A GOOD-QUALITY AIR FOR THE MOBILITY REVOLUTION

Clean Air for Clean Energy

Charging stations equipped with an effective intake air system offer operators a significant advantage: more vehicles can be charged at a station within the same timeframe, increasing revenue. However, there is a certain risk associated with cooling charging stations using air. Air can contain fine dust and organic materials such as rust, tire debris, soil particles, pollen, leaves, and tiny insect parts, which can get inside the charging station. These can damage the sensitive electronic components if they are allowed to accumulate on them. If moisture penetrates the charging station, components can also corrode, causing short circuits.

Filter Panels for Air Quality

Filter panels are mentioned as a solution to maintain safe air intake, likely by reducing particulate matter and pollutants that could be generated or concentrated near these high-traffic areas.

Innovation and Safety

To protect the electronic components and optimize the availability of the charging stations, Airwatec together with Freudenberg Filtration Technologies has developed special filter panels, some using the P15/500 S filter medium. A high-performance nonwoven (Filter Class ISO Coarse 75%) is welded into the frame to provide a dustproof seal and ensure stability, as well as reliable protection from dust, dirt particles, and water droplets. When using these filters, charging stations can achieve a protection class of IP 54. The filter medium’s progressive structure and high dust holding capacity result in an exceptionally long service life.

Customizable for Universal Application

The filter panels are designed to allow flexible adaptation to the dimensions of the ventilation space. The filter element is extremely stable and requires only minimal mounting to be installed in the charging station. In most cases, a slide-in rail or clamps are all that is required to fasten it in place. Maintenance is also simple and requires no expert knowledge. These factors also make it easy to change the filter and reduce maintenance costs. To achieve reliable operation for the charging stations, the filter panels should be changed once or twice a year—depending on the ambient air quality. On roads subject to heavy traffic or in rural areas, it is sensible to change the filter towards the end of the pollen season.

The new filter elements provide the perfect protection for sensitive electronic components and minimize the risk of downtime.
