DMC Series

DMC SeriesPolypropylene Melt Blown Filter Cartridges

AJR Filtration offers the DMC Series of melt blown cartridges, formerly sold under the Delta Pure name. DMC series filter cartridges with a core are polypropylene melt blown depth filters. AJR Filtration employs 100% FDA approved polypropylene and utilizes a multi-layered construction for progressive contaminant removal efficiency. Our in-house 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. DMC Series filter cartridges are available in lengths to 50” and various diameters to 4.5” .

DMC 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.
