The
door grilles (Non-Vision / Partition) are flush
mounted air terminal devices used for air movement between two conditioned
spaces while preventing vision. They are constructed as inverted V shape blades
assembled one above the other, with fixed
spacing to a frame called the fixed
frame. Fixed frame is installed on one side of the partition, while a sliding
frame is fixed
on the other side. Sliding frame enables the use of a door grille to suit different
partition thickness.
