Needle Felt Filter Media

Needle felt filter media offered by Xiwang are designed to deliver high filtration efficiency, long service life, and stable operating conditions in industrial dust collection systems. Our product portfolio includes a wide range of material and surface treatment options developed to suit different process conditions and dust characteristics.

Thanks to modern needling technology, our needle felt filters feature a homogeneous fiber distribution, providing high dust capture performance with low pressure drop. They maintain mechanical strength even under demanding operating conditions, increasing the overall reliability of filtration systems.
