WG

External weather louvres for the protection of ventilation and air conditioning systems

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

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.

Nominal sizes	200 × 165 – 2400 × 1650 / 1600 × 2310 mm
Width subdivided	up to 4900 mm
Height subdivide	up to 4720 mm
