FBCZ Series Explosion-Proof Extractive Axial Flow Main Fan Manufacturer for Coal Mines
FBCZ Series Explosion-Proof Extractive Axial Flow Main Fan is designed for the main ventilation systems of small and medium-sized coal mines. It features direct motor-impeller connection, enclosed motor protection, reversible airflow, adjustable blade angle and stable operation under different mine ventilation network resistance conditions.
Product Introduction
The FBCZ Series fan, formerly known as BK54 and BK55 Series, is developed according to the ventilation network parameters of small and medium-sized coal mines. It is mainly used as a dedicated main fan for coal mine ventilation systems where explosion-proof performance, stable exhaust airflow and reliable long-term operation are required.
Compared with traditional belt-driven or long-shaft mine axial fans, this series adopts a direct connection structure between the motor and impeller. The simplified transmission arrangement helps reduce mechanical complexity, improve maintenance convenience and support stable operation in demanding underground ventilation projects.
Structural Features
The motor and impeller are directly connected, avoiding the complex belt drive or long-shaft transmission structure. This design supports easier inspection, simpler maintenance and more reliable operation for coal mine main ventilation.
A fully enclosed cooling cover and air pressure balance pipe are installed outside the motor, helping the motor operate in non-gas airflow and meet the working requirements of coal mine explosion-proof ventilation systems.
The fan uses a single-stage working wheel structure. Rear guide vanes are arranged between the fan and diffuser to improve static pressure efficiency and organize airflow more effectively.
The fan can reverse airflow by reverse rotation. Reverse airflow can reach about 65%–85% of normal airflow, reducing the need for a separate reversing air duct and helping save civil construction investment.
The impeller blade installation angle can be adjusted according to production and ventilation requirements, making the fan more adaptable to different mine operating conditions.
The fan is designed with a stable performance curve without a hump zone, allowing stable operation under different mine ventilation network resistance conditions.
Reference Technical Parameters
The following model data is for preliminary selection reference. Final fan selection should be confirmed according to mine ventilation network resistance, required airflow, static pressure, installation condition and power supply requirements.
Application Scenarios
This fan is suitable for coal mine ventilation systems that require reliable main exhaust ventilation, fast air reversal, stable operation and explosion-proof structural design. It is especially suitable for projects where simplified transmission, reduced civil construction cost and convenient maintenance are important purchasing considerations.
