Type ERUF..P filter elements of filtration grade ST are sterile filter elements suitable for ultrafilter filter housings. They are mainly designed for separating micro-biological contaminants (sterile filtration, dry-type filtration) from compressed air flows, i.e. viruses, bacteria, etc. The filter elements can be sterilised (steaming and autoclaving) and are therefore used for generating sterile compressed air flows (sterile air). Filtration grade ST filter elements, of course, also separate finest solid contaminants and are therefore used for fine dust separation and to generate ultra clean compressed air flows (ultra clean air).

Type ERUF..P filter elements of filtration grade ST consist of a wrapped glass fibre depth filter media, supported by an addi-tional NOMEX layer inside and outside. The media pack is compactly located between two stainless steel cylinders and end caps and therefore completely integrated in the filter element.

 

To avoid a breakthrough at an early stage and to achieve a high number of sterilisation cycles, the media pack is provided with several layers. All media are located within the two stainless steel cylinders. In this way, breaking off completely or in parts of the filter layer used for filtration is impossible. 

Type ERUF..P filter elements of filtration grade ST are manu-factured using a high temperature resin bonded joint. This features allows high operating and sterilising temperatures.

All the features mentioned above are a contribution to a filter element which has a high performance (high separation effi-ciency) and maximum operating safety (integrated, multi-layer design).
