lindab | we simplify construction Versio - Ceiling diffusers RS14 Technical data Following RS14-V+plenum box data are valid for MBB-S/-E. For MBC and MBE data, go to www.lindQST.com Capacity Air flow q v [l/s] and [m 3 /h], total pressure Δ p t [Pa], throw l 0.2 [m] and sound power level L WA [dB(A)] can be seen in the diagrams. Frequency-related sound power level The sound power level in the frequency band is defined as L WA +K ok . K ok values are specified in charts beneath the dia- grams on the following pages.
