Melt Blown Media

For Prefiltration Applications

           

Melt blown media are constructed of polypropylene fibers in a graded depth structure which provides high surface areas and increased dirt capacity. The proprietary manufacturing process used in the production of the melt blown media makes efficient use of the depth structure by utilizing the entire volume of the medium. This unique process allows for the creation of multiple filtration zones while increasing or decreasing the internal voids. The multiple filtration zones function similarly to asymmetric membranes capturing particulates in specific zones of the medium resulting in efficient clarification of viscous samples and lysates. To further increase filtration capacity, the high surface area, combined with graded depth filtration, result in compatibility for pleating. The concern over fiber shedding is minimized due to the bonded and/or highly entangled nature of the fibers.

Performance

Achieve Optimal Particulate Removal with Melt Blown Media

The varying fiber diameters of the melt blown media result in graded filtration zones that effectively remove particulate matter from samples. The high surface area of the membrane provides increased dirt capacity. Large particles are captured in the outermost section of the media providing highly efficient and consistent removal of smaller particles in the innermost sections.
