The Duco RoofFan is a pressure-controlled roof fan that provides collective drainage within Duco’s demand-driven Natural Ventilation Systems (VNV). The pressure-controlled system ensures a perfect distribution of the flows in stacked housing construction. In combination with the Intelli AirValve or iAV, the Duco RoofFan offers the solution for the first fully demand-driven collective C system.
This roof fan has a capacity of 3,000m³/h at 150Pa and consumes on average up to 55% less energy thanks to its advanced motor. The Duco RoofFan was specifically developed for renovation and new construction projects with 6 to 12 flats (3 to 6 storeys high).
