Description
Product Description
External weather louvres are externally mounted air transfer devices for fresh air and exhaust air of air conditioning systems. Installed in external walls and facades, their narrowly arranged blades give good protection against direct ingress of rain, leaves and birds.
Aerofoil Blade Design
Low differential pressure and low air-regenerated noise due to aerofoil blade profile — free area of approximately 60% (45% with insect screen).
AL & Galvanized Steel Options
WRL-AL (aluminium) and WRL-G (galvanized steel body and wings) — stainless steel also available as option.
Modular Multi-Section
Large areas achieved by arranging multiple single sections horizontally and/or vertically — subdivided construction for custom dimensions.
Rain & Bird Protection
Narrowly arranged blades prevent direct rain ingress, leaves and bird entry while maintaining adequate free area for airflow.
Simple Installation
Perimeter border for simple and quick installation. Sections can be combined into continuous horizontal runs.
High Corrosion Resistance
Electrostatic powder painting RAL 9010 standard with high corrosion resistance. Any RAL colour available. SS option for aggressive environments.
