Sound attenuator splitter lindab | acoustic solutions TUNE-A Dimensions TUNE-A A A b* Description TUNE-A is the basic element in the TUNE attenuator series. TUNE-A is manufactured with a frame of galvanized sheet and stone wool absorption material covered with glass fleece surface. The TUNE-A is available in width 100, 150 and 200 mm. The TUNE-A is also available in other lengths than shown in the tables. Special materials and sizes, please contact to Lindab sales. Tools for dimensioning and planing NOTE that dimensioning your attenuator is a delicate bal- ance between numbers of splitters (n) and air pressure in duct. More splitters give a higher attenuation, but also a higher pressure in duct. A higher pressure will result in a higher energy consumption to make system run. See how to find the numbers of splitters (n) in duct and how to calculate (S) from a given (a) in the seperate AeroDim SLRA-SLRS installation instruction. You can also choose to use Lindab's IT-program lindQST or DIMsilencer where splitter distance (S), width (B) and height (b) can be optimized for best preformance. Consult your local Lindab dealer for further information. B Max. 1200 l b* = Manufactured height of splitter is b-5 mm, to fit into duct.

Length of splitter should be 50 mm shorter than length of duct. Due to the symmetrical construction of the TUNE-A, no spe- cial concerns are needed when installing the splitter. Even the airflow direction can later be changed without having to turn the splitter around. We reserve the right to make changes without prior notice 1 2019-02-26
