  open  flames  (including  pilot  lights); 
otherwise you risk an explosion if material is dis-
persed into the air.

Duct Material

For  best  results,  use  only  smooth-wall,  sheet-
metal ducting or flexible metal ducting to connect 
each machine.

The  National  Fire  Protection  Agency  (NFPA) 
warns of explosion or fire hazard because of static 
electrical buildup if plastic or non-conductive duct 
material  is  used  for  metal  dust  collection  and  is 
not  completely  grounded  and  bonded.  We 

DO 

NOT recommend using any plastic duct material 
with this machine.

Metal Ducting

Figure 11. Examples of metal duct and 

components.

Advantages  of  metal  ducting  is  its  conductivity 
and that it does not contribute to static electrical 
charge build-up. However, static charges are still 
produced  when  particles  strike  other  dust  par-
ticles as they move through the duct. Since metal 
duct  is  a  conductor,  it  can  be  grounded  quite 
easily  to  dissipate  any  static  electrical  charges. 
Replace  any  plastic  dust  ports  with  sheet-metal 
equivalents, or bond sheet metal ducting to metal 
frame of machine with grounding wire.

Avoid inferior metal duct that requires you to cut it 
to length and snap it together. This type of duct is 
time-consuming to install because it requires you 
to seal all the seams with silicone and screw the 
components on the ends with sheet-metal screws. 
Another disadvantage is the rough internal seams 
and crimped ends that unavoidably increase static 
pressure loss.
