Using a large single fan, depending on the manifold design behind it, and possibly not even requiring the manifold, air is withdrawn from behind the protective backsplash cowling, where it will pull in air from a great length on either side as it overcomes pressure in the center, resulting in adequate exhaust along all, or nearly all, of the sink all the time. As previously suggested, the smoke test will tell all.
