Door Grilles are fitted on doors and wall portions where sight/vision blockage is necessary. DG’s are also known as Privacy Grilles or Non Vision Grilles.  Their use allows the air to move and to evenly balance the existing various pressure levels between multiple treated spaces. It can be used as Transfer Air Grille (TAG) for wall and partition openings and its architectural finish is eye catching. Blades and frame are constructed from extruded aluminium alloy profiles and powder coated to standard white color.
