1 Moisture separator (if fitted) – 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 Fabric filter elements (inserts and bags) – Before removing the filter elements,
cover the base with some suitable material to avoid the dust falling into the
valve exhaust port. Remove the jet tubes, then remove each filter element
and check the general condition of the bag. Clean each bag using a vacuum
cleaner. If the dust is of an abrasive nature it is advisable to examine the
elements more frequently.
Bags showing holes must be replaced. Place used filter bag into
a sealable bag and dispose properly.
If in doubt regarding the safe disposal of the used filter bag,
consult your local regulations.
Any dust falling into the valve exhaust port should be removed before
restarting the collector.
When refitting filter elements, tighten bottom clamp first. Do
not over-tighten. (Recommended maximum torque 20 ft-lbs f or
27 Nm).
5 Jet Tubes – Check that the jet tubes are clean and that the jet orifices are
clear.
6 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.
7 Antistatic earthing (if fitted) – Check collector earthing continuity.
8 Explosion risks – Check measures taken to avoid ignition sources are still in
place.
