Main Features

1) Simple structure in linear type ,easy in installation and maintation. 

2) Adopting advanced world famous motor brand   ,electric parts and operation parts. 

3) All new, energy saving, high efficiency, and low noise. 

4) Running in a high automatization and intellectualization,no pollution 

5) The static pressure efficiency of single-stage series fan and counter-rotating series fan devices is as high as above 80%, thus the high efficiency area is wide and energy saving effect is obvious. . 

twisted blades

Name: Bliwing Cylinder 

The fans of various series all use the simplest transmission device of direct connection between motor and impeller. 

 Wing twisted blades are used, which have high aerodynamic efficiency. The static pressure efficiency of single-stage series fan and counter-rotating series fan devices is as high as above 80%, thus the high efficiency area is wide and energy saving effect is obvious.

Machine Parts

 Fans for mines select explosion-proof motors and put motors in isolating chambers of fans to ensure the isolation between wind current and air flow containing gas in fan flow channel and meanwhile, play heat dissipation and diversion function. The wind current pipe makes the surrounding area of motor is connected with atmosphere, which both increases the safety performance of motor and directly dissipate the heat of motor to air and improve the safety of fan operation.  

Main Features

This series of fans are counter-rotating explosion-proof main fans. The primary and secondary blades of fans use three-dimensional twisted blades with adjustable incidence angles respectively. The air volume is large, air pressure is high and air volume and air pressure are adjustable. Air volume scope is Q=720m³/min-48000 m³/min and static pressure scope is Pst=400Pa-5950Pa, applicable to the ventilation of large and medium coal mines.
