Maintenance
Filter elements are subject to wear. In order to maintain system efficiency, optimal performance and
best air quality, these rules of proper maintenance should be followed:
PI, PN25 and PN5 filter element can be cleaned with ultrasonic bath or with back flushing.
Intervals of cleaning depend on application. If necessary replace filter element with new one.
Replace PP, PR, PM, PS filter at least element every 12 months or when pressure drop reaches
350 [mbar].
Replace PA filter element at least every 6 months.
The housing O-ring can be damaged during filter element change. To prevent air leakage and
malfunction replace housing O-ring if necessary. For replacement contact manufacturer.
Damaged components are to be replaced by new ones. If a marked degree of damage is found,
the entire filter is to be replaced.
Filter has been designed for a life of 10 years in normal operating environment. After 10 years
periodical checks of filter integrity are strongly recommended for safe operation.
Carry out a check for leaks once the maintenance work has been finished.
