La description

Dasco Linear Slot Diffusers for both supply and return applications DLD-C(S/R) are designed to give unobstrusive continuous air diffusion with a pleasing aesthetic appearance . Hairline joints ensure clean continuous runs of linear slot diffusers for both active and dummy sections. They are normally connected to the main ducting system by means of connection boxes (Plenums), and are adjustable in height for accurate lining-up with the ceiling.In general , DLD-C(S/R) linear slot diffuser is considered as a unique type of an air distribution device, dispenses proper air quantities, controls air pattern for ultimate human comfort and adapts to any design concept perceived by architect / design engineer. Dasco linear slot diffusers DLD-C(S/R) are designed to give a comprehensive and full range of air flow patterns and volumes. Their deflector blades and volume control dampers give a full flexibility in air patternand volume control. These are fully adjustable from the face of the diffuser. Single or multiple slot arrangements can provide any combinations of horizontal, vertical or any intermediate setting of air flow pattern over a full range of **0º adjustment, as each slot is individually adjustable. Volume control dampers consist of two strips of extruded aluminum profiles, one fixed and one movable. They can be also usedas equalizing grids.High quality and heavy gauge extruded aluminium profiles. They are available in white polyester powder coated finish. However, any other RAL standard colours are also available upon customer’s request. Deflector blades and dampers are also made from extruded aluminum profiles.
