Regarding filtration efficiency, Crystar® air filters can provide retention levels from 80% to 100% for aerosols in the range of 1 to 10 µm (according to EN 14683 AC – surgical grade masks). The assessment of retention performance based on ISO 16890 is currently in progress.
In terms of resistance to air flow, Crystar® aFT media is inherently very permeable. By a proper selection of the filter thickness, area and microstructural properties, pressure drops can be minimized in order to reduce the energy consumption related to the filtration process.
Crystar® aFT are available as flat boards with a thickness range from 4 to 40 mm. Special shapes can be machined to meet specific requirements regarding the filtration medium integration and use.
