Square diffuser with vanes in circular radial arrengement. With access by PUSH fasteners The AXO swirl diffusers are designed to be applied in air conditioning ventilation and heating systems . They can be mounted in false ceilings or suspended from ceiling. The design of their vanes and its radial arrangement in the diffuser cause a 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 individually adjustable vanes allow to change the supply angle to adjust the diffuser to the different architectonics environments. Their sectored vanes emit a uniform air flow all over the passage section. The AXO 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.
