The 245PSFN0040 to 0400, 245PSF0130, and 0150 block-mount filters stand out for their highly effective filter media, adsorbing fine particles, high dirt holding capacity due to the large specific filter area, chemical and collapse resistance, ideal for cold starts. They offer filtration grades from 3 to 100 μm, a standard mechanical-optical maintenance indicator, and a flow-optimized design thanks to 3D computer-aided development.
