How the model reads against this maker's data

Ziehl-Abegg FE2owlet axial fans read from their own product pages

30 listings (Ø250–910, ECblue and AC); 4 with curves

every listing's design point and nameplate power are the page's printed optimum; a curve is listed only where the article's own printed maxima and optimum sit on the chart — the FN025 and FN030 4IA articles do, within 0.1 / 0.8 / 1.2 % (head, foot, optimum) — and its power curve peaks within 1.5 % of the duty table's curve-I figure; the solver reads the printed P1 back at the design point within 1 %

From the validation page; every row is held by a test.

Listed from published data; a listing's figures are the manufacturer's, the model that runs them is ours. Solver results never depend on who has claimed what.
