Ruck EM DUO - noise insulated duct fans

The powerful and quiet Ruck EM DUO circular duct fans are fitted with a high-performance, energy-efficient EC motor with low power consumption. The Ruck EM DUO duct fan comprises diagonal fans from the Etamaster series with three-dimensionally shaped impeller blades. The result is the highest possible aerodynamic efficiency. Variable installation positions are possible – both horizontally and vertically. The connection spigots are fitted with seals for easy installation into ventilation ducts.

The Ruck EM DUO fan casing is made of galvanised sheet steel and is sound-insulated. Ruck EM DUO duct fans are controlled via 0–10 V using potentiometers.
