 Dust Collectors  - Series CPV

TABLE 2 – FAULT LOCATION

Symptom

Possible cause

Action

Excessive 

pressure 

differential.

Compressed air 

malfunction.

If compressor stopped, rectify compressor fault; check interlocks; 

check motor and supply; check drive.

If compressor OK, check pulses at manifold pressure gauge.

Clean filters, dismantle and clean moisture separator.

Check for excessive water or oil in compressed air supply, and 

possible accumulation in manifold.

No pulses of air to 

valves.

Refer to controller manual supplied with dust collector.

Filter packs blocked.

Run filter packs clear*, then remove each filter pack in turn and 

renew any that are damaged.

Motor speed low.

Check line voltage, phases, fan motor connections. For Star/Delta 

applications, check motor is in Delta.

Incorrect fan motor 

rotation.

Check electrical connections and transpose if necessary.

Insufficient airflow Fan motor stopped.

Check motor supply overloads, fuses and interlocks (if fitted).

Check motor connections and windings.

Filter packs blocked.

Run filter packs clear*, then remove each filter pack in turn and 

renew any that are damaged.

Ducting blocked.

Check throughout and clear.

Visible effluent in 

clean air outlet.

Filter packs not properly 

sealed.

Ensure filter pack retainers are fitted securely.

Damaged filter pack.

Damaged filter bag can be identified by the dust present in clean 

air chamber. Withdraw filter pack and renew bag. 

*To run filter packs clear, allow the controller to perform several complete cleaning cycles before 

switching off compressor etc.
