Product Video
Product Description
Pneumatic System: Equipped with optimized three-dimensional blades with aerodynamic profile (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, making it suitable for use in methane and coal dust explosion hazard environments in coal mines.
Transmission Design: Direct connection between 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 degree 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 explosion-proof certification does this coal mine fan have?
The fan is equipped with an explosion-proof motor certified to ExdI Mb class, specifically designed for use in underground coal mines where methane gas and coal dust create explosion hazards. The motor chamber is hermetically sealed from the air duct to prevent any spark leakage.
Q
What material are the fan blades made of?
The fan blades are manufactured from forged aluminum alloy, shaped with an optimized three-dimensional aerodynamic profile. This material choice ensures both high strength and minimal weight, contributing to reduced aerodynamic losses and long-term operational stability.
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 well-suited for the harsh and variable environmental conditions found in underground coal mines.
Q
What is the motor's protection rating and insulation class?
The motor features an IP55 protection rating, which provides complete protection against dust ingress and resistance to water jets from any direction. The insulation class is F, allowing the motor to handle higher operating temperatures and ensuring durability in humid and dusty underground environments.
Q
How does the direct-drive transmission improve reliability?
By directly connecting the motor shaft to the impeller, the design eliminates intermediate components such as long shafts, belts, and pulleys. This achieves a 99% transmission efficiency, significantly reduces the number of potential failure points, and minimizes maintenance requirements compared to traditional belt-driven fan systems.
Q
Is this fan suitable for both main and auxiliary ventilation in coal mines?
Yes, the fan's robust explosion-proof design, stable aerodynamic performance, and wide operating temperature range make it suitable for various ventilation applications in coal mines, including both primary mine ventilation and auxiliary local ventilation systems in tunneling and extraction areas.
