What do I do if a zone is starved for air and the balancer says my fitting is causing turbulence?

Inspect the interior of the problematic fitting using a small mirror tool or borescope camera. Check if a splitter damper or internal acoustic lining layer has come loose and flipped across the air stream. * If the fitting design itself is the issue (such as a square throat elbow built without turning vanes), you must modify the run on-site by retrofitting engineered turning vanes inside the turn or replacing the choked fitting with a smooth radius transition turn.
