Operation
NOTE: The Air Filtration Unit is designed to
remove airborne non-metallic dust particles; it is
not designed to take the place of a dust
collection system.
Larger particles are trapped by the outer filter.
Smaller particles are stopped by the fine mesh
pockets of the inner filter. The air is then
exhausted through the diffusion filter, which has
a fibrous composition to help diffuse the air.
Changing Filters
Refer to Figure 1.
Turn off, disconnect (unplug)
the Air Filtration Unit from the power source
before servicing or changing filters.
There are two filters that need to be cleaned
and/or replaced periodically, depending upon
the amount of use and the environment of your
shop. Using clogged filters will diminish the
overall efficiency of the unit.
The outer filter is disposable, but its life can be
extended by occasional use of a shop vac or
compressed air to clean off the dust. For
maximum efficiency, however, a dirty outer filter
should be discarded and replaced with a new
one. (An optional, washable outer filter is
available – stock no. 1791085.)
The inner filter can be blown out with air or
washed out. (Allow to dry before re-installing.)
The diffusion filter will not need replacing. It
should be inspected occasionally, and if needed,
cleaned by light vacuuming or compressed air.
(An optional charcoal diffusion filter – stock no.
1791084 – may be purchased, and is used to
reduce non-volatile fumes or odors.)
