Filter locationFlushing Filter• To remove particles that have been built-into the system during assembly ormaintenance before start-up.• To remove large particles that will causecatastrophic failures.• To extend 'in-service' filter element life.Pressure Line• To stop pump wear debris from travellingthrough the system.• To catch debris from a catastrophicpump failure and prevent secondarysystem damage.• To act as a Last Chance Filter (LCF)and protect components directlydownstream of it.Return Line• To capture debris from component wear oringression travelling to the reservoir.• To promote general system cleanliness.Air breather• To prevent ingression ofairborne particulate contamination.• To extend filter element service life.• To maintain system cleanliness.Kidney loop/off-line• To control system cleanliness whenpressure line flow diminishes(i.e. compensating pumps).• For systems where pressure or returnfiltration is impractical.• As a supplement to in-line filters to provideimproved cleanliness control and filterservice life in high dirt ingression systems.Additional filters should be placedahead of critical or sensitivecomponents• To protect against catastrophic machinefailure (often non-bypass filters are used).• To reduce wear• To stabilize valve operation(prevents stiction).Pressureline filterReturnline filterAirbreatherFluidConditioningPurifierOil transferfilter cartKidneyloop/off-linefilter18
