WG

 External weather louvres to protect ventilation and air conditioning systems against the direct ingress of rain, leaves and birds into fresh air and exhaust air openings. In combination with insect screens, they also provide protection against insects. They are used for a wide variety of applications with regard to air flow and can also cover large installation openings. For single grilles, the following applies:

  • Maximum width of 2400 mm, maximum height of 2310 mm, maximum area of 4 m² (aluminium variant also as continuous horizontal runs)
  • Low differential pressure due to aerofoil blades
  • Low air-regenerated noise due to a rounded drip edge
  • Simple and quick installation due to perimeter border
  • Variants made of galvanised sheet steel, aluminium or stainless steel
  • Large-area arrangement of several single grilles in combination with support structure provided by others possible to cover very large installation openings  

 


Optional equipment and accessories

  • Installation subframe
  • Can be combined with multileaf or non-return dampers
  • Insect screen
  • Powder-coated or with anodised finish
