Tunnel Jet Fan

The fan is mainly used for ventilation of underground railways, railway tunnels, caves, underground engineering and buildings and so on.

Application

The fan is mainly used for ventilation of underground railways, railway tunnels, caves, underground engineering and buildings and so on.

Advantages

* It has the characteristics of high efficiency, high performance, low noise and high temperature resistance
* Single direction and reversible for options.
* The silencer is a two-layer cylindrical structure with the inner perforated plate and the outer steel plate. The middle is filled with flame-retardant and moisture-resistant polish fiber material.
* The axial impeller is made of 400tons die casting aluminum alloy material with high desity. It pass dynamic test and X-Ray test to confrim safe operation of fans.
* The surface of the fan housing which treated with anti-corrosion and anti-rust treatment to ensure long-term anti-corrosion operation.

Remark	1. The listed technical specification performance is according to the standard working situation, Temperature 20℃,Density 1.2kg/m3, pressure 101324Pa. 2. The listed Noise was tested by the fan in open space and in the front of 10m of the fan outlet with 45°, if the test distance moves in the front of 3m of fan outlet, then 10dB(A) should be added. 3. The listed Noise was tested by the fan's inlet and outlet with 1D silencers, if change the silencers to 2D, then 3dB(A) should be reduced.
