Comparing Standard vs High Induction Diffusers – Impact of Airflow Angle

February 19, 2019

In this video we used smoke tests to compare standard diffusers (3 Cone and Plaque) and High Induction Diffusers (AXO and PLAY), and the impact that the angle of airflow entering the diffuser has on air diffusion.

These are visual measurements based on a single smoke test per product, in order to evaluate how high induction diffusers can offer a more reliable airflow independently of installation constraints.

Getting up to 99% – almost double – more air coming out of one side of the diffuser will have multiple negative effects:


In addition to offering a higher air induction ratio and better efficiency, high induction diffusers also allow us to significantly reduce these negative effects.
