Tunnel Ventilation Fans

The need for tunnel ventilation is critical for the life and safety of any person utilizing the metro, rail or road tunnels throughout the world. Typically the equipment is used for smoke extraction or control for the time it takes people to evacuate the tunnel under emergency conditions. They are also utilized to control exhaust fumes and to Get price

An overview of flat belt conveyors and maintenance

As automated carwashing has grown, the conveyor system has become even more important. And, as vehicle technology has evolved, new types of wash conveyors, including flat-belt systems, have developed. Upgraded conveyor options safely move vehicles of all shapes and sizes through modern wash tunnels that utilize multiple pieces of effective equipment. Get price

Tunnel fan See all our tunnel ventilation fans with fire

Tunnel fans are designed for ventilation and smoke control in road- and train tunnels. The jet fans use the impulse principle to move air through the tunnels in longitudinal direction. Some system designs include axial flow fans for supply and/or exhaust. Ventilation with tunnel jet fans has low construction costs and good space utilisation. Get price

Tunnel

Motor vehicle tunnels usually require ventilation shafts and powered fans to remove toxic exhaust gases during routine operation. Rail tunnels usually require fewer air changes per hour, but still may require forced-air ventilation. Both types of tunnels often have provisions to increase ventilation under emergency conditions, such as a fire. Get price
