Camfil’s CamVane weather louvres successfully prevent moisture ingress into Copenhagen Airport’s ventilation system

Copenhagen Airport and Camfil have been working together for years to ensure better and more reliable air filtration and enhanced protection against harmful particles and gases in the airport’s indoor spaces. However, the airport identified a problem with a particular air handling unit (AHU) that was exposed directly to the weather, allowing moisture to enter the system. To address the issue, Camfil proposed its CamVane weather louvres, designed to remove water droplets and moisture from the incoming airstream, thereby protecting the ventilation system and the air handling unit.

The long-standing partnership between Camfil and the airport in the Danish capital is built around a shared commitment to providing clean air through ventilation systems and the air filters used in them. When a moisture ingress problem was identified in a specific ventilation system, the airport’s technical team turned to Camfil for a solution.

“The system is located directly next to the Øresund Strait, which separates the Danish island of Zealand from the southern Swedish province of Skåne. Two of the air intakes are installed relatively close to ground level and face east. This particular location exposes the system to rain, strong crosswinds and saltwater spray from the sea. As a result, moisture enters the ventilation system, wetting both the filters and the equipment itself,” representatives of Camfil Bulgaria explained.

The repeated wetting of the filters necessitates more frequent replacement, while saltwater causes corrosion and damages the system’s base plate. This results in additional equipment and maintenance costs.

The solution to the moisture ingress problem is Camfil’s CamVane weather louvre, developed to protect ventilation systems and air ducts against adverse weather conditions. Installed at the air intake, CamVane is designed to capture water droplets carried by the incoming airstream and drain them away from the system.
