Modern airports are called airport cities nowadays. The term covers the change in perception of airports. They are representative infrastructure properties with a multifaceted range of services that goes beyond actual flying. An airport is the gateway to the world, but also a location for several other visitors who do not enter an aircraft while there. The indoor air quality (IAQ) and indoor air hygiene pose great challenges to the operator regarding quality and costs. The ventilation of the properties with outdoor air is very demanding especially for an airport, since the outdoor air is loaded with kerosene and its levels fluctuate with time. This pollutant that can be sensed even in the minutest volumes should not reach inside the building. Ionair removes kerosene very efficiently and in a robust manner (even with high humidity or considerable fluctuations). In addition, even the pollutants generated from other sources inside the building have to be minimized. Smoker lounges, toilets, restaurants and the material transport, such as, for example, baggage return conveyor belts, generate pollution of the indoor air continuously.

ionair helps the operator from the planning up to decades of operation to achieve the best possible quality of air at low investment and operational costs. This is measured across the total cost of ownership (TCO). The changed building uses lead to necessary adaptations time and again even in the operation. With ionair, this can be done quite easily without intervention in the infrastructure.

ionair inactivates virus over 99%

The Air Quality System (AQS) of ionair in the supply air frees the indoor air from airborne surrogate viruses (non-pathogenic covered Phi6 bacteriophages with structure, particle size and environmental stability equivalent to that of SARS-CoV-2). This has been certified by the Fraunhofer Institute for Building Physics IBP. This is very positive news for the Swiss Company and our international customers.
