Motexo Vent--

Two-stage Counter Rotating Fan 110KW

DSSF series (two-speed) counter-rotating-type counter-rotating axial-flow tunnel ventilator is
mainly used in high-speed rail, expressway, railway, diversion tunnel metal mine tunnels, and other fields. The temperature of the conveying medium does not exceed 60 ° C,
the temperature is not more than 95 ± 3% (25 ° C) and non-corrosive.

This series of curved-sweep combined orthogonal tunnel special counter-rotating shaft flow fans are mainly used for tunnel construction ventilation in highway and railway hydropower projects, as well as other underground construction ventilation.

Structure and its characteristics

• The series of fans have a current collector, a primary fan, a secondary fan, a motor,
  a muffler, and the like. The body and structure are welded by steel plates.
  The impeller is made of aluminum alloy die-casting. The fan adopts the direct
  connection of electric motor and impeller. The transmission is reliable, the overall
  structure is simple and compact, durable, and durable. It is safe to use and easy to maintain.

• It adopts international advanced ternary flow aerodynamic theory,
  and other high-tech design and manufacturing such as pulsing combined orthogonal
  blades and airfoil, which has advanced levels at home and abroad.

• It has the characteristics of compact structure, low noise, high efficiency,
  good wind performance, high wind pressure, stable operation in the working area, and wide application range. According to the length of the tunneling surface and
  the different ventilation requirements of the roadway, it can be used in the whole
  machine and can be used in stages to reduce energy consumption.
  Energy conservation is the ideal equipment for local ventilation of tunnels in the midfield.

• Adopting an outsourced double-type muffling device with ultra-low noise and
  other characteristics, and the sound-absorbing effect is good.

Customer Cases---Tunnel Site

We've been working with many projects in Indonesia, Pakistan, and other countries for the 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, another industrial factory.






Production Workshop

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 workshops for roots blower, centrifugal fans&blowers,
maintaining, axial fan, welding, and assembling.



Production&Testing Equipment

Not only we can produce a large batch of small fans, but we also have the 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, sandblasting, all the paint process, welding process, etc.
Stoving varnish 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.
