Product Description
OTO Series curved slot swirl diffusers by EffectiV HVAC™ are designed to be used in air conditioning, ventilation and heating systems at a temperature differential up to 22ºF (12ºC). They can be mounted in false ceilings, on drywall, or suspended from the ceiling, from 8.5 feet to 13 feet (2.6 up to 4 meters) high. OTO diffusers allow a flow variation of 60% while keeping the air stream stable.
The particular design of OTO diffusers creates a uniform airflow along the length of each aperture. The radial configuration of the eight curved slots produces a rotational blade jet pattern. The resulting high velocity swirl diffusion combined with a Coanda effect results in efficient mixing of supplied air with room air, a high induction ratio and reduced air stratification.
As a result of the collaboration between Lievore, Altherr & Molina and MADEL®, OTO’s original design allows for manufacturing from a single continuous sheet, without any edges highlighting an assembled construction. This results in very smooth airflow characteristics while creating new design possibilities and reducing the visual impact within the architectural surroundings.
