The firm Nanogate AG, Quierschied, is developing improvements for filter material with a reduced fiber thickness and thus higher air permeability. By means of an equipage which combines an established binder matrix with functional electret particles, the filters achieve a substantially improved filtering capacity with practically unaltered air permeability, and thus low energy consumption, in operation.
The processing of the filter material with the new permaStatic® equipage leads to a complete thin sheathing of each individual fiber. The result: with stable unchanged fiber thickness, and thereby unaltered air permeability, the deposit level is increased markedly, especially in the fine particulate content. No augmented pressure drop is necessary between the in- and outflow sides of the filter to achieve a better filter efficiency.
Compared to unprocessed polypropylene fleece, the filter capacity could be improved in the fine particulate range by up to 60% with permaStatic® equipage. In addition, the binder matrix makes the filter material distinctly more water- and oil-repellent and thus renders the electrostatic charge more independent of ambient conditions such as moisture and temperature. An extended service life, as well as better removal of deposits during operation, are further advantageous results.
