The 350PSFN0040 to 1000, 350PSF0130, and 0150 type block-mount filters utilize advanced filter materials to adsorb fine particles, with high dirt-holding capacity due to their large filtration area. They offer chemical resistance, high collapse resistance, filter grids from 3 μm to 100 μm, a mechanical-optical maintenance indicator, and a flow-optimized design developed using 3D technology.
