weather protection grille or weather-proof louvers spezial shapes

WSG: Special shape

WSG weather-proof louvers act as an duct closure for mounting on the outside of a building or in ventilation openings on outside walls. The Grillair can also be fitted to machinery and equipment as uncontrolled air inlets or outlets or as protection grids. The specially formed blades prevent precipitation from entering. Splash water is drained through the drainage nozzles.

WSG-75: Heavy-duty designe, side cut

The design is based on a welded and highly stable profile frame with specially fitted blades. Two or more tie rods fixed through the construction are spaced at maximum 800 mm. The entire weather-proof grid is bolted together to form a compact and torsionally rigid unit. A spacer separates each blade from its neighbour and fixes it at the same time. At the rear is a protective grating with a mesh width of 16 mm to prevent the ingress of unwanted foreign bodies. Optionally, the WSG weather-proof louvre can be supplemented by an insect screen.
