Una maggiore <strong>di</strong>stanzafra le <strong>alette</strong> comporta una c<strong>ad</strong>uta del flusso d’<strong>aria</strong>, una zona orizzontalepiù ristretta, una m<strong>in</strong>ore per<strong>di</strong>ta <strong>di</strong> carico ed una <strong>di</strong>m<strong>in</strong>uzionedel livello <strong>di</strong> pressione sonora.Per velocità f<strong>in</strong>ale massima dell’<strong>aria</strong> <strong>di</strong> 0,5 e 0,75 m/s, è necessariomoltiplicare il valore L per i coefficienti correttivi 0,63 e 0,42 rispettivamente.Per <strong>in</strong>stallazione a parete il lancio si riduce del 10% perogni 40 cm <strong>di</strong> <strong>di</strong>stanza dal soffitto, f<strong>in</strong>o <strong>ad</strong> un valore massimo <strong>di</strong>riduzione del 30%.TECHNICAL DATA: the follow<strong>in</strong>g tables and <strong>di</strong>agrams refer tomount<strong>in</strong>g flush with the ceil<strong>in</strong>g and with an open<strong>in</strong>g of 3 mmbetween the first vane and the <strong>di</strong>ffuser frame. A greater <strong>di</strong>stancebetween the vanes means a drop <strong>in</strong> air flow, a more limited horizontalarea, less pressure drop and a reduction <strong>in</strong> sound pressurelevels.For f<strong>in</strong>al maximum air velocities of 0.5 and 0.75 m/s, it is necessaryto multiply the L value by the correction factors 0.63 and 0.42respectively.For wall mount<strong>in</strong>g the throw is reduced by 10% for every 40 cm<strong>di</strong>stance from the ceil<strong>in</strong>g, up to a max reduction value of 30%.DR / I / 10.99 / I-UKCI RISERVIAMO MODIFICHE DI COSTRUZIONESENZA PREAVVISOSUBJECT TO CHANGES WITHOUT NOTICE8SISTEMA QUALITÀUNI EN ISO 9001QUALITY SYSTEMOFFICINE VOLTA S.P.A.
