Door Transfer/Non Vision Grille

The Advanced Air Model Series 51DG Door Transfer/Non-Vision Grilles are designed to meet the demand for top quality andcompetitive prices.

The grilles are carefully constructed to be unobtrusive in appearance for architectural excellence. Model Series 51DG offers the largest free area possible (average > 50%) with a completely sight-proof design, utilising an inverted 'V' shaped louvre on 20mm centres. Widely used, not only in doors and partitions, but also in place of conventional exhaust and return grilles where it is important that the interior of the plenum or duct be concealed. The inverted-V blades not only block vision, but also provide strength. When mounted in the lower portion of a door, a door grille is naturally subjected to bumps and kicks.

The 51DG durability assures good looks and long service. Screw holes in the frame are countersunk for smooth appearance after installation.
