Introduction to environmentally friendly, low-noise FBD axial flow local ventilation fan

2025-04-22

The environmentally friendly FBD low-noise axial local ventilation fan is a super low-noise, environmentally friendly ventilation fan developed by our company. This series of fans adopts multiple noise reduction measures. Based on the aerodynamic principles of the fan and the principles of noise generation and propagation, streamlined air intake silencers and inlet/outlet composite silencers have been added.

The environmentally friendly FBD low-noise axial flow local ventilation fan is a super low-noise, environmentally friendly ventilation fan developed by our company. This series of fans adopts multiple noise reduction measures. Based on the aerodynamic principles of the fan and the principles of noise generation and propagation, it adds a streamlined air intake silencer and an inlet and outlet composite silencer. The fan host is optimized in structural design. By adding high-quality sound-absorbing materials, better adsorption of mid- and low-frequency noise and efficient isolation of high-frequency noise are achieved, so that the overall noise of the fan is eliminated and attenuated; the noise of various frequencies of the fan is reduced to below 85 to 80 decibels, protecting the physical and mental health of on-site personnel, improving the working environment in the mine, and achieving environmentally friendly air supply.

Patent No.: ZL 2020 21223212.3 “A type of low-noise counter-rotating axial flow ventilation fan”.

Noise Reduction Principle:

The noise reduction advantage of the fan we designed adopts a comprehensive noise reduction method; starting from the fan performance, structure, and materials used; first, ensuring reliable operation and air volume, scientific noise reduction is carried out; using our company's unique silencing and noise reduction technology, multiple sound-absorbing materials and silencing processes are integrated into the equipment. The noise reduction measures are based on the principles of noise generation and propagation, changing the air intake direction, optimizing the structural design, achieving better adsorption of mid- and low-frequency noise and efficient isolation of high-frequency noise, so that the overall noise of the fan is eliminated and attenuated; Patent No.: ZL 2020 2 1223212.3.
