DWMC FUSION™ SeriesWound / Melt Blown Filter Cartridges

AJR Filtration DWMC FUSION™ Series liquid filters, formerly from Delta Pure Filtration, feature melt blown media on the inside for confidence and precision string wound media on the outside for performance. By fusing melt blown and string wound technology into the same filters, AJR Filtration can help customers achieve longer filter life and cleaner fluids. 

These filters have a rigid inner core to provide strength, a polypropylene (FDA listed per 21 CFR 177.1520) melt blown downstream section to provide enhanced contaminant retention, and a string wound upstream section for pre-filtration. An FDA compliant polypropylene wound section is available.

The  DWMC FUSION Series of filters offers a flexible format: a choice of melt blown section rating, string wound section material, and string wound section rating, so that a filter can be tailored to each unique process. A variety of end fittings enables installation into most any type of filter housing.

A DWMC FUSION filter can be a magic bullet for solving a challenging contamination problem, improving process efficiency, and lowering filtration costs.
