Issue:
Solenoid valve malfunction. Listen for clicking of each solenoid valve
and momentary venting as solenoid is energized.
Solution: Replace solenoid.
Issue:
Moisture/Condensation
Solution: Free moisture on the filters will inhibit dust release and cause the
system to perform poorly. Run the pulse cleaning for 15 minutes with
the fan off, if applicable. Investigate the cause of excessive moisture
and consider remedies such as elimination of rainwater in-leakage, or
water in the compressed air manifold.
Issue:
Static electric charge effects may occur with very highly electrically
resistant dusts and in very dry applications.
Solution: Switch to AAF antistatic filters.
Issue:
Non-standard filters used
Solution: Replace with AAF supplied filters.
Issue:
Filters won’t clean through pulsing.
Solution: Filters have a finite life. Eventually the dust can become deeply
embedded or adhere to the media. Replace with a new set of AAF
filters.
12.2
Visible Discharge (emission to atmosphere)
Issue:
Damaged filters.
Solution: Check filters and filter endcap to ensure they are in good condition and
there is no leakage between the filter endcap and tube sheet. Check
filter media for holes for possible paths of bypass. Perform a leak test
with dye if needed.
Issue:
Filters not clamped down properly
Solution: Ensure that the hold down mechanism is correctly locked.
Issue:
Non-standard filters used
Solution: Replace with AAF supplied replacement filters.
Issue:
Over-temperature excursion has occurred.
