Correcting faults
Procedure following a pressure blow
Pressure blows can occur, e.g. when valves are opened suddenly. The filter
element may still be usable following a pressure blow. But you must first check it
for damage. A damaged filter element must be replaced.
►
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.
—
Remove the element and check it for damage (e.g. cracks or the like).
►
Replace any damaged element (see page 18).
Please contact the manufacturer if pressure blows occur more frequently.
Insufficient filtration capacity
If the filtration capacity is insufficient, although the filter element was replaced at
the correct intervals, then the ambient conditions of use or throughput rates may
not have been matched to the filter used. Contact the manufacturer.
