External Louvres | Type WGK

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.

Key Features

• Maximum width of 1997 mm, maximum height of 1997 mm
• 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

Optional equipment and accessories

• Installation subframe
• Insect screen
• Powder-coated or anodised

Application

• External weather louvres of Type WGK, with small blade pitch, 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

• 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: 97, 147, 197, 297, 397, 497, 597, 797, 997, 1197, 1397, 1597, 1797, 1997 mm (intermediate sizes: 98 – 1996 mm, in increments of 1 mm)
• H: 97,147, 197, 247, 297, 347, 397, 447, 497, 597, 797, 997, 1197, 1397, 1597, 1797, 1997 mm (intermediate sizes: 122 – 1972 mm, in increments of 25 mm

Materials and surfaces

• Border, blades and stabilising mullions made of extruded aluminium sections, material no. EN AW-6060 T66, anodised to EURAS standard, E6-C-0, natural colour
• Wire mesh made of galvanised steel
• P1: Powder-coated, RAL CLASSIC colour
• PS: Powder-coated, NCS or DB colour

Maintenance

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