Continuous Flow of Dust in the Clean Air Exhaust
(Primary Dusting)
Holes in the tube sheets
Check the tube sheet for holes, cracks or loose bolts that would permit
dusty air to bypass the filter cartridges .
Puff of dust in the clean air exhaust after each pulse
(Secondary Dusting)
Compressed air manifold pressure too high
Check compressed air manifold pressure gauge. If the pulsing air
pressure is over 100 psig the filter cartridges may flex excessively and
allow fine dust to pass through the filter material.
Worn filter Cartridges
Inspect the filter cartridges for wear. Worn cartridges may not stop fine
dust when flexed by a compressed air pulse.
Residual dust
If dust has migrated into the clean air plenum because of an improperly
installed filter cartridge, torn filter cartridge or a hole in tube sheet, etc.,
the pulsing air may stir up the dust and allow it to escape into the clean
air exhaust after each pulse. Residual dust may also be driven down
inside the filter cartridges by the pulsing air. If the filter cartridges are
filled with several inches of dust clean both the clean air plenum and the
filter cartridges to avoid further problems.

This is often a complicated problem to diagnose and we recommend
calling the factory for advice. The following list may be helpful in
performing some preliminary checks :
