The KOOLAIR‘s DF-LIT-E-4.0 is a slot diffuser for air supply and return, with slots (15, 20, 33, 40, 50 mm). Complete with movable blade for horizontal and vertical supply. It is designed to be installed in suspended drywall ceilings or suspended panels, and is distinguished as it is an invisible linear diffuser with a pleasing aesthetic appearance.
The absence of visible profiles means it is aesthetically pleasing, as it is practically imperceptible. We offer the option of manufacturing with different slot widths depending on the required supply or return air flow rate per linear metre. It is also suitable for flush installation. It is manufactured from extruded aluminium profiles, and comes with a standard RAL-9005 finish.
