Technical description Design duct air diffuser with discs has a diameter that is compatible with standard duct sizes. is equipped with aerodynamically designed discs that have a high induction capacity. The 60 mm dia. and 00 mm dia. duct air diffusers are equipped with Swegon s small discs. The standard duct diffuser is available in a number of sizes as shown in Figure as well as in the Dimensions and weights table. There is an aluminium profiled bracket along the top of the duct. The bracket runs longitudinally and serves as a flexible mounting bracket for hanging the duct diffuser from the ceiling. Materials and finish The duct air diffuser with discs is made of galvanized sheet steel and is painted in Swegon s white standard colour, RAL 900. The discs are made of recyclable ABS plastic. The air diffusers are also available in alternative standard colours: RAL 707 dusty grey, RAL 9006 white aluminium, RAL 900 jet black, RAL 9007 grey aluminium and RAL 900 signal white (NCS 000). Maintenance The air diffuser can be cleaned, if necessary, using lukewarm water with dishwashing detergent added or by vacuum cleaning using a brush nozzle. Environment The Declaration of Construction Materials is available from www.swegon.com.

One 90 bend. x Ød x Ød Two 90 bends in the same plane. x Ød x Ød Two 90 bends in aligment at right angles to one another. x Ød x Ød One damper. 6 x Ød x Ød One T-piece. x Ød x Ød Project planning The discs are rotatable through 60. This makes it possible to achieve an infinite number of horizontal or vertical air diffusion combinations without altering the airflow, sound level or pressure drop. The duct diffusers are well-suited for installation in the junction of a ceiling with a wall without reducing its flow capacity. The discs on the back side are then set for upward air discharge enabling the duct air diffuser to operate as a air diffuser with one-way air discharge. See Figures and for examples of principle air diffusion patterns. Normal hanger length is 00 mm. The smallest permitted hanger length is 00 mm which generates slightly increased throw. m = methodic error. Method for measurement of airflows in ventilation Installations.

Commissioning An C (see under accessories) or a flow measuring damper installed in the duct system upstream of the duct diffuser is recommended for commissioning and airflow measurements.

Installation Adjust the duct diffuser using the nuts (9) until the air diffusers are horizontal and have the correct height above the floor. Fit the white plastic covering supplied () onto the threaded rod. Phase A While the duct section () is lying on the floor, insert a size M-8 bolt () approx. 00 mm from the end on the longitudinal profiled bracket (). Do the same in the other end of the profiled bracket. Secure the bolts in the profiled bracket with long nuts (). Screw a threaded rod () of appropriate length into each long nut. Secure the Z-profiled brackets (6) with bolts to the ceiling to serve as mounting brackets for the duct-shaped air diffusers with discs. Hang the duct air diffuser with discs () in the Z-profiled brackets (6) and join it together with the connecting supply air duct (7) using the standard duct joint (8) included in the supply. Phase B Remove the end cover () and move it to the outmost section if more sections are to be installed. Press the distribution joint supplied (0) in the mounted section of the duct diffuser (). Insert the guide pin () in the free end of the installed section. Repeat phase A to install the next section (). Now it is sufficient to use one bolt in the other end when the second duct diffuser section is to be secured across the joint to the section that you ve already installed. Secure the distribution joint (0) with self-tapping screws in the sections. Repeat Phase B for last section. The duct diffuser is suspended by hangers from the ceiling. The air diffusers can be installed as in the following examples: B I.a. I. Position on delivery II. b, II. Position after reassembly and installation C Figure.

Note the use of supplied joints (8) and distribution joints (0) included in the supply. In all deliveries, the end cover () supplied is already fitted to the first section. The end cover is always moved to the last section (except when only 00 mm long ducts are installed), see Phase B in Figure.

Technical data Sound level db(a) applies to rooms with 0 m equivalent sound absorption area ( db room attenuation). Throw l 0. is measured for isothermal air discharge and applies to installation 00 mm from the ceiling. A max. permissible temperature below room temperature of 8 C is recommended for standard setting of the discs. The recommended highest permissible air velocity in the duct upstream of the air diffuser is - m/s. For calculating the air stream propagation, air velocities in the occupied zone, or sound levels in rooms with other dimensions, we refer to our ProAir Web and ProAc calculation programs at www.swegon.com.
