SPECIFICALLY FOR FAÇADE INSTALLATION

External weather louvres – specifically for façade installation – as a protection of air conditioning systems against the direct ingress of rain, leaves and birds into fresh air and exhaust air openings.


  • Maximum width of 2000 mm, maximum height of 2500 mm per section
  • For installation into façades or for the construction of enclosures for machinery or electrical equipment
  • Low differential pressure due to aerofoil blades
  • Low air-regenerated noise
  • All aerodynamic data is measured in aerodynamics and acoustics laboratories
  • Variants made of galvanised sheet steel or aluminium
  • Flexible arrangement of sections for covering large areas (should to be fixed on the support structure provided by others)

  


Optional equipment and accessories

External weather louvres are externally mounted air transfer devices for the fresh air and exhaust air of air conditioning systems. They are installed in external walls and façades. Their narrowly arranged blades give good protection against the direct ingress of rain as well as against leaves and birds. Under certain unfavourable conditions, such as heavy rain, and depending on the airflow velocity, slight quantities of water could enter with the air. This is why the airflow velocity in fresh air openings should not exceed 2 – 2.5 m/s.
