Two filter technologies:
- the crimped, or “spin-on”, filter, which incorporates the filtration, bypass and non-return functions (valve)
- immersed rechargeable or cartridge filters, contained in a housing and performing only the filtration function. The housing performs the other functions.
Three types of media:
- Semi-synthetic (cellulose + synthetic fibre)
- Synthetic (polyamide)
The medium is adapted to the vehicle maintenance schedule provided by the manufacturer.
