Diffusori ad effetto elicoidale

Dralldiffusor Typ RA

I diffusori serie RA sono elementi di aria di mandata con pale disposte tangenzialmente per diffondere il flusso d'aria. Sono indicati per il montaggio all'interno di controsoffitti. Le eccellenti proprietà di erogazione restano inalterate se usati come elementi per una diretta mandata dell'aria in ambiente. L'elevato tasso di induzione di aria secondaria rende i diffusori a effetto elicoidale indicati anche per sistemi che immettono aria con una portata variabile (dal 25 al 100%) e in zone di assemblaggio, dove è richiesto un grado elevato di comfort.
