Mining flameproof compressed-in counterrotating local axial flow fan incorporates a multi-layered design to achieve exceptional performance. Here’s a closer look at its key components:

Noise Reduction:
Panel-Type Muffler Structure: The fan employs a unique noise reduction system. The entire flow channel is encased in flexible materials, significantly dampening the high-frequency noise generated by airflow. This results in a quieter operation compared to traditional fans.

Optimized Flow Path:
Consistent Diameters: To ensure smooth airflow throughout the fan body, the outer diameters of crucial components are meticulously maintained. This consistency applies to the fan rectifier cap, muffler core, motor base, and rear muffler cone. This design feature enhances the fan’s pressure coefficient, ultimately increasing wind delivery rate and effective distance.

Serviceable Muffler System:
Replaceable Muffler Cotton: The panel-type muffler structure utilizes a clever mounting system for the sound-absorbing cotton. This fixed-and-movable design allows for easy replacement of the cotton when it becomes worn, ensuring optimal noise reduction throughout the fan’s lifespan.
