Germany-based international filter manufacturer MANN+HUMMEL – with a local subsidiary based in Boksburg – launched a new high-efficiency particulate air (HEPA) H13 air filter in accordance with EN 1822, the new test standard for filters.
This new air filter filters more than 99.95% of viruses, bacteria and microorganisms from the supply air.
The Nanoclass Cube Pro membranes that are inside these filters, enable a return to systems using energy-efficient circulation air modes. Infectious virus particles that can attach to aerosols, such as Covid-19, are therefore reliably filtered out.
“Now is the time for facility managers and service companies to prepare their air conditioning and ventilation systems accordingly – especially with certain countries entering winter season. Air conditioning systems that run in a circulatory mode further facilitate this,” says the company.
The company notes that the filter offers numerous advantages. It is energy efficient and its new polytetrafluoroethylene – a linear polymer consisting of fluorine and carbon molecules – medium reduces the pressure drop by 50% compared to conventional HEPA air filters based on micro glass fibres.
Combined with the MANN+HUMMEL Airpocket Eco filter in energy efficiency class A+, the usual operating cost of a ventilation or air conditioning system barely differs compared with a “pre-Corona” configuration of filters, says the company.
Moreover, the Nanoclass Cube Pro membrane meets the requirements of fire protection class E according to EN 13501 – a fire classification of construction products and building elements
Since the air filter is offered in various standard dimensions, it can be used in almost any heating, ventilation and cooling system without problem and without having to convert systems, the company added.
“With the Nanoclass Cube Pro Membrane for central air conditioning and ventilation systems, MANN+HUMMEL is expanding its portfolio of solutions for virus-free indoor air in buildings. It is thus positioning itself as a development partner and complete supplier for air hygiene.”
