Maintenance tasks
Preparations
Make the following preparations before performing maintenance on filters.
►
When critical gases are fed:
Flush the pipe section in question and the filter with inert gas.
►
Verify the absence of an explosive atmosphere (in line with the operator’s
Directives); if necessary, cancel the EX zone first. Start work only then.
►
All gases:
—
Block gas supply to the filter.
—
Depressurise the filter housing. Make sure the pressure has been
positively relieved.
—
Allow filter to cool down.
Start work only then.
Drain condensate
Draining may be necessary several times a day, depending on the amount of
condensate produced.
►
Take appropriate measures to prevent the gas from escaping into the
atmosphere.
►
Drain the collected condensate at regular intervals and properly dispose of it.
Clean filter
ATEX-compliant filters
Dust that has collected on the filter can pose a potential risk. It is therefore vital
to regularly clean the filter. The cleaning interval depends on the dust
concentration in the ambient air. The higher the dust concentration, the more
frequently must the filter be cleaned.
Beware of static charges!
Never use dry cloths to clean ATEX-compliant filters! A static charge
could build up due to the friction. This could represent an ignition source.
Therefore: Make sure to clean the filter with a moist cloth only!
►
Clean the filter with a moist cloth at regular intervals to prevent the
formation of hazardous dust agglomerations.
►
Moisten the cloth with water only, wring out thoroughly, do not use any
detergents!
Filters not intended for an ATEX environment
►
Clean the filter with a moist cloth once a week.
►
Moisten the cloth with water only, wring out thoroughly, do not use any
detergents!
