External weather louvres, (38 mm blade pitch)
Ideal for use on the external walls of a building for intake or extract air, the 45 deg blades are fixed at 38mm centres and have excellent integral rain defence features.
Constructed from extruded aluminium sections, frames are fully welded and fitted with a bird guard as standard. Standard finish is mill aluminum, with other colours available on request if you can supply the RAL number.. Free area approx 50%.
Includes a bird mesh on the backside.
These do not have a spigot and have to be used in combination with the Plastic Grille Boxes if connecting to flexible ducting, spiral ducting is often just butted against it.
The size shown in the image is a large grille.
