As the nanofiber technology advances for filtration, we have found a great use of nanofiber for fuel and oil filtration. With the proper media design, nanofiber composite media can achieve high filtration performance with safe and environmental friendly features at the same time.

We utilize fully synthetic nano- and ultra-fine fibers free from glass fiber and adhesive resin and PFAS. By a gradient structure design as shown below, we achieve high-performance liquid filtration materials.

There are several advantages we can take from nanofiber technology. The first is the nanofiber allow us to design media that has high filtration efficiency and high dust loading capabilities at good pressure drop, for example we can achieve 2um efficiency at 230g/m² DHC at permeability of [...]. Even under real operating conditions involving vibration and flow rate variations, the nanofiber material maintains consistently high efficiency with no performance degradation, offering the best solution for advanced high pressure common rail (HPCR) engine protection.

The second is that we can achieve higher efficiency at the full spectrum of particle sizes, such as 30mm grade nanofiber media, it not only has high efficiency of 99.9%@30mm, it also has efficiency of 95%@15um, 65%@10um, 35%@5um—significantly outperforming that of wet-laid synthetic media (75%@15μm, 45%@10μm, 20%@5μm) and cellulose media (60%@15μm, 30%@10μm, 8%@5μm), while operating at [...]
