Élan-04R-180 (Personal Comfort Diffuser) is an adjustable constant volume air terminal for use in raised floor air systems. It features an 18 gauge (1.3mm) galvanized steel collar, pre-painted flat black.
The nominal 4″ (102mm) diameter cast aluminum grille is directionally adjustable, and produces substantially horizontal displacement air flow. An optional 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).
