The RXO swirl diffusers are designed to be applied in air conditioning ventilation and heating systems. They can be mounted in false ceilings or suspended from the ceiling. The design of their vanes and its radial arrangement in the diffuser cause swirl air supply with a coanda effect, which provides a high level of induction rate of the air in the atmosphere and reducing the stratification. Their sectored vanes emit a uniform air flow all over the passage section. The RXO series diffusers admit a flow variation of 60% keeping the air stream stable. These diffusers can be used from 2,6 up to 4 meters high and at a temperature differential up to 12ºC.
