Decontaminate and purify with AB Bio The new and innovative range of AP BIO air purifiers from FläktGroup is claimed to be the most efficient way to combat airborne transmission of viruses and bacteria in almost any closed environment. Thanks to the revolutionary AirFend™ filtration technology, viruses and bacteria are 99.99985% deactivated – including SARS-CoV-2 – when air passes through the filters in the unit. AirFend™ is a 100% natural solution. Conventional air purifiers only filter the air, without deactivating bacteria and viruses. FläktGroup has more than 100 years of innovation and experience in ventilation and air handling applications and its expertise in this area has resulted in a new technology that purifies the air in a low-pressure chamber containing an active biodecontaminating powder (AirFend™) which is bactericidal, fungicidal and virucidal. AirFend™ actively decontaminates SARS-CoV-2, but also a number of other pollutant families such as bacteria, viruses, dust, allergens and chemical vapours. This natural mixture, formulated of non-toxic plant substances, is activated through a patented electrobiological process as follows.
active air purification, unlike usual passive filtration treatments. The AirFend™ technology is used to make the mechanical filter active. The treatment is carried out by uniformly depositing a bio-decontaminating active substance in powder form on the surface of the mechanical filter, in which the water-soluble active substance diffuses on the filter media as the humidity increases. In a medical environment, the FläktGroup AP BIO air purifier, when installed in hospital rooms, intensive care rooms or laboratory, continuously purifies the air of particles, and also deactivates viruses and bacteria (including SARS-CoV-2 responsible for COVID-19), with the greatest respect for patients, caregivers and
the environment. The solution is ozone-free and non-irritating to the respiratory tract. 99.99985 % effective General efficiency levels are broadly similar for all systems incorporating HEPA H14 filtration. However, the unique AirFend™ technology of the AP BIO range ensures that viruses and bacteria are deactivated rather than simply being retained in the filter, and potentially being released during maintenance or shutdown phases of other conventional air filtration device. The FläktGroup AP BIO air purifier range is truly versatile and suitable for a variety of environments where hygienic air is important. Thanks to the four sizes and the practical casters, they are easy to move between locations. Low noise levels and compact dimensions make them ideal for all public spaces such as offices, gyms, shops and restaurants, and the perfect solution to ensure more hygienic air in these premises.
