A diffuser is designed to control the characteristics of a fluid at the entrance to a thermodynamic open system. Diffusers are used to slow the fluid's velocity and to enhance its mixing into the surrounding fluid. A grille is an opening of several slits side by side in a wall or metal sheet or other barrier, usually to let air or water enter and/or leave but keep larger objects including people and animals in or out. Our ceiling diffuser is constructed from aluminum or plastic and finished in powder-coat white. Our fitting is manufactured from galvanized sheet metal and painted matt black inside. Our fitting is ideal for ceiling diffusers or air grilles.
