Dirt Defence Filter (DDO) are designed for the efficient and continuous removal of solids such as rust, sand and other particulates from aviation fuels.
FAUDI Aviation DDO-Type filter elements are primarily used in the filtration of mobile into-plane refueling. Dirt Defence Filters are an economical and reliable alternative to filter monitor elements and its associated SAP* (Super Absorbent Polymer) problem.
Dirt Defence Filters shall be used in conjunction with the AFGUARD® Electronic Water Sensor (EWS). The EWS technology becomes the data source for highest performance and service life of filter elements - we call it simply PerformanceBasedFilterLife™.
