Product Description
-
Pneumatic System Equipped with optimized 3D aerodynamic blades (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 Features an explosion-proof motor (ExdI Mb class) with a hermetically sealed motor chamber separated from the air duct to prevent spark leakage — 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 (FAQ)
-
Q What explosion-proof certification does this coal mine fan have?The fan is equipped with an explosion-proof motor certified to ExdI Mb class, making it fully compliant with safety requirements for use in underground coal mines where methane and coal dust explosion risks are present.
-
Q What material are the fan blades made of, and why?The blades are made from forged aluminum alloy with a 3D aerodynamic profile. This material choice ensures lightweight construction, high strength, and minimal aerodynamic losses for maximum ventilation efficiency.
-
Q What is the transmission efficiency of this fan?Thanks to the direct-drive design — where the motor connects directly to the impeller without belts, pulleys, or long shafts — the transmission efficiency reaches up to 99%, significantly reducing energy loss and mechanical failure points.
-
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 suitable for the harsh environmental conditions typically found in underground coal mines.
-
Q What is the IP protection rating of the motor?The motor carries an IP55 protection rating with insulation class F, providing robust resistance against dust ingress, water jets, moisture, and corrosion — ideal for demanding underground environments.
-
Q How does the single-stage impeller design benefit ventilation performance?The single-stage impeller design creates a streamlined airflow path with minimal turbulence and resistance. This results in stable, consistent airflow performance across varying load conditions, ensuring reliable mine ventilation at all times.
