As part of a ZIM research project, SEKO-Staubtechnik, together with two cooperation partners from research and industry, developed a filter system coated with a biopolymer-based nanofiber layer made of chitosan and silk fibroin. The innovation of the project lay in the combination of the scalable centrifugal electrospinning process for the production of the nanofibers, which have application-relevant biofunctionalities, such as increased health compatibility and temperature resistance.
The developed system achieves a separation efficiency of 99.99% with a particle size distribution of 0.2 to 350 µm and is cleaned using the jet-pulse method. The compressed air system operates with an overpressure of less than 4.5 bar, which in turn saves energy, resources and costs. The novel dust extraction system also works with special measurement technology for the continuous recording of filter efficiency via the electromechanical effect.
