I have yet to see proper pictures of the air ‘brakes’ … but the way you picture it doesn’t cause a cyclone effect anymore.
The air comes straight onto the coil and when it collides, it’ll go in both directions. This will also prevent the flavor molecules being ejected from the non-spinning flow and provide better flavor.
Just my 2 cents, based on what you show me here, not the actual product.
So from what I see, it doesn’t make sense that you get the cyclone effect in picture D
