▶ Product Video
✎ Product Description
🔥 Explosion-Proof
Eliminates the risk of electrical sparks at the source. Suitable for underground/chemical environments with high concentrations of gas, flammable and explosive substances. The preferred choice for "intrinsically safe" ventilation equipment.
🔧 Easy Maintenance
Routine maintenance does not require professional electricians. Only filter element replacement and pneumatic motor inspection are needed — reducing maintenance time by 60% and spare parts costs by 40%.
📈 High Performance
Air volume range 50–800 m³/min. Suitable for tunnel/short-distance ventilation (≤200 m) with adjustable air pressure. Noise level ≤85 dB.

❓ Frequently Asked Questions
Q What makes the FQ pneumatic fan explosion-proof?
The FQ series fan uses a pneumatic (air-driven) motor instead of an electric motor, which completely eliminates the risk of electrical sparks. This design makes it inherently safe for use in coal mines, tunnels, and chemical facilities where flammable gases or explosive dust may be present.
Q What is the air volume range of the FQ fan series?
The FQ series covers an air volume range of 50–800 m³/min, with specific models ranging from 20 m³/min (FQ№2.5) up to 400 m³/min (FQ№6.7), making it suitable for various tunnel sizes and ventilation requirements.
Q What gas supply pressure is required to operate the FQ fan?
Most FQ models operate at a gas supply pressure of 0.3–0.5 MPa. The high-pressure model FQD№5.3 requires a supply pressure above 0.5 MPa to achieve its rated performance of 3200 Pa total pressure.
Q Does maintenance of the FQ fan require a certified electrician?
No. Because the fan is pneumatically driven, routine maintenance only involves replacing filter elements and inspecting the pneumatic motor. This reduces maintenance time by approximately 60% and spare parts costs by 40% compared to electric fan systems.
Q What is the maximum ventilation distance supported by the FQ fan?
The FQ fan series is designed for short-distance ventilation applications up to 200 meters (≤200 m), making it ideal for tunnel headings, underground roadways, and confined industrial spaces.
Q What is the noise level of the FQ pneumatic fan during operation?
The FQ series fans are engineered to operate at a noise level of ≤85 dB, ensuring compliance with occupational health and safety standards in underground mining and industrial environments.
