At the heart of the fan’s noise reduction prowess lies the ingenious panel-type muffler structure. Flexible materials envelop the entire exterior of the airflow channel, effectively absorbing and dampening the high-speed airflow’s noise. This results in a significantly quieter operation, creating a more harmonious work environment. Moreover, the replaceable muffler cotton ensures sustained noise reduction throughout the fan’s lifespan.
Beyond its noise-reducing capabilities, the mining flame-proof compressed-in counterrotating local axial flow fan excels in performance. The meticulously designed flow path, characterized by consistent outer diameters from the fan rectifier cap to the rear muffler cone, ensures a smooth and unobstructed airflow. This streamlined design minimizes resistance, leading to an improved pressure coefficient and a remarkable increase in airflow rate and wind distance.
