Dust Collection Operation
SYMPTOM
Loud, repetitious noise, or
excessive vibration coming
from dust collector.
Dust collector does not
adequately collect dust or
chips; poor performance.
Sawdust being blown
into the air from the dust
collector.
G0508 10 HP Industrial Dust Collector
POSSIBLE CAUSE
1.
Dust collector is not on a flat
surface and wobbles.
2.
Impeller fan is damaged and
unbalanced.
3.
The motor mounting is loose.
4.
Impeller is loose on the motor
shaft.
5.
Motor fan cover is dented, causing
the motor fan to hit the cover while
spinning.
1.
Dust collection bag is full.
2.
There is a restriction in the duct
line.
3.
The dust collector is too far away
from the point of suction, or there
are too many sharp bends in the
ducting.
4.
The lumber is wet and not flowing
through the dust lines smoothly.
5.
There is a leak in the ducting, or a
series of small leaks, or too many
open ports.
6.
There are not enough open branch
lines at one time, thereby causing
a velocity drop in the main line.
7.
The ducting and ports are
incorrectly sized.
8.
The machine dust collection
design is inadequate.
9.
The dust collector is too small for
the dust collection system.
1.
Bag clamps, dust collection
bag, or filter bag is not properly
secured.
CORRECTIVE ACTION
1.
Stabilize the dust collector.
2.
Unplug dust collector, and inspect the impeller for
dents, bends, loose fins. Replace impeller if any
damage is found.
3.
Make sure all fasteners on the dust collector are
tight.
4.
Replace the motor and impeller as a set if the
motor shaft and the impeller hub is damaged.
5.
Replace motor fan cover.
1.
Empty collection bag.
2.
Remove dust line from dust collector inlet and
unblock the restriction in the duct line. A plumbing
snake may be necessary.
3.
Relocate the dust collector closer to the point of
suction, and rework ducting without sharp bends.
Refer to Designing the System, beginning on
Page 17 .
4.
Process lumber with less than 20% moisture
content.
5.
Rework the ducting to eliminate all leaks. Close
dust ports for lines not being used. Refer to
Designing the System on Page 17 for more
solutions.
6.
Open 1 or 2 more blast gates to different branch
lines to allow the velocity in the main line to
increase.
7.
Reinstall correctly sized ducts and fittings. Refer
to Designing the System on Page 17 for more
solutions.
8.
Use a dust collection nozzle on a stand.
9.
Install a larger dust collector to power your dust
collection system.
1.
Reclamp the dust collection bag and air filter bag,
making sure bag clamps are tight and completely
over the bags.
