Kalthoff Luftfilter - High-Efficiency Particulate Air Filter (HEPA) Panel - Brochure

HEPA (High-Efficiency Particulate Air filters) allow the almost complete separation of sub-micron particles. Ultrafine micro-glass papers are used as filter media, which are pleated to provide filter-media surfaces which are 40 to 100 times the area of the face dimension. As a result of this, an especially slow airflow occurs which supports the diffusion arrestance of the sub-micron particles. Effective pre-filtration of coarse particle fractions is necessary as mandatory.
