LFX-MB™ Super Long-Life Melt-Blown Filter Bags

FiltraCore Asia’s LFX-MB™ melt-blown polypropylene filter bags are engineered for long-life depth filtration, delivering effective particulate reduction, extended operating life, and stable performance in demanding industrial liquid filtration systems.

Manufactured using multi-layer melt-blown polypropylene media with a graded-density construction, each layer captures progressively finer particles to maximise dirt-holding capacity, maintain low differential pressure, and reduce change-out frequency.

Integrated inner and outer spunbond scrim layers reinforce the media structure, supporting dimensional stability and reliable nominal micron retention under varying flow and pressure conditions. The all-polypropylene construction provides broad chemical compatibility, while a thermally welded moulded polypropylene collar ensures a robust, leak-free seal in standard bag filter housings. Designed for applications requiring high dirt-loading capacity and consistent long-term performance, LFX-MB™ melt-blown filter bags are well suited for industrial users seeking dependable, long-life depth filtration media for polishing and guard filtration duties.

FiltraCore Asia’s LFX-MB™ melt-blown polypropylene filter bags are designed as direct drop in replacements for equivalent melt blown polypropylene depth filter bags used across industrial liquid filtration. The LFX-MB™ series matches industry standard sizing, collar styles, and nominal micron ratings, allowing seamless substitution in existing bag filter housings. Representative compatible product families include:

  • Eaton® LOFCLEAR® Series

  • Parker Hannifin® FULFLO® XLH series

  • Filtration Group® melt blown polypropylene liquid bag series
