Microfiltration

Video: Use of microfiltration membranes in the medical field

Fast and safe processes, robustness when in use, and ease of processing are all requirements that microporous membranes for filtration and venting have to meet. This is often a major challenge for the conventional sensitive membranes used. Manufacturers face technical challenges to ensure the integrity of the final product during the process and manufacturing while increasing the yield.

The patented SEFAR PURETEX® technology is characterized by embedding the membrane in technical fabrics for protection and stabilization. The use of fibers that are just nanometers in diameter literally results in billions of homogeneous pores from endless, non-shedding nanofibers that enable unparalleled flow rates in venting and liquid filtration applications. Depending on the application, the surface can be finished customer specific, so that optimized hydrophilic or hydrophobic and oleophobic properties can be achieved.

Venting and air filtration

High air or steam exchange rates, high filter efficiency, unrestricted functionality of the membrane when in contact with a wide range of different liquids, and safe and easy processability are basic requirements in the area of venting and air filtration.

Liquid filtration

SEFAR PURETEX® comes with a wide range of advantages: a high filtration performance at low counter pressure, a high particle retention, easy processability, and robustness against mechanical stress.
