For France, in several applications aluminum fans are mandatory. Aluminum fans do not have the same aerolical efficiency as composite fans. Because of this difference in aerolical efficiency (and to a lesser extent the weight of the fan impellor), the SFP and maximum airflow is different as well.
Specifically in French, we have now published a technical documentation for GLOBAL PX and GLOBAL LP units, equipped with aluminum fans.
