Available static head
In case of ducted installation the total pressure drops in the inlet and outlet ducts can not exceed the maximum available static head.
The minimum duct section must guarantee that the medium air velocity does not exceed 2,5 m/s in order to avoid noise problems and to keep
the pressure drops as lower as possible.
The rotational speed of the fans can be increased compared to the factory setting in order to increase the available static head up to the
maximum available value reported in the table.
