Diffusers at Low Wind Speeds
Why is it that at low wind speeds, air comes out of only one diffuser?
At low wind speeds, the windmill might only be producing .5 to 1.0 CFM (cubic feet per minute) of air. This is sufficient for one diffuser, but probably isn’t enough air to operate two diffusers. As your wind speed picks up, the second and even third (if you have one) diffusers should kick in if your valves are adjusted appropriately
