Microfilters are used as pre-filters for the efficient and continuous removal of solids such as rust, sand and other particulates from aviation fuels and hydrocarbons.

FAUDI Aviation microfilters are used in refineries, terminals and airport depots, primarily as pre-filters to lengthen the service life of downstream coalescer elements in filter/water separators. FAUDI Aviation microfilters are highly efficient and thus cost effective due to their large filter surfaces area. Microfilters are suitable for filtration of lubricating and hydraulic oils.
