Dust Collectors - Series CPC
Six-monthly
The fan impellor has been dynamically balanced and the fan assembly vibration level
should be in line with category BV-3, ISO 14694. An assessment of vibration should
be made every six months, or after a significant emission, or after any misuse and a
record kept of measured values. Excessive vibration levels should be investigated
and corrected immediately.
Vibration monitoring is mandatory on category 2G, 3G and 2D fan assemblies.
Annually
1. Moisture separator – Isolate the compressed air supply; remove and clean the
filter element.
2. Air manifold – Having isolated the compressed air supply, remove the drain plug
and air inlet connections and clean out any accumulated sludge and inspect to
any current local legislation.
It may be necessary to remove a diaphragm valve for internal inspection
purposes.
3. Doors – Check the dust seals on all access doors for damage or ageing and
ensure that they are properly seated to prevent entry of water. This is particularly
important where the collector is located outside or in a wet atmosphere.
Faulty seals must be replaced.
4. Flameproof maintenance – It is important that all flameproof enclosures, motors
and cable glands are inspected for corrosion and tightness on an annual basis.
In particularly aggressive environments, this period should be more
frequent.
5. Antistatic earthing (if fitted) – Check collector earthing continuity.
6. Explosion risks – Check measures taken to avoid ignition sources are still in place.
7. Fan maintenance – Open access door(s) and, by looking through fan inlet eye,
inspect fan thoroughly. If necessary, remove all residual dust accumulation.
(Although the fan is located on the clean side of the collector, it is possible for
low quantities of dust to migrate through the filter media).
The fan should be inspected immediately after any period of significant
dust emission, i.e. due to damaged filter media or seal etc.
The fan should be inspected immediately if there is any unexpected noise,
temperature or vibration.
The fan should be inspected every twelve months or immediately following
any misuse.
If inspection reveals any damage then the fan must not be put back into
service until properly repaired or replaced.
