Optional Water Cleaning
Proper filter cleaning should not be neglected as a
dirty filter can significantly affect your dust collector's
performance and the overall lifespan of your filter.
1. Wear a dust mask and eye protection.
2. Rinse the filter with a water hose (40 psi maximum)
r along the filter's exterior pleating. Avoid getting
water on the inside of filter. Do not use a 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.
3. Blow excess water off using a hand-held, compressed
air nozzle with a pressure between 30 to 60 PSI along
the filter's exterior pleating. Hold the air nozzle at a 20°
angle and at least 6" away from the filter; closer blasts
may damage the filter material.
4. Dry filters prior to returning them to service. It is NOT
recommended to dry at temperatures above 150°F
(65.56°C). The filter must be absolutely dry before re-
use. Allow at least 24 hours of drying time. Protect the
filter from dust during the drying process.
5. Ensure that all moisture is gone and there are no leaks
prior to install. Re-install the filter and run the collector
10 - 15 minutes without collecting any dust.
Emptying the Drum
When first using the Dust Cobra dust collector, check
the drum regularly to get an idea of how often it
needs to be emptied. If the drum becomes overfilled,
the dust will be sucked into the collector and into the
filter.
1. Wear a dust mask and eye protection.
2. Turn off the dust collector and wait for the system's fan
blower to come to a complete stop and for the dust to
settle before slowly lifting off the drum lid.
3. Dispose of waste safely and properly.
4. Replacement bags should be 14 x 16 x 36" and at least
1.5 mils thick. See Accessories page for replacement bags
needed for your system. When you are not using a bag in
your drum then you must close the Switch Valve (G31B).

Motor brush Replacement
The Dust Cobra has a brushed motor. The brushes
have a lifespan of approximately 500-750 hours. If
you have reached the lifespan or the motor stops
operating, then it's time to replace the carbon
brushes with Part number: BRB010120. To access the
brushes:
1. Un-clamp the motor assembly from the cone assembly.
2. Unscrew the six screws shown circled in the below
image.
3. Remove the cowling and the spacer to access the motor.
