KBE extruded aluminum linear bar diffusers with rear blade meet architectural demands for a versatile supply and return air duct that blends with accents linear design concepts and it provides more comfort and more control on airflow direction in each grille section. Rear blades are individually adjustable.
LBD-R can be used on the supply or return positions of heating, cooling or ventilating system. Linear bar diffusers are made of high grade aluminum extrusions for maximum strength and corrosion resistance.
