Optional Cleaning Procedure
Caution! Fine dust collected in filter is hazardous to your health! Do not breathe!
Filters are easily cleaned by removing, placing inside a plastic bag and lightly tapping on floor.
Dirt and debris will fall away from the filter. Wear dust mask when cleaning filter. For more thor-
ough cleaning, use the following steps.
1. Remove Filter from system and clean using compressed air (90 psi max.), blow the loose surface dust off of the filter,
blowing from the outside / in to prevent forcing the dust into the media pores. Keep nozzle 6 - 8” from surface.
Do not use this method when any hazardous material has been vacuumed up.
2. After cleaning, inspect Filter for damage. Do not re-use a filter with bad gaskets, dented metal parts, torn media, etc...
1. Rinse the filter with a water hose (40 psi max.) on the outside. Wash from outside. Avoid getting water on the inside of
filter. Do not use high pressure nozzle or a power washer on inside of filter. The PTFE membrane surface on the inside of
the filter is fragile and can be damaged.
2. Blow excess water off using compressed air (50 psi). Keep nozzle 6 - 8” away
from inside surface to avoid damaging membrane.
3. Dry filters prior to returning them to service. It is NOT recommended to dry at
temperatures above 150 Deg. F.
The filter must be absolutely dry before re-use.
Allow at least 24 hours of drying time.
4. Protect the filter from dust during the drying process.
5. Re-install the filter and run the collector 10 - 15 minutes without collecting any dust.
Assure that all moisture is gone and there are no leaks prior to continuing service.
2. Sharply push bar down and
hold for 5 seconds then
release. Repeat this “popping”
a few times.
3. Pull gate back down to
open suction to hose.
Frequent pulse cleaning of
the filter will keep vacuum
performance optimal.
If air flow is not restored,
check for clogs and clean
filter.
Check to make sure filter is
in good condition with no
cracks or tears or interrup-
tions in the seal.
When you replace filter,
make sure you tighten filter
only enough to make a
secure seal. If you over
tighten your filter you can
break it.
A broken filter can leak
material into the motor
and cause severe
damage!
You cannot operate the
Dust Cobra without a
proper filter in place. This
can also cause severe
damage to the motor and
will void warranty!
