The Window to Your Fluid System's HealthAirline engineers and mechanics want to know the condition of the system fluid and to receive advance warning of any impending component failure.
The Dirt Alert diagnostic layer provides a simple way of viewing and analysing the debris captured by the main system filter element. It can assist operators in preventative maintenance, both during flight and on the ground during "Green Run" testing.
How Does it Work?The 'Dirt Alert' element incorporates a pull-out diagnostic layer of porous medium in conjunction with regular filtration medium. The diagnostic layer can be removed after a certain period in service, or after engine flushing.
The diagnostic layer can be immediately examined on site to observe if there are any large wear debris particles present. If there is any contamination present, this can then be analysed in a number of ways, such as microscopic examination, chemical analysis etc. After the 'Dirt Alert' layer has been removed it can be retained as part of the maintenance record.
