Product Description
🛡️
Explosion-Proof Protection
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 (FAQ)
❓
What makes the FQ series fan explosion-proof?
The FQ series fan uses a pneumatic motor instead of an electric motor, which completely eliminates the risk of electrical sparks at the source. This design makes it inherently safe for use in underground mines, chemical plants, and other environments with high concentrations of flammable gases or explosive substances.
❓
What is the air volume range supported by the FQ series fans?
The FQ series fans support an air volume range of 50 to 800 m³/min, covering a wide range of ventilation requirements. Different models such as FQ№2.5 (20 m³/min) through FQ№6.7 (400 m³/min) and FQD№5.3 (300 m³/min) provide flexible options for various tunnel and underground ventilation scenarios.
❓
What is the recommended gas supply pressure for operating the FQ fans?
For most FQ series models, the recommended gas supply pressure is 0.3–0.5 MPa. The FQD№5.3 model requires a higher supply pressure of 0.5 MPa or above to achieve its rated performance of 3200 Pa total pressure at 2000 rpm.
❓
How much does maintenance cost compared to electric fans?
The FQ series pneumatic fans significantly reduce maintenance costs. Routine maintenance only requires replacing filter elements and inspecting the pneumatic motors — no professional electrician is needed. This reduces maintenance time by approximately 60% and spare parts costs by approximately 40% compared to conventional electric ventilation fans.
❓
What are the typical application scenarios for the FQ series fans?
The FQ series fans are widely used in coal mines, tunnels, chemical plants, and other confined underground spaces. They are especially suitable for short-distance ventilation of up to 200 meters, providing reliable airflow in environments where electrical equipment poses a safety risk.
❓
What is the noise level of the FQ series fans during operation?
The FQ series fans are designed for low-noise operation, with a noise level of ≤85 dB during normal working conditions. This ensures a safer and more comfortable working environment for personnel operating in tunnels, mines, and other confined spaces.
