L82 Series - Melt Blown Filter Cartridges

L82 Series Melt Blown Cartridges are one of the standard Darlly Filter Cartridges. It is fused and intertwined with polypropylene resin without any chemical glues. The cartridge is glued at random to form 3D micro porea which will make the cartridge's 3 layers with fibers on the surface and inside. With the fiber, density from high filtration rating, strong pollutants hold capacity, low pressure drop, gradual changing structure loose outside and close inside, it can remove contaminant effectively, such as suspended substance, particulate and rust, providing efficient filtration and long service life.
