Usage
The TDJ series low-noise tunnel fan is a dynamic, tunable, two-stage counter-rotating impeller fan. Two special impellers equipped with imported SKF Swedish bearings drive two different impellers directly.

The TDJ series low-noise tunnel axial flow fan is also movable and can be calibrated for single-pole impeller rotation.

A single-stage impeller is directly driven by an individual motor equipped with imported SKF Swedish bearings.

Tunnel construction fans are widely used in railway tunnels, water conservancy projects in highway tunnels, ventilation equipment for mines and power stations, and other underground construction projects.

As the tunneling depth increases, different fan performances are obtained by adjusting the blade mounting angle, and the flow pressure is gradually increased, thereby reducing the fan's operating cost. The fan can run in reverse wind, but the impeller must start after it is completely stationary.

The conveying medium is air, the dust content is <150mg/m3, the working temperature is -20~40°C, and the relative humidity is <95%.
For the construction requirements of explosion-proof engineering, the fan is designed and manufactured according to the needs of explosion-proof technical conditions and the explosion-proof standard dI.

This series of wind tunnel fans is highly adaptable and has a long service life. It is an ideal replacement for ventilation equipment in tunnels, mines, and related engineering fields.

The matching ventilation hose adopts high-strength cross-feeding industrial back-feeding. The maximum tensile strength of the material can reach 3000N/5cm2. It has the features of waterproof, flame retardant, anti-static, heat-resistant and cold-resistant, anti-aging, and anti-mildew, and the friction resistance coefficient is lower than 0.015 under the right construction management conditions, the average leak rate of 100 meters is between 1% and 1.3%.
