lindab | we simplify construction Nozzle diffuser DCS Technical data Capacity Volume 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 effect level The sound effect level in the frequency band is defined as L WA + K ok K ok values are given in charts beneath the diagrams on the following pages.
