The ebm-papst fan draws the air in the room into the bottom of the unit, creating air circulation.
The fan circulates 50 m³ of air per hour through the ætaire. Depending on the size of the room, the fan can be set to 25 or 50 m³ per hour.
- Sound at 25 m³ = 25db (very quiet)
- Sound at 50 m³ = 28db
To compare:
• Recording studio: 30db
• Refrigerator: 45-50 db
• Coffee-maker: 50-60db
• Traffic: 70db
• Vacuum cleaner: 60-85db
The ionizer introduces 8.5 million negative ions per cubic centimetre into the air. Most of the dust particles in an enclosed space normally have a positive charge. Negative ions have the effect of attracting positive dust particles.
By adding negative ions to the air, the positive particles in the air become heavier, which causes them to sink towards the ground. The process therefore results in cleaner, dust- and pollen-free air.
At places where the air is clean, the air contains many more negative ions. Here are some examples of the great number of negative ions in various surroundings, per cm3:
- Waterfall, forest: 50,000
- Mountains, sea: 5,000
- Outskirts of a city, meadow, field: 700-1,500
- Park in the city: 400-600
- Sidewalk: 100-200
- Home in the city centre: 40-50
- Enclosed office with air conditioning: 0-25
The air passes through the 3M High Air Flow (HAF) filter. This special filter contains an antimicrobial film layer that prevents the growth of various infectious substances on the filter.
The antimicrobial media slows the rate at which the filter 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 filtered out by the 3M filter.
After passing through the filter, the air is exposed to the UV-C sanitising light. The special Philips UV-C lamp in the ætaire produces ultraviolet radiation at a wavelength of 253.7 nm. This UV-C light kills bacteria, viruses, moulds and other primitive organisms. The radiation destroys the DNA structure of micro-organisms and prevents their reproduction. This method even works if the micro-organisms have become immune to other disinfection methods. Your air will be disinfected in a safe and efficient manner, and you will enjoy excellent air quality.
Technical specifications Philips TUV PL-L 60W/4P HO lamp
- TUV PL-L 60 Watt
- UV-C output 19 Watt
- Dose 4,23 mJ/cm2 (Flow 50m3/hr)
The ætaire includes an integrated hours counter that accurately keeps track of the number of hours the lamp has been on. You know exactly when the lamp and the filter are due for replacement. With the timer you can set the ætaire to operate at the desired speed during each hour of the day. For example: In a bedroom, the ætaire doesn’t have to run at 50 m3 per hour during the night; 25 m3 per hour is more than adequate. In the family doctor’s waiting room, full speed is probably the best choice. So, you see, the ætaire can be set to accommodate any room or situation.
The special aluminium interior of the housing results in extra reflection of the UV-C radiation. This increases the efficiency of the UV-C by up to 50%. The reflection exposes the micro-organisms to the deadly UV-C radiation from every direction, maximising its effectiveness.
The exiting air has been 90% filtered, ionised and disinfected. Clean air in your living environment is better for your health: it increases your body’s resistance, it relieves or eliminates respiratory allergies, and fears and depression subside or disappear. The most important effect is that illness can be prevented.
