Virus-free air at ISH digital 2021
Ludwigsburg/Sprockhövel, February 11.02.2021 – Innovative technologies to return to everyday life: MANN+HUMMEL has developed effective methods and equipment to reliably clean indoor air. The filtration expert from Ludwigsburg will present its solutions at ISH digital 2021 (March 22 to 26) to a wide trade fair audience. The MANN+HUMMEL product portfolio comprises air filters for HVAC systems as well as mobile and stationary air purifiers. Each HEPA air filter installed (individually tested according to ISO 29463 and EN 1822) is equipped with an especially energy-efficient ePTFE medium, and is capable of safely filtering out more than 99.995 percent of viruses, bacteria and micro-organisms from the air. This means they are making an important contribution to tackling the Coronavirus pandemic.
HEPA H13 and H14 air filters for HVAC systems
The Nanoclass Cube Pro membrane has been developed for central HVAC systems. In the cold season, the HEPA filter allows the system to return to its most energy-efficient air circulation mode, thereby ensuring cleanroom-quality air. Its new ePTFE medium reduces the pressure drop by 50 percent compared with micro-glass fiber media HEPA filters, thereby bringing the operating costs of a heating and ventilation system back to a level comparable with a ‘pre-Coronavirus’ filter configuration. The filter is available in standard sizes, and can be installed without system modifications. This filter also meets the requirements of fire protection class E, as per EN 13501.
Mobile and stationary HEPA room air purifiers
Room air purifiers with ePTFE H14 air filters are another effective solution in the fight against the pandemic. The MANN+HUMMEL product portfolio consists of the stationary OurAir SQ 2500 for rooms up to 200 square meters and the OurAir TK850 mobile air purifier for rooms up to 70 square meters. The new OurAir SQ 500 for rooms up to 40 square meters has also been added to the range of solutions and will be available in March. The high-performance devices are especially quiet and have a modern design. Infectious virus particles which can attach to aerosols, such as SARS-CoV-2 for example, are almost completely filtered from the air (more than 99.995 percent) along with bacteria and microorganisms.
Recent measurements, carried out by the Institute for Mechanical Process Technology and Mechanical Systems (MVM) at KIT Karlsruhe, including in the classroom of an elementary school, demonstrated the high efficiency of the devices in terms of reduced aerosol concentration and therefore reduced risk of infection from viruses and bacteria. The studies provided evidence that it was possible to reduce the aerosol concentration in the room by 50 percent within four minutes, and by 90 percent within 15 minutes.
Applications for the HEPA air purifiers are extremely wide-ranging, and extend across all environments where large numbers of people meet or spend time together: Kindergartens, schools, universities, senior and care homes, office buildings, food retail, stores, event locations and transportation.
Decades of experience in filtration for cleanrooms and operating theaters
MANN+HUMMEL has more than 60 years of know-how in the cleanroom filtration sector (HEPA), and is the global market leader in surgical air filtration. The company, headquartered in Ludwigsburg, Germany, has specialized in especially sensitive areas for many years.
HEPA air filters and air purifiers also make sense long-term, since not only do they filter the SARS-CoV-2 virus from the air, but also influenza and cold viruses, as well as free allergens. This means occupants can continue to ‘breathe easy’ even in the post-Coronavirus era.
