TROUBLESHOOTING THE DUST COLLECTOR (continued)
II. Extremely Low Pressure Drop
A. Pressure Gauge
Check the differential pressure gauge or manometer and the tubing leading
to the dust collector as in I-A of this section.
B. Holes in Filter Bags or Bags Incorrectly Installed.
Inspect the filter bags for holes, rips, tears, or excessive wear. Make sure
that the filter bags were installed correctly according to the “Bag & Cage
Installation” section.
C. Ductwork and Dampers
Inspect the ductwork to and from the dust collector for air leaks or blockage.
Make sure that any dampers in the system are correctly positioned to allow
air to flow through the dust collector.
D. Leaks in the Housing
Check the tube sheets (flat steel sheets from which the filter bags are
suspended) and the dust collector housing for holes, cracks or loose
gasketing that would permit air to bypass the dust collector or filter bags.
III. Continuous Flow of Dust in the Clean Air Exhaust (Primary Dusting)
A. Holes in the Filter Bags or Bags Incorrectly Installed
Inspect the filter bags as in II-B this section.
B. Holes in the Tube Sheets
Check the tube sheets for holes, cracks, or loose bolts that would permit
dusty air to bypass the filter bags.
IV. Puff of dust in the clean air exhaust after each pulse (secondary dusting)
A. Worn filter bags
Inspect the filter bags for wear. Thin bags may not stop fine dust when
flexed by a compressed air pulse.
