Supply and return air systems can be used in comfort rooms, such as offices for cooling up to Δt= – 10K. Mounting height 2.6 – 4m.

Manually adjustable air deflection blades in the supply air allow a horizontal or vertical air jet guidance. Adjusting the blades does not change the free cross-section, i.e. pressure loss and loudness are the same in all blade positions. The exhaust diffuser is provided with a black perforated sheet instead of air deflection blades.
