The environmentally friendly FBD mine explosion-proof axial flow partial ventilator reduces the noise of various frequencies to below 85 to 80 decibels, protects the physical and mental health of workers, improves the underground working environment, and realizes environmentally friendly ventilation in the mine.

The environmentally friendly bureau fan is a new type of product that improves the design on the basis of the low-noise bureau fan with side air intake. The noise is less than 80 decibels. The noise reduction measures taken by the low-noise and environmentally friendly bureau fan are based on the principle of noise generation and propagation, change the air intake direction, optimize the structural design, and make the overall noise of the fan eliminated and attenuated through better adsorption of medium and low-frequency noise and efficient isolation of high-frequency noise.The modular design composed of a combination of various silencer components can provide users with better options for purchase and transformation.

1. Scope of application

FBD series mine explosion-proof press-in type counter-rotating axial flow partial ventilator, suitable for coal mines, metal mines, chemical mines and other industrial sectors to transport coal containing gas, coal dust and explosive hazards in the mine air inlet roadway, used in conjunction with positive pressure air ducts for press-in ventilation; it can also be used as ventilation equipment for tunnel construction.
