tunnel Axial Flow Fan humidin

Tunnel fans are an axial flow fans and moves an airstream along the axis of the fan. The air is pressurized by the aerodynamic lift generated by the fan blades, made like a propeller or an airplane wing. These fans are used as the ventilation systems in a tunnel

AXIAL & JET FANS FOR TUNNEL VENTILATION

AXIAL FANS According to the design of the tunnel ventilation system, axial fans are commonly used exhausting polluted air and fumes in case of a tunnel fire, but also blowing fresh air inside the tunnel. Axial fans can be uni-directional type (our “ZVN”series) or fully reversible type (our “ZVR”series).

Axial fan design Wikipedia

An axial fan is a type of fan that causes gas to flow through it in an axial direction, parallel to the shaft about which the blades rotate. The flow is axial at entry and exit. The fan is designed to produce a pressure difference, and hence force, to cause a flow through the fan.Factors which determine the performance of the fan include the number and shape of the blades.

FläktGroup Road Tunnel Ventilation

The most common method is to use Jetfoil fans where the relatively high velocity discharge induces a flow of air through the tunnel. As the jet from the fan diffuses, it transfers energy to the tunnel airflow and creates an increase in static pressure, which causes air to flow as in any conventional system. Large axial flow fans are used for
