The city air cleaner
The efficient solution for improving
air quality in urban environments
The required characteristics define the system – and not vice versa.
The device actively sucks in the outside air and removes pollutants from it, both fine dust particles of categories PM10 and PM2.5 as well as gaseous substances such as nitrogen oxides. The cleaned air is released into the environment.
The combination of patent-pending innovations and proven technologies makes a pragmatic solution for better air in cities possible until the causes of air pollution are eliminated. The system will offer an ideal cost-benefit ratio: as much air cleaning performance as necessary at as little cost and effort as possible.

The functional principle
The closed system absorbs air actively along side the roads where the noxious substances accumulate.
The device extensions, weight and operation are optimally constructed for easiest handling and uncomplicated change of location.
The flow of cleaned air decelerates and is released towards the footpath.The air suction system with its motors made to specification is operated by energy stores which are powered by solar cells mounted on the top of the air cleaner device.
Should higher energy supply be needed e.g. during rush-hour additional power can be supplied by an integrated fuel cell or by an external power supply.
The intelligent control system guarantees optimal energy efficiency as air cleaning is only activated when air pollution surpasses the specified level.
Special developed filter unit
The heart of the city air cleaner are the synchronous cleaning units with a double retention system (preliminary filter, pocket filter F7 and activated carbon filter). They ensure that 85% of the solid components in the air absorbed such as nitrogen oxides can be retained.
Specially developed motors are used for this purpose.
The functional mesh 5plus dust evo forte from trittec AG is a professional solution for permanent protection against insects, pollen and fine dust. The ultra-fine, unique fabric consists of a bicomponent material and creates the highest light and air flow with a highly transparent view. The particle protection fabric has been independently tested and certified as allergy-friendly.
Monitoring air quality in urban environments
Gathering professional data on air quality in cities is a costly and timeconsuming activity. We offer such data free of cost as our air cleaners gather this data on a real-time basis.
The sensors diagnose problems such as traffic jams or high air pollution levels on a real-time basis so that counter measures such as redirecting traffic flows or increasing the performance of air cleaning units can be implemented immediately.
The right solution for
The high-performance model S will currently cleanse up to 60.000 cubic meters of air per hour, the equivalent volume of 1.800 standard container.
The external energy supply enables an extremely compact design and increases the cleansing capacity of this model. The required energy can be supplied easily by using adapter from surrounding energy sources e.g. street lighting or electric charging stations for vehicles.
Stationary use, is transported and set up with a truck.
Our compact model M is designed for indoor applications. Due to the compact dimensions of the air filter systems, they can be individually designed and adapted to the respective environment: Whether for almost invisible use in hotels or corporate headquarters, or as an advertising medium in public spaces, up to the luxury version for integration into living spaces. And that particularly quietly.
Three model variants are planned for series production of the mono-units. The top model achieves an air cleaning capacity of up to 30.000 m3/h.

Frequently Asked Questions
How does the city air cleaner work?
Where does a city air cleaner make sense?
In short: Wherever the air is polluted with excessive concentrations of pollutants, worldwide. This can be on busy roads and squares, in regions with smog pollution, on construction sites and other places where a lot of dust is generated. The city air purifier can help companies, retailers and organizations, property developers, hotels and restaurants with outdoor areas, airports and supermarket car parks, wherever the air pollution is too high.
Are connections and other preparations necessary?
Dimensions, weight and mode of operation are optimized for easy relocation and handling - no foundation required. Model E of the urban air purifier is fully self-sufficient and does not require any connections, Model S is supplied with additional energy by an external power supply. In any case, the city air purifier is ready for operation within a short time.
What noise is to be expected?
The city air purifier is low-noise, even in full operating mode it is no louder than the background noise of a busy café. As a rule, traffic noise will predominate anyway, because the city air purifier only becomes active when the pollution in the ambient air requires it - as in rush hour, for example.
How strong are the air flows at the urban air cleaner?
The suction airflow is about as powerful as that of a larger vacuum cleaner, strong enough for effective efficiency, but moderate enough not to restrict road traffic or pedestrians. The purified air is distributed and slowed down before it gently flows out at the top of the city air purifier.
Where can I experience a city air cleaner in operation?
Come and visit us in Trittau in the south of Schleswig-Holstein and experience the city air purifier in action. We would be pleased to inform you about the current status of further installations. You can simply contact us by mail.
What does a city air cleaner cost?
During the development of the device, economic efficiency in relation to performance was the top priority. Depending on the model, configuration, extras and last but not least the desired quantity, we can make you an attractive, individual offer. Our sales team is looking forward to making you a proposal: email@example.com
What does the brand name "Purevento" mean?
Our brand name "Purevento" is composed of the terms "Pure" for "pure" and "vento" for "wind". This combination of words illustrates the air-purifying effect of a fresh breeze that helps reduce the concentration of air pollutants - just like Purevento's urban air cleaner.
Should air pollution not be avoided instead of cleaning air afterwards?
Of course, this must be the primary objective of all efforts to achieve clean air. However, this is a long way off: as long as cars are powered by combustion engines, the air is polluted with solid and gaseous pollutants. Even purely electric road traffic would still produce fine dust due to tyre and brake abrasion. Therefore, an interim solution for better air quality makes sense in many places. The urban air purifier sees itself as a bridging technology that provides relief until the causes of air pollution have been eliminated in the long term.
