Jet Fans ARC-AUC

The ARC-AUC are height-saving reversible (ARC) and unidirectional (AUC) tunnel fans for ventilation of aggressive atmospheres such as road traffic and train tunnels. In addition to performing standard ventilation they double-function as part of the fire-fighting resources and are tested and approved to meet requirements for smoke exhaust.

The design is characterised by a space-saving rectangular design and employs the renowned NovAx axial flow fans. Compared to standard round tunnel fans, the installation height is approximately 20% less. This is particularly effective in the case of rectangular tunnel profiles where the height of the technical installations is normally very limited.
