Melt-blown Filter Cartridges
Melt-Blown Filter Cartridges are polypropylene depth filter elements constructed from thermally blown microfibers into multi-layered gradient density media. They deliver progressive depth filtration, high dirt-holding capacity, stable pressure drop, and wide chemical compatibility for industrial liquid filtration. Ideal for RO/UF prefiltration, municipal and industrial water treatment, sediment control, and general process liquid clarification. Their layered depth matrix holds particles throughout the media rather than only on the surface, extending service life while reducing operating cost.
Melt-blown cartridges consist of multiple layers of melt-blown microfibers with a controlled gradient density — coarser fibers on the outer layers transitioning to finer fibers inward. This structure:
The melt-blown production process uses high-speed air to extrude molten polypropylene into fine fibers that collect on a rotating mandrel, forming a porous, depth filter medium with graded pore sizes.
Unlike some wound or media-bonded filters, melt-blown cartridges involve thermal bonding without adhesives or lubricants, reducing the risk of contaminants from the media itself — a benefit especially valued in food, beverage and potable water applications.
Progressive pore sizes enable superior dirt loading and more consistent ΔP profiles.
Typical ratings span 1–120 μm, adaptable to different prefiltration needs.
Excellent chemical compatibility with acids, bases, solvents and common process fluids
Available in a broad range of lengths and outer diameters to fit standard housings.
Depth retention and high dirt holding reduce frequency of change-outs.
Even contaminant loading extends usable life and maintains system efficiency.

Melt-blown cartridges excel wherever depth retention and sediment control are required:
They serve as effective prefilters in municipal and industrial water systems, removing suspended solids, dirt, rust and sediment to protect downstream equipment.
FDA-certified polypropylene media ensure no taste or odor transfer, making these cartridges suitable for process water, beverage clarification and CIP lines.
Robust PP chemistry handles a range of mild corrosive fluids, plating solutions, photographic liquids, inks, and many industrial process streams.
