Medium efficiency bag air filter media is made of polypropylene melt-blown non-woven fabric and spun bond fabric. The high-temperature melt-blown process uses a stable electret and proven composite technology. It is a premium material with a 3D mesh structure which includes two different layers for coarse and fine filtration and an enhanced layer. It meets the requirements of multi-layer and gradient filtration for extended service life.
