TUNNEL FANS

Tunnel fans are for ventilation and fire control in tunnel facilities. The units use the impulse principle to move air through the tunnels, which then function as oversized ducts. Some system designs include axial flow fans for supply or exhaust. Ventilation with tunnel fans have low construction cost and good space utilisation.
The Novenco Tunnel Fans series are available as unidirectional or reversible units with silencers. Designs are square or round with thrusts between 105 and 3002 N, rated power from 2.2 to 90 kW and sound pressures from 80 to 106 db(A). All tunnel fans are certified for 200°C, 300°C and 400°C according EN 12101 part 3.


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.

The design is characterised by the rectangular silencers and employs the renowned NovAx axial flow fans.
