INADEQUATE
FILTER CLEANING • Insufficient air pressure.
• Faulty air diaphragm valve operation due to
foreign material from the air supply piping
(especially in new systems).
• Malfunctioning solenoid valve due to dirt in
the valve plunger.
• Faulty sequence timer operation.
• Excessively long intervals between cleaning

Clean valve, blow down lines before
connecting.
Clean plunger.
Check timer wiring.
Adjust timer potentiometer with screwdriver

UNUSUALLY HIGH
PRESSURE DROP • Excessive airflow.
• Low compressed air pressure.
• Moist air causing filter clogging.
• Solenoid valve malfunction.
• Rotary valve air leakage caused by
increased clearances due to wear.
• Blinding of filter medium due to excessive
dirt load.
• Blinding of filter medium caused by mixture
of dust and moisture.
• Blinding of filter medium due to unusually
fine or difficult dust.
• Dust re-entrainment due to hopper
overfilling.
• Defective or misadjusted sequence timer
Match system airflow to separator rating.
Ensure 90-100 psig air is constantly available
at the air header.
Eliminate moisture in air supply.
Feel for air pulses at discharge of each valve;
clean or replace valve or solenoid if faulty.
Repair or replace airlock.

Eliminate moisture in system airflow or
compressed air.

not matched to actual operating conditions.
• Localized cartridge wear caused by
excessive material buildup in hopper.
• Blinding of filter medium.
Consult Spencer Representative for
alternative filter medium.
Check dust discharge system; consider
