Product Description

Mine Fan Series

TNF series Tunnel Fan in Normal Tunnel Operation

SDF tunnel press-type counter-rotating fan is mainly used for high-speed rail, highways, railways, diversion tunnel, metal mine and other fields. Drive air in outside(press-in type) through vent pipe. Gas temperature can't exceed 80 ºC, and must be non-corrosive gas.

Structure and Features
A. The series of fans include air collector, class I main fan, class II main fan, silencer, motors, venti pipe interface and other components. The body and the structure are made of welded steel plate, the impeller adopts wing streamlined blade, the fan adopts the motor and the impeller direct connection way, the transmission is reliable, the whole structure is simple compact, sturdy and durable, safe use and convenient for maintainance.
 
B.Compact structure, low noise, high efficiency, good wind performance, high wind pressure, stable operation in the work area, wide application range and so on. According to the length of the digging surface and the different ventilation requirements of the roadway, you can use the machine, but also graded use, thereby reducing energy consumption, tunnel tunneling is the ideal local ventilation equipment.
 
C. According to the specific requirements of the tunnel project, the company can set the diameter in the fan inlet part, and then with the front fan docking, in order to achieve long-distance tunnel relay air to achieve better ventilation effect.
