Dust Collectors - Series CPV
Filter pack resistance can be checked by connecting a U-tube manometer or
differential-type pressure gauge to tapping points on the collector body (see
figure 5). This will give a continuous indication of the state of the filter packs. (On
the IPC (DR) Controller, filter resistance is shown on the LED; on the TCB, filter
resistance is shown on the LCD). Once running, the operating resistance will be
relatively stable, the actual value depending on the air volume and the characteristics
of the dust being handled.
Ignition minimising fans are fitted with a lining inside the casing. As this may
only offer protection for a limited period, any upset condition leading to rubbing,
the fan must be switched off immediately and the condition corrected.
It is recommended to periodically inspect the general casing integrity.
Do not operate above recommended compressed air pressure. Excessive
pressure will reduce the working life of components.
Servicing schedule
A record of all pressure checks should be kept in a log book to aid the speedy diagnosis
of faulty operation.

Weekly
1. Open the valve at the bottom of the moisture separator bowl and allow the
collected water to drain off, then close the valve.
2. Connect a manometer to tapping points (refer to Routine inspection) and measure
the pressure drop across the filter packs.
Monthly
Check operation of solenoid and diaphragm valves.
It may be necessary to check the operation of the valves while the system is
pressurised. Care should be taken to avoid injury.
