TANGRA AirSterilizer 07 

Air purifiers reduce the spread of viruses, allergens and other contaminants indoors.



The European Center for Disease Prevention and Control reports that viral diseases as well as Covid-19 are spread by airborne pathogens. According to the recommendations published on the center’s website, by increasing the amount of clean and fresh filtered air, HVAC systems can dilute and destroy pathogens in the airways and mitigate the spread of the disease..



The World Health Organization recommends the use of HEPA filters to prevent the spread of viruses and aerosols, including coronavirus and up to 99.95%. The use of systems with HEPA filters reduces the risks of infection among occupants.




Johns Hopkins University conducted a study and proved that the corona virus SARS-CoV-2 (Covid-19) can be destroyed by proper radiation with UV-C light. Spores of bacteria, viruses and fungi exposed to UV-C light die and the air can be purified up to 99.99%.




TANGRA AirSterilizer 07 is designed as a highly effective solution for eliminating viruses, bacteria and fighting corona viruses.

Air sterilizers perform three-stage air purification:

  • The first phase is mechanical separation of the solid contaminants by air filter еРМ10 50% (ISO16890) / М5 (EN779).
  • The second phase is the capture of aerosols and viruses through a HEPA H13 air filter (ISO16890 / EN779).
  • The third phase is radiation of pathogens by UV-C lights with a wavelength of 253.7nm. and with single dose between 1.5 and 4.5J.

The air purifiers TANGRA AirSterilizer 07 work quietly and provide maximum efficiency through a high rate of air exchange. They are extremely suitable for work in doctors’ cabinets, hospitals, waiting rooms, offices, shops, petrol stations, , showrooms, factories, schools, kindergartens and public buildings.




  • Filters more than 99.95% of aerosols and viruses from indoor air.
  • Sterilizes the air by UV-C irradiation (253.7nm), which guarantees 99.99% purification.
  • High rates of air exchange.
  • Extremely quiet operation, thanks to the sound insulation of the case and built-in silencers.
  • Low energy consumption, thanks to a high efficient EC fan, with electrical efficiency class IE5.
  • Easy and fast commissioning, without the need for technical specialists (Plug & Play).
  • Long service life and efficient operation, thanks to the three phases of air filtration and sterilization.
  • Unlike other UV-C sterilizers, TANGRA AirSterilzer 07 can work while the occupants are in the room and does not harm their health, thanks to the closed UV-C emitters in the housing of the device.
  • Smart air distribution. Polluted air is being sucked in from below and purified air is being supplied to the upper part of the room, above the occupants’ heads.
  • Modern and compact design. Possibility to easily move from one room to another.


HEPA filter:

Air purifiers and sterilizers equipped with a HEPA filter (high-efficiency particulate air filter) are designed to purify a minimum of 99.95% of dust, pollen, mold and bacteria, pet dust, and all airborne particles with a size greater than 0.3 microns.

UV-C radiation:

Rradiation with a wavelength below 200nm transforms oxygen in the air into ozone, which at certain levels can be useful, but in excess of the concentration can be toxic. The UV-C emitters used in TANGRA AirSterilizer have a wavelength above 250nm and the ozone is in minimum levels.


Direct UV-C radiation can damage the skin and can cause problems in human’s health. The purifiers TANGRA AirSterilizer 07 are designed so that during operation the radiation remains in the casing and radiates only the air. The occupants are not directly exposed to radiation and their health is preserved. UV-C emitters cannot be switched on during service and filter replacement.


In Europe, people spend between 70 and 90% of their lives indoors. The air they breathe is vital. Modern buildings and construction elements do not allow natural ventilation. Thus buildings were turned into a thermos. Human health and work productivity are strongly related to the quality of the air we breathe. Children need fresh air even more than adults. Clean air helps to avoid diseases, allergies and even asthma.


Based on more than 30 years of experience in the design and manufacture of ventilation and air conditioning equipment, certified by TÜV Rheinland and Eurovent, TANGRA has created air purification and sterilization devices to help fight aerosols and viruses, including Covid-19. TANGRA AirSterilizer 07 also helps to reduce allergies and improve people’s quality of life. All this leads to higher productivity and healthier inhabitants.
