Grilles L13 and L17 are linear, light type grilles, with fixed blades parallel to the 1^st dimension. They are made of anodized aluminum so that they have a high anti-corrosion protection and the texture of the grille surface does not change over time. They are suitable for wall, ceiling or air duct installation for air supply and exhaust.

Types L13.G1 and L17.G1 have fixed blades parallel to the 1^st dimension and 1 row of independent, manually adjustable blades, parallel to the 1^st dimension, internally to adjust the opening of the air stream. On request they can be manufactured with a small visible frame or a hidden type without a visible frame.
