Filters

Aircraft filters and replaceable filter elements are catalogued here by exact designation and recorded working medium. The range contains hydraulic, fuel, oil and air-cleaning positions used in documented aircraft, helicopter and related aviation systems. Similar housings or family names are not sufficient for selection because the internal element, filtration characteristics and connections can differ.

Filter families are separated by exact designation

The catalogue includes 11GF hydraulic-filter families, 11TF fuel-filter positions and other numbered filters or elements. Variants carrying BN, SN, M or other suffixes remain separate records. A neighbouring model must not be treated as a replacement merely because its dimensions or external form appear comparable.

Working medium and installation determine the match

Identification may require the medium, assembly location, flow direction, filtration grade, pressure range, thread or flange and the distinction between a complete filter and a replaceable element. Use only the parameters documented for the exact number. Compare the removed item and its label with the aircraft parts catalogue or maintenance documentation.

• record the complete filter or element designation;
• identify the working medium and system;
• state whether a housing or insert is required;
• provide connection and dimensional data when documented;
• add quantity, photographs and document requirements.
