TROX WGF External Weather Louvre Instructions

WGF

SPECIFICALLY FOR FAÇADE INSTALLATION

External weather louvres – specifically for façade installation – as a protection of air conditioning systems against the direct ingress of rain, leaves and birds into fresh air and exhaust air openings.

Maximum width of 2000 mm, maximum height of 2500 mm per section
For installation into façades or for the construction of enclosures for machinery or electrical equipment
Low differential pressure due to aerofoil blades
Low air-regenerated noise
All aerodynamic data is measured in aerodynamics and acoustics
laboratories
Variants made of galvanised sheet steel or aluminium
Flexible arrangement of sections for covering large areas (should to be fixed on the support structure provided by others)

Optional equipment and accessories Corner section

Insect screen
Powder-coated or with anodised finish

General Information

Application
