Pure air for road safety.
Like a vacuum cleaner the ventilation system of a motor vehicle draws in about 300,000 liters of air per hour, together with all the exhaust fumes, pollutants, allergens and odors from the immediate environment. According to studies, the exposure for passengers is five times higher than at the side of the road. Awareness of the importance of indoor air quality to health and driving safety has increased again since the Corona pandemic.
The newly developed Blue.ion electrified cabin air filter from Hengst achieves particularly high separation rates at FFP-2 level thanks to an upstream ionizer. It thus reliably protects vehicle occupants from ultra fine dust, bacteria and viruses. In addition, the polarization of the filter ensures constant filtration performance over the entire filter service life. Thanks to its space-saving design, the system can also be retrofitted into existing installation spaces.
The design of cabin air filters is always confronted with the conflicting goals of combining low flow resistance and filtration of the finest particles (PM1 and smaller) in a given installation space. Particularly with the HEPA filters currently in vogue, this conflict of goals is solved at the expense of installation space or blower performance.
The new Blue.ion cabin air filter from Hengst impresses with its permanently high and at the same time energy efficient filtration performance, which is achieved by a combination of ionization of the particles in the air stream and polarization of the filter medium.
In detail, this means that the ionizer developed by Hengst is located directly in front of the cabin air filter. It achieves a uniform charging of the particles in the air stream in a very small installation space. The electrically charged particles can be better separated by a specially selected filter medium.
In addition, the charged particles partially form agglomerates, which are better separated in the filter due to their size. Due to the effects of ionization described above, filtration performance can be achieved that can otherwise only be achieved by filters with significantly higher flow resistances.
Meanwhile, polarization ensures that the improved filtration performance is maintained at a constant level over the entire service life of the filter.
✓ Filtration performance at FFP2 level
✓ constant filtration performance over the entire filter service life
✓ easy integration into existing installation spaces
