The FBD-10.0 Coal Mine Explosion-Proof Press-in Axial Flow Fan is a high-performance, flameproof counter-rotating axial flow local ventilator designed specifically for underground mining environments. As part of the advanced FBD series, this fan integrates two counter-rotating impellers driven directly by two explosion-proof motors, delivering superior airflow with exceptional energy efficiency.
The model designation “FBD-10.0” carries specific meaning: F stands for local fan, B represents explosion-proof type, and D indicates counter-rotating design. The No.10.0 refers to the nominal impeller diameter in decimeters (1,000 mm), while the suffix (e.g., 2×30 or 2×55) denotes dual motors and their respective power ratings in kilowatts.
Engineered with internationally leading three-dimensional twisted, swept, and orthogonal combination blades, this fan ensures stable airflow, minimal vibration, and high operational efficiency. The FBD series has also obtained a national patent for its side air inlet noise reduction and silencing device (Patent Certificate No. 2583510), representing a major breakthrough in mine ventilation technology.
The FBD-10.0 explosion-proof axial flow fan is widely deployed across various demanding industrial sectors:
Underground coal mines – For local ventilation in coal mining faces, tunneling operations, and shaft construction in environments containing gas, coal dust, or other explosive gases
Metal and chemical mines – Suitable for mine excavation, local ventilation, and long-distance tunnel ventilation in metal and chemical mining operations
Tunnel construction – Ideal for long-distance ventilation during tunnel boring and underground infrastructure projects
Metallurgical and chemical industries – Applicable for ventilation in high-pressure industrial ventilation scenarios
The fan can be used both as a complete unit or in staged configurations depending on ventilation resistance requirements, significantly reducing energy consumption and ventilation time. It serves as an ideal local ventilation solution for coal mine underground operations, mining faces, and various chamber ventilation applications.
The FBD-10.0 fan is engineered to withstand harsh underground conditions and complies with rigorous safety standards:
| Environmental Parameter | Specification |
|---|---|
| Operating Temperature | -20℃ to +40℃ |
| Altitude | Not exceeding 1,000m |
| Relative Humidity | ≤95% ±3% (at 25℃) |
| Dust Concentration | ≤200 mg/m³ (for gas passing through) |
| Rated Frequency | 50Hz |
| Supply Voltage | 380V/660V or 660V/1140V |
Important installation notes: The fan can be placed directly on the tunnel floor or suspended on the tunnel wall. When installed on the floor, the suction port (collector end) must not be immersed in water or mud. It must be installed in intake airflow where gas concentration is below 1%; if gas concentration exceeds 1%, power must be cut off immediately.
The FBD-10.0 fan incorporates multiple advanced features that set it apart from conventional ventilation equipment:
The blades are designed using three-dimensional fluid dynamics with an airfoil-twisted profile, creating a broad high-efficiency operating zone. The counter-rotating direct-coupled transmission eliminates the need for guide vane devices, increasing pressure while streamlining airflow direction. The fan consistently operates within its optimal efficiency range under various working conditions.
The fan incorporates a double-layer silencing structure lined with ultra-fine glass wool and perforated plates inside the collector, both stages of the fan body, and the diffuser. The counter-rotating design reduces friction noise, while the outer casing features a composite soundproofing装置. Overall operating noise is controlled below 85 dB(A), with specific A-weighted sound levels below 35 dB, dramatically improving the underground working environment.
The fan delivers a relatively flat pressure curve with minimal surge phenomenon, ensuring stable operation even in high-pressure, low-flow scenarios. This stability enables long-distance air supply underground and strong adaptability to complex tunnel geometries.
Advanced thermal spraying technology (supersonic arc spraying and high-velocity flame spraying) is applied to the casing and blades. Based on corrosion elements present in the mine, over 20 different coating materials can be formulated, ensuring the blades resist rust, wear, and corrosion for an extended service life.
The FBD-10.0 can deliver normal air supply for tunnel lengths up to 2,000 meters without requiring fan relocation, significantly reducing labor intensity and ventilation time for underground workers.
Depending on different ventilation resistance requirements, the fan can be used as a complete unit or operated in staged modes, reducing ventilation power consumption and conserving energy.
The fan is manufactured in compliance with enterprise standard Q/DF001-2011 and industry standard MT222-2007, ensuring consistent quality and reliability. Performance curves are tested according to GB/T1236-2000 (the national standard for fan aerodynamic performance testing methods) under standard conditions (gas temperature t=20℃, density ρ=1.2 kg/m³, atmospheric pressure ρ=101,325 Pa).

Note: Performance data may vary slightly between manufacturers. Please refer to specific product datasheets for exact specifications.
Proper maintenance ensures long-term reliability and safety:
Routine inspection: Every 6 months of operation, check the tightness of bolts and nuts on all connecting components, and inspect blades and other parts for cracks or weld failures
Emergency shutdown triggers: Immediate stop if the fan or motor experiences sudden severe vibration, or if motor temperature or current suddenly rises beyond rated values
Safety reminder: No personnel should stand near the diffuser outlet during fan startup or operation
Spare parts: When replacing motor components, use products from the same motor manufacturer
The fan has received explosion-proof certification and carries the official “MA” safety mark, with supporting motors also being explosion-proof safety products.
The FBD-10.0 Coal Mine Explosion-Proof Press-in Axial Flow Fan represents a state-of-the-art ventilation solution that combines high efficiency, ultra-low noise, robust durability, and exceptional safety features. Whether for coal mining, metal mining, tunnel construction, or industrial ventilation applications, this fan delivers reliable, energy-saving performance in even the most challenging hazardous environments.
