Norafin Industries (Germany) GmbH products

Norafin offers a variety of spunlaced filter media for process liquid and air filtration. The spunlace technology offers various product opportunities and performance advantages not only in liquid, but also in air filtration as for example in hot gas filtration. Thanks to the hydroentangling process, which binds the fibers in a homogeneous and natural way, and the finer fibers that can be used with this technique, the surface of the filter media shows an increasing number of finer pores. The improved surface of the medium as well as the homogeneous cross-section lead to better filtration efficiency.

Product tests show that hydroentangled filter media offer various performance advantages compared to more traditional materials. Thanks to the high-density fiber entanglement, spunlaced filter media demonstrate a superior uniformity of the web, which leads to increased filtration efficiency.

Norafin has recently developed a new range of self-pleatable filter media with integrated metal scrim, which can be pleated without additional treatment, which is particularly interesting for media used in high-temperature filtration. Up to now, existing high-temperature media are pleated by applying a stiffening binder. By using a binder, an additional operational step is needed, which is not easy to process. The temperature resistance of the filter media is likely to be decreased and the permeability of the material used is lowered. Norafin`s innovative spunlaced filter media has been developed by adopting a metal scrim. Thanks to the scrim used, the media can be pleated without using any binder at all. The filter media consequently have a much higher intrinsic temperature resistance and a better air permeability.
