3 Description Application The nozzle jet diffuser type DSA was developed especially to keep large windows free from condensation. Its high penetration depths, despite small air volumes, and its favourable acoustic behaviour allow it to be used for a wide range of different applications. The jet nozzle diffuser type DSA is suitable for installation in ceilings and floors. To achieve a flat surface, a cover plate, which conceals the nozzles, can be installed. The models with adjustable nozzles allow virtually unlimited settings, as the nozzles can be adjusted individually to the desired throw direction. The nozzle jet diffusers are available in one- or two-row versions. Construction Nozzles - Plastic, similar to RAL colour 9010 (white (-DW)) or RAL 9005 (black (-DS)) Faceplate - Sheet steel painted to RAL 9010 (white, -F9010) or RAL 9005 (black, -F9005) Model DSA-F with fixed nozzles, with faceplate riveted to the plenum box. DSA-V with manually individually adjustable nozzles, with faceplate riveted to the plenum box DSA-D with fixed nozzles, with dismountable faceplate. DSA-VD with manually individually adjustable nozzles, with dismountable faceplate. DSA-...-1/ one or two row version Accessories Cover plate (-AB) - painted sheet steel to the RAL colour of the face plate Plenum box (-AK) - Galvanised sheet steel, including a lateral connection pipe and attachment eyes. Rubber lip seal (-GD1) - at the plenum box connection spigot, made of special rubber Damper (-DK1) - in plenum box, adjustable at the front, made of galvanised sheet steel, for air volume regulation. Hit-and-miss damper (-SS) - galvanised sheet steel (only possible for DSA-D0-... and DSA-VD-...) Internal insulation (-Ii) - thermal insulation at the inside of the plenum box External insulation (-Ia) - thermal insulation at the outside of the plenum box Fastening Permanent connection (-FV) - faceplate riveted to the plenum box (standard for DSA-F0-... and DSA-V0-...) Screw mounting (-SM) - Standard for DSA-D0-... and DSA-VD-... with raised countersunk head tapping screws (on-site) Concealed mounting (-VM) - Pole brace fixing (possible for DSA-D0-... and DSA-VD-..., at an extra charge) only available with plenum box. Attention: Please note the adjustable nozzles may only be cleaned by wiping the nozzle with little pressure. The nozzle jet diffuser DSA can be used up to a room temperature of +50 C. 04/01-3
