Deltaflow filter cartridge is a high flow PP melt blown filter cartridge without core. It is fusing and intertwined of polypropylene resin without any chemical glues.The cartridges are glued at random to form 3D micro pore which will make the cartridge 3 layers with fine fibers in surface and coarse fibers and deep filtration.Large diameter extend to very high filtration surface area and high flow rate.This insures to reduce the number of filter cartridges and dimension of housing required. The long service life and high flow rate result in low investment and less manpower in many applications.
