To add to what esshup said, on a windmill system the air volume varies with wind speed. So try to put multiple diffusers at the same depth. Otherwise most of the air will go all to the shallowest diffuser in low wind conditions.

A regulating manifold will not be as effective at dividing air fow like it can in a constant air flow situation like with an electric system.
