The unique design of the multiple discharge scroll far exceeds the efficiency levels of conventional EC plug fans.

• Fan systems which are arranged in a row or stacked form a multiple wall configuration - a socalled fangrid

• Fans made using hybrid design with an integrated re-direction device are particularly suitable for creating multiple wall configurations, as this facilitates air flows to the outlets one to another more easily. In comparison with free-running fans, there will be no significant installation wastage.
