55
Symptom Cause
Solution
Replace cartridges (service life is determined by the
application)
End of cartridge service life
Consult Customer Service (1-800-479-6801)
Increase cleaning frequency
Pulse for longer duration
Perform off-line cleanings
Check performance of diaphragm and solenoids (repair)
Check performance of timer/controller (adjust or repair)
Check compressed air supply (90-105 psi)
Increase filter media area
Change filter media type
Install overbags to prevent blinding
Cleaning mechanism not properly adjusted
Consult Customer Service (1-800-479-6801)
See sections following
Low Pressure / Compressed Air
Increase pressure (85-105 psi)
Decrease duration and frequency of the pulse events
Check compressed air dryer and clean if necessary
Check for obstructions in piping
Compressed air pressure too low
Consult Customer Service (1-800-479-6801)
Check wiring between controller and pilot valves
Check tubing between solenoid valves and diaphragms
Check diaphragms (replace or repair)
Check solenoid valves (replace or repair)
Pulsing valve failure
Consult Customer Service (1-800-479-6801)
See sections following
Timer / Controller Failure
Verify controller is operational
Check for appropriate power connections
Check to see if timer is indexing to all contacts
Check output on all terminals
Check accuracy of magnehelic gauge (if applicable)
Controller timer failure
Consult Customer Service (1-800-479-6801)
See sections following
Moisture in Collector
Check for leaks in collector or ductwork
Insulate collector
Purge system after shutdown
Preheat unit before operation
Check compressed air dryer (-85 degree dew point)
Locate collector indoors
Moisture in collector
Consult Customer Service (1-800-479-6801)
Check to find type of baffle (channels, abrasion resistant
plate, or none)
Remove plugged baffle
Replace baffle with the appropriate style for application
Reduce moisture in the collection system – see above
Inlet baffle plugging, causing high inlet
velocities
Consult Customer Service (1-800-479-6801)
High Pressure Drop
Heavier dust loading than design (scalping
of product)
Check designed airflow against actual airflow, adjust
accordingly
