Air sterilization – about Veit AC 10 / AC 20


Did you know that UV-C air sterilizers are one of the most suitable methods of air purification? Because the air you breathe matters and your health is at the forefront, we suggest you use an air sterilizer to eliminate the risk of respiratory infections and to clean the air of viruses and bacteria carried by it. We invite you to read this article to find out different methods of air sterilization, what UV-C radiation is, how it works and how air sterilizers manufactured by Veit can help you.


Prior to the pandemic and the widespread understanding of the harmful effects of breathing air laden with viruses and bacteria, air sterilization was mainly used for two groups of operations:


  • for performing aseptic (sterile) manipulations, such as in certain bacteriological or pharmaceutical processes and in operating rooms;
  • for aeration of antibiotic fermentation – where although a certain purity of air is required, air does not need to be completely sterile.


The methods used for air sterilization can be classified as follows:


  • radiation treatment – ultraviolet or gamma rays;
  • thermal treatment;
  • electrostatic precipitation and filtration, etc.


Knowing the importance of UV – C rays for the air sterilization process, the Veit group has created and perfected the range of AC sterilizers, wich sterilize the air quickly and efficiently, eliminating up to 99% of bacteria and viruses from the air. Because we have your well-being as our customer always in mind, we also thought about eliminating the harmful effects, so AC sterilizers work without chemicals and ozone.


What are UV-C rays?


  • UV-C is ultraviolet radiation below a wavelength of 280 nm, which is not visible to the human eye;
  • Germs, bacteria and viruses are reliably reduced and hygiene and storage conditions are improved;
  • UV-C light has been used for over 40 years to disinfect air, surfaces and water;
  • UV-C has the greatest effect at a wavelength of 254 nm. This is the range of UV-C lamps we use (low pressure lamps, lifespan approx. 9,000 hours, emission power 95W per lamp).


With the help of AC air sterilizers – you can disinfect the air 24 hours a day, 7 days a week, because UV-C radiation does not escape from the device, so they can be used even with the presence of people in the room. We can ensure this through our intensive tests and measurements performed in Veit’s R&D development laboratory.


How do Veit AC air sterilizers work?


A powerful fan directs the air from the room through the dust and dirt filter to the device, the air is then sterilized inside the device using UV-C lamps and evacuated back to the room. UV-C lamps used for air disinfection are easy to replace and have an effective life of approx. 9000 working hours when the device is used 24 hours a day, this allows the purification of the indoor air for a whole year. UV-C rays remain trapped in the device due to the metal case and the special labyrinth inside it, the device can be used to sterilize the air even with the presence of people in the room. Veit sterilizers work without the addition of chemicals, thus eliminating the harmful effects associated with them, AC sterilizers are available for mounting on the ceiling or as mobile units, independent, depending on the size of the space used and the work carried out in it.


How does air sterilization and Veit AC sterilizers help you?


Using UV-C radiation, Veit sterilizers inactivate airborne pathogens and microorganisms such as mold, bacteria and viruses, reducing indoor air pollutants. As the air is forced through the device, it passes the UV-C lamps, which directly attempt to disinfect the air by germicidal irradiation. The biggest safety concern is that ozone can be generated during this process. Veit took care of this aspect, so the sterilizers work without chemicals and do not generate ozone.


UV-C light is responsible for the main disinfecting activity of air purification systems. All that extra energy can actually change the molecules that absorb it, and DNA is particularly susceptible to these changes. Ultraviolet light bombards the microorganisms around the UV lamp and damages the DNA they need to live.


Let’s take bacteria as an example – because bacteria are a single cell, they rely on their DNA to live. This is the principle behind UV-C air sterilizers. If the DNA of a bacterial cell is damaged enough, it triggers a self-destruct mechanism, making it harmless. This way you will breathe clean air and you will have fewer health problems.
