FIXED CONES CIRCULAR DIFFUSERS TECHNICAL CHARACTERISTICS OVERVIEW: The KU4 series diffusers are designed for application of air conditioning, heating, and ventilation. These diffusers are made from a series of fixed cones and are used both in the supply and extraction of air. This diffuser is equipped with an air tight gasket on the back. The standard installation height of the diffuser is between 2,6 and 4,1 meters. MATERIALS : the KU4 series diffusers are made from extruded aluminium. The surface finish foreseen an epoxy powder paint finish in silver RAL 9006 or white RAL 9003. INSTALLATION : The diffuser is fixed by means of two screws to the fixing bridge or directly to the plenum or ceiling. The diffuser is supplied complete with the two screws and the fixing bridge. BUTTERFLY DAMPER : The KU4 series diffusers are supplied complete with a butterfly regulation damper. The damper is made in black PVC and is easily adjustable through the diffuser. CONNECTION PIECE : The KU4 series diffusers can be supplied with connection piece KU 44 for connecting to the flexible duct. The KU 44 connection pieces have base supports and a fixing bridge for the diffuser. INSTALLATION METHOD Using the diagram shown below, it is possible to make a first general selection of the diffuser on the basis of the air flow. It is advised in any case to check, using the diagrams of the technical data shown in the following pages, the effective compliance of the choice made and the specific intended uses of the diffuser. DESCRIPTION FOR TENDER : circular fixed cones aluminium diffuser painted RAL 9006 or RAL 9003 complete with regulation damper, fixing bridge and tightening screws; removable central part to allow for a correct installation. nominal neck diameter mm

ADJUSTABLE CONES CIRCULAR DIFFUSERS OVERVIEW OVERVIEW: The KU5 KU6 series of diffusers are composed from an external containment cone and by a central adjustable section with cones that may be adjusted individually to the nearest millimetre. The different positioning of the round elements allows to vary the direction of the air to obtain combined or single are flows, both vertically or horizontally. For this reason, this supply air diffuser is ideal in all those applications where it is necessary to heat or cool. In the same way it can be used for the extraction of air from the room. The standard...

ADJUSTABLE CONES CIRCULAR DIFFUSERS MATERIALS DESCRIPTION FOR TENDER: KU5: aluminium circular diffuser painted RAL9010 for use in ceilings, with manually adjustable cones to optimize the direction of the air flow; milimetric regulation central screw in galvanized steel; predisposed for connection to a plenum or a flexible duct; available as standard model or complete with aluminium panel painted RAL9010 for fitting into modular ceilings; sup pliable with a galvanized steel butterfly regulation damper, adjustable through the cavity obtained in the central regulation screw.

ADJUSTABLE CONES CIRCULAR DIFFUSERS VERSION WITH AUTOMATIC REGULATION WITH THERMOSTATIC SPRING The KU5 CT diffusers allow to automatically regulate the cones in the summer or winter position without the need of a technician. The work without any auxiliary power (e.g.. electrical power supply) and do not require any maintenance. The movement of the intermediate cones is controlled by means of a special shape remembering spring who's cycle of use determines the position of the cones in relations to the temperature. In this way the flow of air is controlled in relation to the temperature, enabling...
