GDED-IOM-215-A
Cause:
Cartridge won’t clean through pulsing
Solution: Cartridges have a finite life. Eventually the dust can become deeply embedded
or adhere to the media so that even the most vigorous pulsing will not recover
an acceptable permeability. Replace with a new set of AAF cartridges.
13.2
Visible Discharge (emission to atmosphere)
Issue:
Damaged cartridges / damaged gaskets
Solution: Check gaskets on the cartridge and door to ensure good condition and no leak
points. Check cartridge media for holes or damage for possible paths of bypass.
Perform a leak test with dye if needed.
Issue:
Air/dust bypass through filter access door.
Solution: Ensure filter access door knob is tightened fully and the gasket appears to be
air tight. Perform a “paper test” by trying to slide a piece of paper between the
gasket and unit surface. If a piece of paper can easily fit, air and dust will
escape. Tighten the knob as necessary.
Issue:
Non-standard cartridges fitted
Solution: Replace with AAF supplied replacement cartridges
Issue:
Over-temperature excursion has occurred
Solution: Investigate damage to cartridges and gaskets and replace as necessary.
Investigate cause and consider replacement AAF cartridges with a higher
temperature rating
13.3
Insufficient Extraction
Issue:
Fan Problems
Solution: Consult Fan IOM
Issue:
Duct / damper problems
Solution: Consult system supplier
Issue:
