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
it might happen that slight quantities of water enter together with the air. This is why the airflow velocity in fresh air openings should not exceed 2 – 2.5 m/s.

External weather louvres as a protection of air conditioning systems against the direct ingress of rain, leaves and birds into fresh air and exhaust air openings

Key Features

• Maximum width of 2400 mm, maximum height of 2310 mm, maximum area of 4 m² (aluminium variant also for continuous horizontal runs)
• Low differential pressure due to aerofoil blades
• Low air-regenerated noise
• All aerodynamic data is measured in aerodynamics and acoustics laboratories
• Available in standard sizes and many intermediate sizes
• Simple and quick installation due to perimeter border
• Variants made of galvanised sheet steel, aluminium or stainless steel
• Flexible arrangement of sections for covering large areas (should then be fixed on a support structure which is to be provided by others)

Optional equipment and accessories

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

Application

• External weather louvres of Type WG for the fresh air and exhaust air openings of air conditioning systems
• Protection against the direct ingress of rain as well as against leaves and birds
• Recommended face velocity for fresh air openings: 2 – 2.5 m/s max.

Special characteristics

• Large areas can be provided by arranging multiple single sections horizontally and/or vertically (subdivided construction); single sections made of aluminium can also be combined into continuous horizontal runs
• Low differential pressure and low air- regenerated noise due to aerofoil blades
• Simple and quick installation due to perimeter border
• Free area of approx. 60 %, with insect screen approx. 45 %
• Silicone free

Nominal sizes

• B: 200, 400, 600, 800, 1000, 1200, 1400, 1600, 1800, 2000, 2200, 2400 mm (intermediate sizes: 201 – 2399 mm, in increments of 1 mm)
• Width subdivided max. = 4900 mm (intermediate sizes: 2401 – 4899 mm, in increments of 1 mm)
• H: 165, 330, 495, 660, 825, 990, 1155, 1320, 1485, 1650, 1815, 1980, 2145, 2310 mm (intermediate sizes: 166 – 2309 mm, in increments of 1 mm)
• Height subdivided max. = 4720 mm (intermediate sizes: 2311 – 4719 mm, in increments of 1 mm)
• Any combination of B × H

Materials and surfaces

• Border, mullion and blades made of formed galvanised sheet steel, aluminium or stainless steel
• Wire mesh made of galvanised steel or stainless steel
• P1: Powder-coated, RAL CLASSIC colour or PS: Powder-coated, NCS or DB colour

Maintenance

• Maintenance-free as construction and materials are not subject to wear
