needling punch filter felt®-Needle Felts - the right filter media for every possible application

RongFeng chemical enviromental protection equipment co.,ltd. offers you a comprehensive range of needling punch filter felt®-needle felts. These are usually made of a fibre layer and a supporting scrim. Due to the multi-layer fibre construction and the supporting scrim,needling punch filter felt®-needle felts are extremely compact, stable and mechanically robust.

Every scrim and fibre type has unique thermal, physical and chemical properties that are decisive for the performance and operational life of the needlona®-needle felts. In addition, the ways of combining the different scrims and fibre types into a needlona®-needle felt are almost unlimited. Based on decades of experience, our specialists from the Process and Application Technology match scrims and fibre types to your individual filtration process. This allows us to offer you needlona®-needle felts, which are exactly tailored to the technical requirements of your dust collector.

Many production steps and needling processes with our modern machinery are needed to turn fibres and scrims into a needlona®-needle felt. The needle felt is subsequently further mechanically processed, for example, smoothed, calendered and then heat set. Afterwards, the needle felt can be refined with a surface or protective finish.
