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

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%.




Filters more than 99.95% of aerosols and viruses.


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 attenuation.


Low energy consumption, thanks to a high efficient EC fan.


Easy and fast commissioning (Plug & Play).


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.



The ideal purifier for any building

The devices perform air sterilization to eliminate viruses, bacteria and fight coronaviruses. They purify the air, work quietly, efficiently and provide a high rate of air exchange. They are extremely suitable for work in doctors’ offices, hospitals, waiting rooms, offices, shops, schools, kindergartens and public buildings.

Conference halls and event halls

Training halls, auditoriums

Shops, Malls, Various trade sites


Air sterilizer that purify the air up to 99.99%

Primary filter

The first phase is mechanical separation of the solid contaminants by air filter еРМ10 50% (ISO16890)

Air filter НЕРА Н13

The second phase is the capture of aerosols and viruses through a HEPA H13 air filter.

ЕС ventilator

High efficiency brushless electronically commutated fan with smooth control 0-10V (0-100%). Energy efficiency class IE 5.

UV-C radiation

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.


Integrated control ready for standalone installation – Plug&Play. Counter of working hours for the UV-C lamps, smooth control of the fans, signalization for dirty filters, emergency alarm signalization.

Sound attenuation

Extremely quiet operation of the devices is guaranteed, thanks to the sound insulation of the casing and built-in resonating panels.


“Adapting the activities of SMEs in the context of COVID-19”

TANGRA AirSterilizer 07 air purifiers can be funded by European programs for improvement of the working environment and adaptation in the context of Covid-19.
