Product Video
Product Description
Pneumatic System
Equipped with optimized three-dimensional aerodynamic blades (forged aluminum alloy) for minimal aerodynamic losses and stable efficiency under any operating conditions. The single-stage impeller design ensures a streamlined shape and unobstructed airflow.
Explosion-Proof Core
Features 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 environments with methane and coal dust explosion risks in coal mines.
Transmission Design
Direct coupling between the motor and impeller eliminates redundant components such as long shafts and pulleys. Achieves 99% transmission efficiency, reduces failure points, and improves operational stability.
Protective Configuration
Motor protection rating IP55, insulation class F. Resistant to moisture, dust and corrosion. Suitable for harsh underground coal mine conditions (operating temperature range: -20°C to 40°C).

Frequently Asked Questions
Q
What explosion-proof certification does this coal mine fan comply with?
The fan is equipped with an explosion-proof motor certified to ExdI Mb class, which meets the safety standards for use in underground coal mines where methane gas and coal dust explosion risks are present.
Q
What is the operating temperature range of this fan?
The fan is designed to operate reliably in temperatures ranging from -20°C to 40°C, making it well-suited for the harsh and variable environmental conditions found in underground coal mines.
Q
What is the transmission efficiency of this fan?
Thanks to the direct-drive design — where the motor is directly coupled to the impeller — the fan achieves up to 99% transmission efficiency. This eliminates the need for long shafts and pulleys, significantly reducing mechanical losses and potential failure points.
Q
What is the IP protection rating of the motor?
The motor carries an IP55 protection rating with insulation class F. This ensures effective resistance against dust ingress and water jets, as well as protection against moisture and corrosion in underground mining environments.
Q
What material are the fan blades made of, and why?
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, minimizing aerodynamic losses while maintaining stable performance under varying operating conditions.
Q
Is this fan suitable for long-term continuous operation in coal mines?
Yes. The single-stage impeller design, direct-drive transmission, IP55-rated explosion-proof motor, and robust protective configuration collectively ensure that the fan can sustain reliable, long-term continuous operation in demanding underground coal mine environments with minimal maintenance requirements.
