Problem
Drop in filter
efficiency
Pressure
differential is
too high
17
Probable cause
Air volume too low
or to high
Filter envelope not
suited for dust to be
filtered
Filtered air
temperature is
higher than normal
Static electricity
builds up in collector
Air volume is too high
Ineffective cleaning
system
Humidity clogs the
filter envelope
Presence of dusts in
clean air ducting
system
Presence of static
electricity within
the collector
Incorrect rotation
speed of fan/motor
assembly
Solution
Check for speed and motor rotation, the position of
gates and air volume at collector outlet. Make necessary
adjustments to obtain original specifications.
Replace filter envelope with a filtration system
according to the dust entering the system.
Check temperature of air to be filtered. Bring necessary
adjustments to obtain satisfactory temperature.
Check for appropriate grounding wires of collector,
components 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.
Check for speed and rotation of motor, the position of
gates and air volume at collector outlet. Make necessary
adjustments to obtain original specifications.
Increase frequency or duration of cleaning sequence.
Check cleaning system.
Lower humidity level and replace filter envelope if
damaged.
Clean ducting system, check seals and replace if neces-
sary. Look for filter envelope leaks and check for dust on
clean air side of collector. Replace filter if necessary.
Ensure grounding wire is connected. Increase relative
humidity of air to be filtered if lower than 50% R.H.
until the dust to be filtered is affected.
Check for fan/motor rotation and correct.
