A revolution in air disinfection 4. UV-C sanitising light The air we inhale is one of our most important basic needs. Air is essential for us to be able to live on Earth. Clean, fresh ætaire is a revolutionary new air cleaning product. With the ætaire you have an air fi lter, After passing through the fi lter, the air is exposed to the UV-C sanitising light. The special Philips UV-C lamp in the ætaire air results in better work performance, a good mood and a feeling of fi tness and good health – you certainly know how an air ioniser and an disinfector in one professional system. produces ultraviolet radiation at a wavelength of 253.7 nm. This UV-C light kills bacteria, viruses, moulds and other relaxing a clean and natural environment can be. Air has a greater impact on our lives than we realise. You can now easily eliminate bacteria, viruses, moulds, pollens and dust particles from primitive organisms.The radiation destroys the DNA structure of micro-organisms and prevents their reproduction. the air you breathe. The air in your living environment is continuously protected, and This method even works if the micro-organisms have become immune to other disinfection methods. Your air will be Air can contain just as many good substances as bad. Our air is not equally clean everywhere we go. Infectious bacteria, you can prevent illnesses, allergies and the spread of the substances that cause them. disinfected in a safe and effi cient manner, and you will enjoy excellent air quality. viruses and moulds spread easily through the air and can make us sick. Air can also contain pollens and dust particles that can cause allergic reactions in people who are sensitive to them. We all know how easily we can catch the fl u virus 1.

Test results show that the size of the room, the fan can be set to 25 or 50 m³ per hour. This can be set per • Dose 4,23 mJ/cm2 (Flow 50m3/hr) enclosed spaces contain much more bacteria, viruses and moulds than open areas. The air in enclosed spaces is usually hour of the day. poorly ventilated and fi lled with dust, which means it also contains many contaminants. In addition to bacteria, viruses, How UV-C works moulds and pollen, air can also contain cigarette smoke, food or pet odours, and exhaust fumes. Elevated quantities of Ultraviolet light these kinds of infectious substances work as stimulating mechanisms for a range of various illnesses, of which infl uenza and are the most familiar.

The contamination of the earth, and air contamination along with it, has had our attention for a long time now. Today there DNA are international agreements in place that are intended to reduce environmental pollution. New national and international regulations and laws have also been implemented to improve the quality of the air. These measures have resulted in an industry in which new technologies are developed to clean the air in enclosed spaces. 1MGVSFI The molecular structure of the DNA is broken down rendering the microbe harmless

5. Timer 2. Ionisation The ætaire includes an integrated hours counter that accurately keeps track of the number of hours the lamp has been The air drawn in by the ætaire fi rst passes the ioniser. The ionizer introduces 8.5 million on. You know exactly when the lamp and the fi lter are due for replacement. With the timer you can set the ætaire to negative per cubic centimetre into the air. Most of the dust particles in an enclosed operate at the desired speed during each hour of the day. For example: In a bedroom, the ætaire doesn’t have to run space normally have a positive charge. Negative ions have the effect of attracting at 50m3 per hour during the night; 20m3 per hour is more than adequate. In the family doctor’s waiting room, full speed positive dust particles. By adding negative ions to the air, the positive particles in the air is probably the best choice. So, you see, the ætaire can be set to accommodate any room or situation. become heavier, which causes them to sink towards the ground. The process therefore Figure 1.1 Some examples of bacteria varieties. Figure 1.2 Bacteria results in cleaner, dust- and pollen-free air. 6. Housing The special aluminium interior of the housing results in extra refl ection of the UV-C radiation. This increases the effi ciency At places where the air is clean, the air contains many more negative ions. Here are of the UV-C by up to 50%. The refl ection exposes the micro-organisms to the deadly UV-C radiation from every some examples of the great number of negative ions in various surroundings, per cm3: direction, maximising its effectiveness. • Waterfall, forest: 50,000 • Mountains, sea: 5,000 7.

This special fi lter contains an antimicrobial fi lm layer that prevents the growth of various infectious substances on the fi lter. The antimicrobial media slows the rate at which the fi lter becomes clogged, thereby increasing its service life. Those dust particles and pollen in the air that do not settle out immediately as a result of the ionisation are fi ltered out by the 3M fi lter.
