The FBCDZ series explosion-proof counter-rotating mine ventilation fan is engineered for maximum efficiency, safety, and reliability in underground mining operations. Its dual-impeller counter-rotating design ensures optimal airflow adjustment, reducing energy loss while maintaining high-performance ventilation. The fully sealed motor chamber isolates the explosion-proof motor from the airflow, significantly enhancing operational safety. With advanced blade and hub design, including high-strength materials and precision balancing, this fan minimizes vibration and noise, ensuring smooth and stable performance. Integrated temperature monitoring and alarm systems further enhance reliability, making it an excellent choice for demanding mining environments.
This high-efficiency, low-noise ventilation fan is developed in collaboration with Northwestern Polytechnical University, featuring advanced double-sided swept-back airfoil blades. With an efficiency of 70-75% and noise levels 5-8 dB lower than similar products, it ensures optimal performance in mining environments. The fan incorporates multiple noise reduction technologies, including a silencing collector, pre-installed silencers, and an extended silencing diffuser, effectively reducing noise to 75 dB(A). Comprehensive noise control measures lower sound emissions by 20-30 dB, ensuring a quieter and safer underground workspace.
This compact and energy-efficient ventilation fan features a swept-back blade design, optimizing aerodynamics for high performance. It supports multi-stage operation and adapts to various ventilation networks, maintaining long-term high efficiency. The direct-drive impeller ensures stability, easy installation, and minimal maintenance. With reversible airflow capability exceeding 60%, it eliminates the need for additional reverse air tunnels. Built with moisture-resistant steel-welded housing and high-strength materials, it withstands harsh underground conditions. Low noise emissions and an adjustable blade angle make it an ideal solution for dynamic mining operations.
