Probable cause
Solution
Smoke or dust
escaping from the
filter or around
the filter frame
Filter envelope not
installed properly
Tighten fasteners on filter frame to ensure proper seal.

Drop in filter
efficiency
High level of humidity
within the collector
Check humidity level or relative humidity within the col-
lector. A slightly higher humidity level may be corrected
by closing some gates and by shaking the filter. If the
humidity level is too high, take necessary measures to
dry the the air before it enters the collector.
Air volume too
low or too high
Check for speed and motor rotation and the position of
gates. Make necessary adjustments to obtain original
specifications.
Filter envelope not
suited for dust to be
filtered
Replace filter envelope with a filtration system suited for
the dust to be filtered.
Filtered air tempe-
rature is higher than
normal
Check temperature of air to be filtered. Bring necessary
adjustments to obtain satisfactory temperature.
Static electricity build
up in dust collector
Check for appropriate grounding wires of collector, com-
ponents and ducting system. Increase relative humidity
of air to be filtered if lower than 50% R.H. until the dust
to be filtered is affected.
