The new RQM MultiEvo combines the compact design of plug fans with the benefits of traditional cased fans. In principle, it is a directly driven centrifugal fan with spiral shaped guide vanes. 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.
