DFSM Depth Filtration Modules

Masterfilter Depth Filtration Modules - DFSM

The Masterfilter DFSM series depth filter modules are composed of high-purity cellulose fibers and inorganic filter aids and with activated carbon powder through a special process. The internal interwoven three-dimensional structure delivers excellent filtration efficiency and high contaminant holding capacity in depth filtration applications. The production of these cassettes utilizes advanced and highly automated manufacturing process. All raw materials undergo rigorous quality control inspection to ensure consistent product quality and filtration performance.
