DFSB Depth Filtration Modules

Masterfilter Depth Filtration Modules - DFSB

The Masterfilter DFSB series filter modules are available with filter media of high-purity lignocellulose and inorganic filter aid agent and high-purity cross-weaved lignocellulose and activated carbon powder. The internal porous three-dimensional structure with large internal surface area delivers excellent filtration performance and high dirt holding capacity for depth filtration applications. The filter sheets are manufactured with our highly automated proprietary process. All raw materials are controlled through our world-class quality system to ensure robust product quality and consistent filtration performance.
