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)
Q
What makes FQ series fans explosion-proof and suitable for underground mines?
The FQ series fans are driven by pneumatic (air-powered) motors, which completely eliminate electrical sparks at the source. This makes them inherently safe for use in underground coal mines, chemical plants, and other environments with high concentrations of flammable gases or explosive substances.
Q
What is the air volume range supported by FQ series fans?
The FQ series fans support an air volume range of 50–800 m³/min, covering a wide range of ventilation requirements from small tunnels to larger underground workspaces. Specific models such as FQ№2.5 start at 20 m³/min, while larger models like FQ№6.7 can reach 400 m³/min.
Q
What is the recommended gas supply pressure for operating the FQ fans?
Most FQ series models operate at a gas supply pressure of 0.3–0.5 MPa. The high-performance model FQD№5.3 requires a supply pressure above 0.5 MPa to achieve its rated total pressure of 3200 Pa.
Q
Does maintenance of FQ fans require professional electricians?
No. Because FQ fans use pneumatic motors instead of electric motors, routine maintenance only involves replacing filter elements and inspecting the pneumatic motor components. This reduces maintenance time by approximately 60% and spare parts costs by 40%, and can be performed by general maintenance personnel.
Q
What are the typical application scenarios for FQ series fans?
FQ series fans are widely used in underground coal mine tunnels, chemical plant workshops, confined construction spaces, and other short-distance ventilation scenarios (≤200 m). They are especially recommended wherever electrical equipment poses a safety risk due to flammable or explosive atmospheres.
Q
What is the noise level of FQ series fans during operation?
The FQ series fans are designed with noise control in mind. During normal operation, the noise level is kept at ≤85 dB, which meets occupational health and safety standards for underground and industrial working environments.
