Air purifier with UVC light as a stand-alone unit

Our newly developed stand-alone unit san:aer SG96 can clean the air in rooms locally. In frequently visited areas, 99.9% of bacteria and viruses including Covid-19 pathogens are inactivated the air by means of UV light. Feel safe again in your office or treatment room!

Air purifier Description – san:aer SG 96

The stand-alone unit is simply plugged in and switched on. By means of a particularly quiet fan, air is sucked into the inside of the unit at the top. The air then flows through a channel in which the 4 UV-C lamps are located. The very high-intensity ultraviolet light with a wavelength of 254 nm destroys the genetic material of the viruses in the air. This means that the viruses can no longer reproduce. The clean air is then led out of the unit at the bottom.

By sucking in the room air at the top of the unit, the air purifier offers optimal conditions for use in highly frequented locations. Air contaminated with viruses that is emitted by people can be sucked in directly.

4-fold protection of the san:aer SG96 air purifier

Our stand-alone unit offers you fourfold protection:

Frequently Asked Questions

What is the san:aer system?

The san:aer system is a device for active air disinfection by ultraviolet radiation (UV-C).

The device sucks the air inside the device through the built-in fan and disinfects it by inactivating bacteria and viruses, including Covid-19, achieving a success rate of 99.9%. Due to the active airflow through the attached fan, the san:aer unit continuously draws in the contaminated air. In the shielded interior of the unit, the sucked-in, contaminated air is led past the UV-C radiation source and cleaned without chemical additives. In the process, the bacteria, viruses and Covid-19 pathogens are killed by 99.9%. The purified air is blown back into the room.

The operation of the device is silent. The device does not produce harmful ozone.

What does san:aer in rooms?

This device is used for indoor air disinfection to inactivate the viruses and bacteria present in the air, which can prove to be harmful to health. The use of this equipment demonstrably improves indoor air and significantly reduces the risk of people becoming infected with viruses and bacteria from polluted air and contaminated aerosols.

If an infected person stays in the room, the air movement causes a distribution of aerosols in a short time. In this process, only large aerosols (droplets) sink to the ground. Due to the fact that the person emits heat, air movements occur and within seconds the exhaled particles are move. The flexible UVC disinfection stand-alone device san:aer SG 96 can counteract locally and offers an additional protection against viruses and bacteria.

How does san:aer work?

The san:aer device is a protected system consisting of a fan, air duct and UV-C radiation source. Room air is sucked into the interior of the housing, where it passes the UV-C radiation source, where the inactivation of microorganisms takes place in a permanent process.

The UV-C radiation source used has a service life of 12 to 14 months (calculated in 7-day continuous operation) and is installed in the air duct inside the unit. The emitter is easily replaceable, effective and guarantees the maintenance of the disinfection effect of the device. The technology completely eliminates the use of filtration systems, ensuring that no residues require costly disposal.

Is san:aer only good against Covid-19?

No, san:aer is not exclusively good for Covid-19. One of the main advantages is that, in addition to SARS-CoV-2, our air disinfection system inactivates a whole range of viruses and bacteria at a rate of up to 99.9%. This includes viruses responsible for several other types of diseases.

Is san:aer the only protection I need?

The san:aer device is an important component in combating and preventing the spread of pathogens such as Covid-19 pathogens, among others, in rooms where people are present. In operation, the device provides an additional and very efficient measure to effectively supplement other hygiene measures recommended by health authorities.

If the radiation source/lamp is in a closed system, how do I know it is working?

Light in bluish color is easily visible at a safe distance from the device at the front of the device through the ventilation grille.

How effective is the san:aer device against viruses and bacteria?

The san:aer device uses a UVC radiation source that irradiates the volume of treated air with enough energy to inactivate up to 99.9% of microorganisms.

The design of the housing and the built-in UV-C radiators with a total power of 96W, as well as the fan used with a circulating power of 123m³/h, ensures that the minimum-UVC-radiation dosage of 152 J/m² is applied to the air flowing through for disinfection. This is sufficient for the inactivation of a large number of known viruses and bacteria such as Covid-19, as well as influenza virus, polio virus, typhoid pathogen and diphtheria pathogen.

With a maximum air flow of 123m³/h and a radiation source of 96W, there is a sufficient dose for disinfection local areas. The air discharged from the aluminum housing afterwards is 99.9% free of bacteria.

The san:aer device is designed and built according to all valid EC directives for machines, as well as the EU directive 2002/95/EC (ROHS).

How does san:aer work in conjunction with SARS-Cov-2 and other virus mutations?

According to the tests performed, coronaviruses are among the families of viruses that are destroyed with an irradiation intensity of less than 65 J/m² due to their characteristic. In indoor environments, inactivation of Covid-19 pathogens is already achieved with 37 J/m² (see study Bianco, Andrea et al, UV-C irradiation is highly effective in inactivating and inhibiting SARS-CoV-2 replication, June 7, 2020). The effect of the UVC radiation source in the san:aer device has been tested and proven in biological tests by GMBU Jena (Gesellschaft zur Förderung von Medizin-, Bio- und Umwelttechnik e.V.).

Is it safe for humans?

It is definitely safe!

San:aer was specially developed for operation in the presence of people. Since the system does not emit UVC radiation directly to the outside and does not produce ozone, it can be used safely in busy rooms in continuous operation. Therefore, rooms can be disinfected continuously even in the presence of people.

San:aer is developed and produced in compliance with all safety measures and in full compliance with the European standards of consumer protection.For this reason, the device is very suitable for use in rooms where people are present whether public or private, at home or at work. 


Can people be in the vicinity while the device is switched on?

Yes, the design allows continuous operation even when people are present. During operation, people present are not exposed to UVC radiation and the system does not produce harmful ozone. At the same time, the san:aer unit is very quiet during operation.


Is UVC dangerous for people?

UVC radiation is basically very dangerous! It can cause irreparable damage to the skin and eyesight. Therefore, this radiation should only be used under controlled conditions and in compliance with all safety measures. UVC radiation sources should not be used by persons who are not aware of the associated dangers. The san:aer unit has a closed housing to protect it from the radiation. Furthermore complex light traps prevent UVC radiation from escaping.

What are the advantages of a UVC air sterilization device compared to HEPA filter devices?

Most widely used are 2 different technologies to purify air. Many devices use so called HEPA filters (High Efficiency Particulate Air filters) which are used to filter dust particles, pollen, smoke particles but also viruses from the air. However, only HEPA filters with HEPA 13 or HEPA14 classification can also be used to capture smaller particles. The systems can best be explained with a kind of “vacuum cleaner function” where the filter units have to be changed several times depending on the polluted room air and disposed of properly. The filters count as contaminated hazardous waste.

Devices using UVC radiation with a wavelength of 254nm, on the other hand, purify the air by destroying and killing the DNA of the viruses, bacteria or very fine aerosols contained therein by 99.9% through radiation energy without polluting the environment. There is no need for costly disposal of filters with devices such as san:aer that use this technology.


Where are the UVC air disinfection devices used?

Devices for air disinfection by means of UVC radiation sources are used practically everywhere where rooms need to be disinfected and hygienically cleaned. In the past, this technology was used mainly in hospitals, laboratories and industry. With the COVID-19 pandemic, UVC air disinfection units spread very quickly worldwide to many private and public areas of application in rooms (restaurants, stores, conference and treatment rooms, etc.) where people meet and spend time. The san:aer units make an important contribution to the efficient support of hygiene concepts and effectively reduce the spread of viruses and bacteria.

Where can I find more information about UVC air disinfection?
