Jet Fans ARR-AUR

The ARR-AUR are reversible (ARR) and unidirectional (AUR) 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 the circular silencers and employs the renowned NovAx axial flow fans.
