Operating Data
Data refers to 1 m long diffusers, with a terminal velocity Vt = 0.25 m/s, flush-mounted on the ceiling and with horizontal air throw (Coanda effect). Values refer to the diffuser without damper or with sliding damper fully open. Values refer to the diffuser with deflectors set in operating position, with 50% free area reduction. The deflector position reduces the effective area. With deflectors fully open, or when the diffuser is used for return air, the airflow rates (m³/h) shown in the table may vary.
- Vk: effective speed (m/s).
- m³/h: flow rate.
- Pa: pressure drops in Pascal.
- L(m): air throw in metres calculated on ceiling installation, terminal velocity 0.25 m/s.
- dB(A): noise level.

Elemento estetico di raccordo tra i due linee di diffusori lineari con angolo di 90° e lunghezza 500 mm per lato. Non ha funzionalità di ventilazione. Il kit di continuità è un accessorio necessario per poter realizzare linee in continuità di diffusori lineari di lunghezza superiore ai 2 metri. E’ costituito da due piastrine di giunzione che permettono l'allineamento ed il collegamento di due componenti della linea.Angolo di collegamento Kit di continuità 
Air Throw Characteristics
L’immagine illustra un esempio delle diverse configurazioni di lancio possibili di un diffusore lineare a feritoia, ottenibili mediante la regolazione dei deflettori interni: lancio orizzontale monodirezionale, lancio verticale e lancio inclinato/divergente. La possibilità di orientare il flusso d’aria consente di adattare la diffusione alle diverse esigenze impiantistiche e ambientali.Esempi di Configurazioni di Lancio dell’Aria
