High Induction Adjustable Aluminum Round Swirl Diffuser


AXO-ALU Aluminum Round Swirl Diffusers are available with black or white diffusion vanes, and in 12″, 16″, 20″, 25″ and 32″ face diameters.

AXO high induction swirl diffusers greatly help improve comfort and energy efficiency in commercial buildings when compared to standard diffusers. AXO series can supply high volume of air at relatively low sound power and has a high tolerance to air flow variation and the angle of the duct when entering the diffuser. They offer a very reliable performance and are ideal for VAV applications.

AXO-ALU diffusers are ideal for environments that are prone to corrosion and can be adjusted to supply the air in a swirl pattern (default), directional patterns and vertical downward patterns.

Product Description

AXO-ALU aluminum high induction swirl diffusers by EffectiV HVAC are designed to be used in air conditioning, ventilation and 1 1/10 heating systems, in environments that are more susceptible to metal rust. 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-ALU-C round swirl diffusers are available in 12″, 16″, 20″, 25″ and 32″ (300, 400, 500, 625 and 825 mm) face diameters.
