Select Air Outlet Type

Choose the catalog / air outlet type you want to work with. Select it here once; the Selection Engine will use this catalog automatically. The selected catalog controls the application list, performance database and product-specific selection rules.

Airflow (CFM)

Selection Method / General Criterion

Choose ONE method only. When Rule 1 or Rule 2 is selected, the Application field is not used.

Application

Known sheet width?

No Yes

Hard constraints
Airflow tolerance is ±50 CFM. For Square Diffuser, Rule 1 = Vk ≤ 850 FPM / NC ≤ 30 and Rule 2 = Vk 850–1600 FPM / NC 30–45. Optional physical-neck limit applies when sheet width is known.

Ranking
Smallest valid catalog size → exact/above CFM → closest CFM → lower Vk → lower NC.

Products module is reserved for the next platform phase.
