Air Jet Dispersal Throw l x [m] at an average speed of 0.2, 0. and 0. m/s, 0 blade setting without ceiling effect (distance from grille to ceiling over 800 mm) can be seen in the diagrams. Correction for dispersal - see table below. Sound power level WA Sound power level WA [db(a)] at 0 blade setting can be seen in the diagrams. The sound power levels apply for grilles without a opposed blade damper. See the table below for correction of sound power level on blade settings [db]. Frequency-related sound power level The sound power level in the frequency band is defined as Wf = WA +K ok. K ok values are given in the table below.
