Masterfilter APKM series absolute multi-layered polypropylene cartridges combines depth filter technology with pleated filter technology, ensure high contaminant holding capacity and large filtration area. APKM construction adopts depth filter technology of graded pore-size avoiding filter surface jam. Graded pore-size distribution from coarse (upstream) to fine (downstream) can remove particles, colloids and gels gradually and extend filter’s service life.
