DMB Series: Polypropylene Melt Blown Filter Cartridges

DMB Series Polypropylene Melt Blown Filter Cartridges | Delta Pure string wound filtersDMB series filter cartridges are polypropylene melt blown depth filters. Delta Pure Filtration employs 100% FDA approved polypropylene, and utilizes a multi-layered construction for progressive contaminant removal efficiency.

Our innovative production process creates a depth filter with superior performance and consistency. Standard graded density cartridges are available along with custom-gradient configurations to meet specific application requirements. DMB Series filter cartridges are available in lengths to 50” (127 cm) and various diameters to 6” (15.2 cm).

DMB Series cartridges are ideal pre-filters and polishing filters where there is a fairly wide contaminant particle size distribution. The depth filtration mechanism also provides excellent control of gelatinous contaminants. A fixed pore structure formed by the non-shedding, bonded medium prevents release of trapped particles.

The self-supporting fiber matrix enables a coreless design that is both economical and strong. The polypropylene filter medium provides broad chemical compatibility.
