The NOVENCO® tunnel jet fans are for installation in large road, metro and train tunnels, where the transport and removal of exhaust gases as well as ventilation is essential for the comfort and safety of users, cars or rolling stock. In case of fires, the jet fans double-function as invaluable aids for the fire-fighting services and help contain and control the spread of smoke.
The NOVENCO experience with the NOVENCO NovAxTM-based design, manufacture and installation of tunnel fans dates back to the 1980s. The ventilation principles remain unchanged today, as induction of impulses sets air in motion and push it through the tunnels longitudinally.
Ventilation system designs with tunnel jet fans are ductless and may include auxiliary fans for supply and exhaust of air. The systems have low construction cost and good space utilisation.
The NOVENCO tunnel jet fan series are available as unidirectional or reversible units. All versions include silencers. The range of sizes and capacities cover medium to high thrusts.

Jet Fans ARC-AUC
The ARC-AUC are 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.
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.
