ARR-AUR
The ARR-AUR series provides highly reliable, smoke-approved tunnel ventilation for demanding road and rail environments, available as reversible (ARR) or unidirectional (AUR) fans. Built on the proven NovAx™ platform, they ensure efficient daily ventilation and reliable smoke control during fires, featuring circular silencers for low sound levels. Accessories such as wire guards and aerodynamic deflectors are available.
These dual-function tunnel jet fans are built on the reliable NovAx™ axial flow platform, suitable for both normal ventilation and emergency smoke control.
Available in reversible (ARR) and unidirectional (AUR) versions, which can include optional wire guards and deflectors.
As a standard, the tunnel jet fans have round silencers of 1220 mm on each side. Jet fans with shorter or longer silencers are available on request.
A special rectangular design is also available for projects requiring extreme low installation heights.
