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
Airflow 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)
QWhat makes the FQ series fan explosion-proof?
The FQ series fan uses a pneumatic (air-powered) motor that completely eliminates the risk of electrical sparks at the source. This design makes it fully compliant with intrinsic safety standards, making it ideal for coal mines, tunnels, and chemical plants where flammable gases or explosive substances are present.
QWhat is the airflow range of the FQ series fan?
The FQ series covers an airflow range of 20 to 400 m³/min for standard models, with the high-pressure FQD№5.3 model reaching 300 m³/min at 3200 Pa. This wide range makes it suitable for various tunnel and underground ventilation requirements up to 200 meters in length.
QWhat gas supply pressure is required to operate the fan?
Most FQ series models require a gas supply pressure of 0.3–0.5 MPa. The high-pressure FQD№5.3 model requires a supply pressure of 0.5 MPa or above to achieve its rated performance of 3200 Pa total pressure.
QDoes maintenance require a professional 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 about 40% compared to conventional electric fans.
QWhat industries and environments is the FQ fan suitable for?
The FQ series is designed for use in coal mines, road and railway tunnels, underground construction sites, chemical plants, and other environments with high concentrations of gas or explosive substances. Its noise level of ≤85 dB also makes it suitable for noise-sensitive work environments.
QHow do I choose the right FQ fan model for my project?
Model selection depends on your required airflow volume, total pressure, and tunnel/space length. For short-distance ventilation (≤200 m) with moderate pressure needs, standard FQ models (e.g., FQ№5.6 or FQ№6.7) are recommended. For longer distances or higher pressure requirements, the FQD№5.3 with its 3200 Pa total pressure is the preferred choice. Please consult our technical team for a customized recommendation.
