Swirl diffuser Description, Areas of application and Benefits Diffuser type DAL 359 is a highly inductive swirl diffuser with a round or square front plate and fitted air control blades of ABS. It is suitable for use in both closed and open ceiling systems and allows optimal adaptation of the air distribution system to the prevailing site conditions. The large number of air conducting elements, with optimized airflow and acoustic characteristics, makes this device visually attractive and effective in managing high cooling loads in low ceiling heights. Areas of application - Comfort zone - Clean...

Swirl diffuser rotating discharge one-side horizontal discharge The blades, designed as wing-shaped profiles, produce a favorable deflection of the vertically streaming air into the horizontal direction of the face plate. Rotating around the bearing center achieves a defined and reproducible reduction by 50% of the discharge free area. A greater penetration depth and flat, horizontal air distribution is achieved with the same discharge volume flow. Form-fitting bearings and grated components prevent any accidental or unallowable adjustment. two-side horizontal discharge By using vertically discharging...
