4. Operating Life/Durability of the GEA Explosion Protected Bag Filter Multisack G85 EX
PR-2009-0117-GB • Subject to modifications • Status 09/2009
•
Make sure that the planned installation location is suitable for the operation of the GEA
explosion protected bag filter. This comprises the following:
– The classification of the installation site as a hazard zone according to RL 1999/92/EG
– Availability of a company internal document on explosion risk protection in accordance
with RL1999/92/EG and the occupational safety codes and regulations.
•
Remove the GEA explosion protected bag filter Multisack G85 EX from its packaging outside
the explosion risk zone:
– Handle the bag filter with care and do not damage the filter medium
– Inspect the bag filter for any external damage and check if the grounding set is complete
(operation manual and explosion protection label); if the filter is damaged or the grounding
set is missing - the filter may not be mounted.
•
Loosen the old grounding set from the unit.
•
Remove the old bag filter including the grounding set.
•
Carry out all necessary cleaning of the unit.
•
Insert the new GEA explosion protected bag filter Multisack G85 EX in the unit and secure
the filter using filter retainers.
•
Screw the grounding electric cable with a ring tongue lug to grounded unit component
together (e.g. filter retainer, slide in frame, monoblock etc.) in such a way that self or
accidental removal without a tool is impossible.
An electrically conducting connection between air filter frame and unit component must be
ensured!
•
Check the ring tongue lug for secure seat.
•
Check electric resistance between filter frame and unit component using an ohmmeter – no
matter where the measuring point is - electric resistance may not exceed 1 MΩ
The characteristics and features of the GEA explosion protected bag filter Multisack G85 EX are
the same as with conventional bag filters of the same type and same configuration.
•
Replace the bag filter when the maximum allowed end pressure difference is reached. It can
be assumed that the maximum allowed end pressure difference amounts to a standard value
with initial pressure difference plus 100 Pascal of pressure drop increase. Refer to section
"1. Technical Data" for the effective maximum allowed end pressure difference.
•
Moreover, consider the recommendations of the hygiene directive SWKI 2003-5 and VDI
6022 in terms of the maximum service life.
