Polluted air is sucked in at the top inlet of the IPERJET DF TOWER and filtered by the high efficiency Class M filter cartridges up where up to 99,9% of dust particles are removed and clean, healthy air is returned in the workspace. Clean air benefits all employees in the workspace and will lead to increased production. As an option, we can provide high efficiency HEPA H13 post filters that guarantee up to 99,95% of pollutants down to 0.3 microns are removed.
