Function
Air is supplied or extracted through the horisontal blades. The design of the grille prevents rainwater from reaching the ductwork. The slot between the frame and the top blade is sealed, thus preventing rainwater from entering the ductwork from above. Drops of water are collected in the grooves at the front edge of the blades. Water flows to the side grooves, where it drops down.
Blade construction
Depth of blade 65 mm, distance between blades 50 mm, free area 50%
