The table shows fan capacity measured at static pressure P=20 Pa.
When the static pressure is less than 20 Pa the increase of blade angle is considered to increase fan capacity.
Example for the 10W motor:
impeller 230/22° - air flow 500 m3/h;
impeller 230/28° - air flow 630 m3/h;
impeller 230/34° - air flow 820 m3/h.

Impeller width:
Impeller diameter ≤ Ø230 mm - 0.80...0.84 mm.
Impeller diameter Ø250 and Ø254 mm - 0.85...0.90 mm.
Impeller diameter Ø300 mm - 1.05...1.10 mm.
