Frequently Asked Questions (FAQ)
❓What is the operating pressure range for FQ series coal mine fans?
All FQ series models operate within a gas supply pressure range of 0.3~0.5 MPa, while the FQD№5.3 model requires 0.5 MPa or above for optimal performance.
❓What is the noise level of these pneumatic fans?
The pneumatic motor operates smoothly with a noise level below 85 dB, which significantly improves the working environment for underground personnel.
❓Which model is suitable for high-pressure ventilation applications?
The FQD№5.3 model is specifically designed for high-pressure applications, providing a total pressure of 3200 Pa with an air volume of 300 m³/min, making it ideal for complex and deep tunnel ventilation systems.
❓How easy is it to maintain these coal mine fans?
The fans feature a streamlined design composed of four main components: the impeller, housing, pneumatic motor, and manifold. This simplified structure makes routine inspection and maintenance straightforward, even in underground environments.
❓What are the main application scenarios for FQ series fans?
FQ series fans are widely used in coal mine tunnels, underground roadways, and complex road structures where effective gas removal and ventilation are critical. They are especially effective at eliminating gas accumulations in tunnel corners and dead-end areas.
❓What is the rotational speed of FQ series fans?
Most FQ series models operate at a standard speed of 1300 rpm, ensuring stable and consistent airflow. The FQD№5.3 model runs at a higher speed of 2000 rpm to meet demanding high-pressure ventilation requirements.
