Frequently Asked Questions (FAQ)
❓What types of fans are available in the FQ series and what are the key differences?
The FQ series includes models from FQ№2.5 to FQ№6.7 and the FQD№5.3. Standard FQ models operate at 1300 rpm with a gas supply pressure of 0.3–0.5 MPa, while the FQD№5.3 model operates at 2000 rpm and requires a gas supply pressure of 0.5 MPa or above, offering a significantly higher total pressure of 3200 Pa and greater air consumption, making it suitable for more demanding ventilation tasks.
❓What is the recommended gas supply pressure for these pneumatic fans?
For most FQ series models (FQ№2.5 through FQ№6.7), the recommended gas supply pressure is 0.3–0.5 MPa. For the FQD№5.3 model, a supply pressure of 0.5 MPa or above is required to achieve optimal performance and rated total pressure output.
❓Are these fans safe to use in coal mines and underground tunnels with flammable gas?
Yes. These fans are driven by pneumatic (air-powered) motors, which means there are no electrical components that could generate sparks. This makes them inherently safe for use in environments with flammable or explosive gases, such as coal mines and underground tunnels, where strict safety regulations apply.
❓What is the noise level of these pneumatic fans during operation?
The pneumatic motor is designed for smooth, quiet operation. The noise level is below 85 dB during normal operation, which helps improve working conditions for personnel in underground environments where prolonged exposure to high noise levels is a health and safety concern.
❓How easy is it to maintain and service these fans?
These fans feature a streamlined, modular design comprising four main components: the impeller, housing, pneumatic motor, and manifold. This straightforward structure makes disassembly, inspection, and replacement of parts simple and efficient, minimizing downtime even in challenging underground environments.
❓What applications are these pneumatic fans suitable for?
These fans are designed for a wide range of underground ventilation applications, including coal mines, road tunnels, railway tunnels, and other complex underground structures. Their flat pressure curve ensures stable airflow even under high-resistance conditions, making them ideal for long or branching tunnel ventilation systems where consistent performance is critical.
