<p>The invention relates to a washable, non-disposable ecological filter for lubricants and fuels. Said filter differs completely from existing filters. Due to its construction and materials, one or several assemblies of filtering elements can be used, one filtering element being placed inside the other and each filtering element having differing calibration. The filters may be mounted on a lid or flat or staggered base. Each part has the necessary seals to prevent leaks. Each filtering element has an open mesh, a fine filtering mesh and rods forming a cage that does not reduce the filtering area or pressure of the flow. The filters can be easily disassembled for washing and cleaning. They can be produced at low cost and have a long service life due to the fact that the assembly of filtering elements does not break or disintegrate and must not be thrown away once they are saturated with impurities. They prevent oil, diesel fuel or any other fluid contained in the filter from spilling or being washed away by rainwater, thereby contaminating aquifers, rivers, lakes and seas, etc. The invention thus provides a fully ecological filter.</p> |
