Installation, Operation and Maintenance Manual
DCE 2000 Series Dust Collectors

Any abnormal change in pressure differential across the filter elements indicates
a change in operating conditions and a fault to be rectified. For example, a
prolonged stoppage of compressed air will cause an excessive build-up of dust
on the elements, resulting in a greatly increased pressure drop.
After the fault has been rectified, resumption of compressed air cleaning will
usually return the collector to normal efficiency. However, it is advisable to operate
the controller in still-air conditions for a short period to dislodge any accumulated
dust before putting the collector into operation.
Filter resistance can be checked by connecting a U-tube manometer or differential-
type pressure gauge to tapping points on the unit casing (see Fig. 1). This will
give a continuous indication of the state of the filter. 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.
It is recommended that door fastener threads are lubricated at regular intervals
(applicable to units fitted with explosion relief).
Ignition minimising fans are fitted with a lining inside the casing.
As this may only offer protection for a limited period, if there is any
upset condition leading to rubbing, then the fan must be switched off
immediately and the condition corrected.
It is recommended to periodically inspect the general casing integrity
and support structure.
Do not operate above recommended compressed air pressure.
Excessive pressure will reduce the working life of components.
DCE 2000 collectors fitted with explosion relief should be inspected
weekly to ensure that the bursting panels are intact and clear of
obstruction. During winter, particular care must be taken to prevent
build-up of snow or ice on explosion panels.
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, if fitted, 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.
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.
