Aerofoil Axial Flow Fan for Mining/Tunnel Ventilation
The TDJ series low-noise tunnel fan is a dynamic and tunable two-stage impeller counter-rotating.
Two special impellers equipped with imported SKF Swedish bearings directly drive two
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 a special motor
equipped with imported SKF Swedish bearings.
Tunnel construction ventilators are widely used in railway tunnels, highway tunnel
water conservancy construction projects, ventilation, ventilation equipment for mines,
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 operating
cost of the fan. The fan is allowed to run in reverse wind, but the impeller must be started
after the impeller 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 requirements of explosion-proof technical conditions,
and the explosion-proof standard dI.
This series of wind tunnel fan has a wide adaptability and long service life,
and 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 characteristics of waterproof, flame retardant, anti-static, heat-resistant and cold-resistant,
anti-aging, anti-mildew, etc., and the friction resistance coefficient is lower than 0.015,
under good construction management conditions, the average leak rate of 100 meters is between
1% and 1.3%.

Customer Cases---Tunnel Site
We've been working with many project in Indonesia, Pakistan and other countries for tunnel,
mining and Hydro Electric Power Plant.We understand the harsh environments in which fans are used.
Motexo fans will meet and exceed the demands of your mine or tunnel project, other industrial factory.
Motexo Fan manufacture 300 series and more than 1,400 kinds of industrial fans.
All include heavy-duty designs for industrial applications.
We have individual workshop for roots blower,centrifugal fans&blowers,
maintaining,axial fan,welding and assembling.
Not only we can produce large batch of small fan, we have processing capability to produce heavy
duty blowers like above 3.5m high. We adopt the best technology in all aspects of industrial blower,
such as shot blasting, sand blasting, all the paint process, welding process, etc.
Stoving vanish looks brighter than water paint( ordinary painting color).
It has more than 200 sets of fine, large and rare processing equipment, and has a high-tech
resin sand casting production line.
Our equipment is generally used for power plants, environmental protection plants, coal plants, and so on.
It requires high technology and workmanship.
