Below are the detailsExplosion proof compression type counter rotating axial flow local ventilation fanA brief introduction

　　form:

　　The FBD series fan consists of two sets of working motors, with two-stage impellers rotating relative to each other. The first stage impeller rotates clockwise, while the second stage impeller rotates counterclockwise. Air enters the first stage impeller through the collector to obtain energy and directly enters the second stage impeller. After being pressurized, it is sent out. The role of the secondary impeller is not only to increase the energy of the airflow, but also to have the function of static guide vanes in other types of axial flow ventilation. While obtaining the velocity component in the circumferential direction of the guide, it not only streamlines the energy of the airflow, but also reduces noise.

　　Main characteristics of FBD mining press in counter rotating axial flow local ventilation fan

　　1. High efficiency: The FBD series fan is well-designed and technologically advanced. Its blades adopt a ternary fluid design, forming a twisted wing shape. The high-efficiency operating area of the fan is large, ensuring that the operating fan is always within the high-efficiency working range.

　　2. Low noise: The FBD series fan adopts a counter rotating direct drive, which reduces the guide vane device compared to the old fan. It increases the fan pressure while straightening out the direction of air flow, reducing air friction noise. The casing adopts an external compound noise reduction device, and the overall operating noise can be controlled below 85 decibels (below 35 decibels compared to A-level), with ultra-low noise characteristics, and has a significant effect on changing the noise environment of underground confined spaces;

　　3. The wind pressure is relatively gentle, with minimal surge phenomenon. It operates stably in areas with high wind pressure and low flow rate, and has a long distance for underground air supply, making it highly adaptable to complex tunnels.
