PDD-10R-A (Personal Displacement Diffuser) is an adjustable constant volume air terminal for use in raised floor air systems. It features 20 gauge (1mm) galvanized steel construction, pre-painted flat black. To facilitate air flow, one side of the terminal includes a 13.2″ x 4.8″ (335mm x 121mm) opening to the plenum.

The nominal 10″ (254mm) diameter cast aluminum grille produces omni-directional displacement air flow. A manually adjustable sliding damper allows space occupants to limit air flow. Ten (10) standard grille colors are available; custom colors and finishes can be provided to match architectural design (specify on order).
