Fläkt Woods range of AXIJET / Jetfans and AXICENT / Large JM fans have provided solutions worldwide for:

• Road Tunnels - removal of pollution and smoke.
• Metro and Underground Railways – removal of heat, general ventilation and fire smoke control, including anti-stall devices to accommodate pressure pulses.
• Tunnel and Underground Construction - providing fresh air and removal of pollution, heat and dust.
• Wind Tunnels - for aeroacoustic, climatic and aerodynamic testing.

Our offering for these projects can range from just equipment supply to the provision of a complete sub-system. A typical offering can include dampers, attenuators, transformations sections, fans, anti-vibration equipment and starters / inverters.

System optimisation is based on detailed knowledge of the individual system components and the interaction between them. Design calculations are also performed to confirm both aerodynamic and acoustic performance.
