Product Description
💨
Pneumatic System
Equipped with optimized three-dimensional blades with an aerodynamic profile (made of 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 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 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 rating 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
❓ What explosion-proof certification does this coal mine fan have?
The fan is equipped with an explosion-proof motor of ExdI Mb class, which meets the requirements for use in underground coal mines with methane and coal dust explosion hazards. The motor chamber is hermetically sealed from the air duct to prevent spark leakage.
❓ What is the operating temperature range of the fan?
The fan is designed for operation in a temperature range from -20°C to +40°C, making it suitable for the harsh environmental conditions of underground coal mines.
❓ What material are the fan blades made of?
The blades are manufactured from forged aluminum alloy with an optimized three-dimensional aerodynamic profile. This ensures minimal aerodynamic losses and consistently high efficiency under various operating conditions.
❓ What is the motor protection rating of this fan?
The motor has an IP55 protection rating and insulation class F, providing reliable protection against moisture, dust and corrosion in underground mining environments.
❓ What type of drive does the fan use?
The fan uses a direct-drive design — the motor is directly connected to the impeller without intermediate components such as long shafts or pulleys. This provides 99% transmission efficiency, reduces the number of potential failure points and increases overall operational reliability.
❓ In what applications can this fan be used?
The fan is designed primarily for ventilation of underground coal mines. Thanks to its explosion-proof design, high protection rating and wide operating temperature range, it can also be used in other industrial facilities with increased requirements for explosion and dust protection.
