Straight Duct Before a VAV Inlet
Provide the straight, stable inlet condition shown by the terminal-unit manufacturer and project design so the sensor and damper see usable airflow.
Stop if
- This VAV inlet is close to [elbow/tap/transition]. Does the approved detail allow this arrangement, or do we need more straight inlet before the box?
Watch out
- Do not assume every VAV tolerates an elbow or flex connection directly at the inlet.
Check
- Confirm VAV model and inlet size
- Review required inlet arrangement
- Avoid abrupt elbows, taps, or crushed flex at the inlet
- Support the connection independently
- Coordinate access to sensor tubing and controls
