High Induction Adjustable Round Swirl Diffuser


AXO-C High Induction Adjustable Vanes Round Swirl Diffuser is available in 25″ (625mm diameter). AXO diffusers can be adjusted to supply swirl, 1-way, 2-way and vertical throw patterns. AXO can supply high air flow at relatively low sound power and has a high tolerance-to-air flow variation and duct angle.

Product Description

AXO swirl diffusers by EffectiV HVAC and MADEL® are designed to be applied in air conditioning, ventilation and 1 1/10 heating systems. The design of their vanes and radial arrangement supplies the air in a swirl pattern while leveraging the coanda effect. The resulting high induction ratio helps reduce stratification.


Their individually adjustable vanes support multiple angles to adapt the airflow to virtually any environment. Their sectored vanes, combined with a PERFAIR high-performance plenum mixing box, emit a uniform airflow all over the passage section.


The AXO series diffusers admit a flow variation of 60% while keeping the air stream stable. For optimal conditions, AXO diffusers may be used in ceilings 8.5 up to 13 feet (2.6 up to 4 meters) high and at a temperature differential up to 54ºF (12ºC).


The air pattern adjustability, high level of induction rate and reduced air stratification allow for designs with a much higher level of comfort and provides opportunities for significant energy savings.



The face and plenum box are ordered separately and attached together with a screw through the face fixed in the plenum crossbar.


AXO-C circular diffuser is available in 24.5″ (625mm) diameter.
