Product Description
Pneumatic System
Equipped with optimized three-dimensional blades with aerodynamic profile (made of forged aluminum alloy) for minimal aerodynamic losses and stable efficiency under any operating conditions; single-stage impeller design ensures a streamlined shape and unobstructed airflow passage.
Explosion-Proof Core
Includes an explosion-proof motor (ExdI Mb class) with a hermetically sealed motor chamber separated from the air duct to prevent spark leakage, making it suitable for use in environments with methane and coal dust explosion risks in coal mines.
Transmission Design
Direct connection between the motor and impeller eliminates redundant components such as long shafts and pulleys. Provides 99% transmission efficiency, reduces failure points and improves operational stability.
Protective Configuration
Motor protection class IP55, insulation class F. Resistant to moisture, dust and corrosion, suitable for harsh underground coal mine conditions (temperature range from -20°C to 40°C).

Frequently Asked Questions (FAQ)
Q
What makes this fan suitable for coal mine environments?
The fan features an explosion-proof motor (ExdI Mb class) with a hermetically sealed motor chamber that prevents spark leakage. It is specifically designed to operate safely in environments with methane and coal dust explosion risks, meeting the strict safety requirements of underground coal mines.
Q
What is the operating temperature range of this fan?
This coal mine fan is designed to operate reliably in temperatures ranging from -20°C to +40°C, making it suitable for the harsh and variable conditions typically found in underground mining environments.
Q
What is the motor protection class and why does it matter?
The motor carries an IP55 protection rating with insulation class F. IP55 means the motor is fully protected against dust ingress and water jets from any direction, ensuring long-term reliability in wet, dusty, and corrosive underground conditions.
Q
How does the direct-drive transmission improve performance?
The direct connection between the motor and impeller eliminates intermediate components such as long shafts, belts, and pulleys. This results in a 99% transmission efficiency, significantly reduces mechanical failure points, lowers maintenance requirements, and ensures more stable and consistent fan operation.
Q
What material are the fan blades made of, and what are the benefits?
The fan blades are crafted from forged aluminum alloy with an optimized three-dimensional aerodynamic profile. This material choice ensures lightweight construction combined with high strength, while the aerodynamic design minimizes airflow resistance and maintains stable ventilation efficiency across varying operating conditions.
Q
Is this fan suitable for both main ventilation and local ventilation in mines?
Yes. Thanks to its single-stage impeller design, explosion-proof certification, and robust protective configuration, this fan is well-suited for a variety of ventilation applications in coal mines, including main tunnel ventilation, auxiliary ventilation corridors, and localized ventilation in working faces.
