Catalog excerpts

The swirl diffusers of OTO Series are designed to be used in air conditioning, ventilation and heatingsystems at a temperature differential up to 12 C.They can be mounted in false ceilings or suspended from the ceiling, from 2,6 up to 4 metres high.The OTO diffusers allow a flow variation of 60% keeping the air stream stable.The radial configuration of its eight sections produces a rotational induction of air with Coanda effect and the high airflow rate reduces stratification. The particular design of the vents creates a uniform airflow along the length of each aperture.As a result of the collaboration with Lievore, Altherr & Molina , the original design of the OTO diffusersallows manufacture from a continuous sheet, without any edges which highlight an assembled construction. This results in very smooth airflow characteristics, optimising its design function and reducing the visual impact within the architectural surroundings. > 1 09/04 size="-1">
