❓ Frequently Asked Questions (FAQ)
QWhat are the main differences between the K40 and K45 series coal mine fans?
The K40 and K45 series differ primarily in their pressure performance. The K45 series delivers significantly higher total pressure (up to 2409 Pa) compared to the K40 series, making it more suitable for high-resistance ventilation networks. Both series are available in 4-pole, 6-pole, and 8-pole configurations to match different speed and airflow requirements.
QCan the FKZ coal mine fan operate in reverse ventilation mode?
Yes. The FKZ series fan supports convenient reverse wind operation. The reverse ventilation speed exceeds 60% of the forward speed, and there is no need to construct a separate reverse air duct, which significantly reduces installation costs and complexity.
QIs it possible to run multiple FKZ fans in parallel or in series?
Yes. Thanks to the flow stabilization device and the hump-free characteristic curve, the FKZ fan is well suited for combined operation with multiple fans. It can work stably under any resistance condition, making parallel or series configurations both safe and efficient.
QWhat safety certifications do the FKZ coal mine fans hold?
Each model in the K40 and K45 series holds the corresponding mine safety certificate (FKZ certification). For example, the K40-4 No.8 machine holds FKZ№8/5.5, and the K45-4 No.15 machine holds FKZ№15/200. These certifications confirm compliance with coal mine safety standards for underground ventilation equipment.
QHow is the motor connected to the impeller in the FKZ fan?
The motor is directly connected to the impeller (direct-drive design), which eliminates the need for a gearbox or belt drive. This design ensures excellent overall stability, simplifies installation, reduces maintenance requirements, and lowers the local resistance of the device.
QWhat is the maximum power and air volume available in the FKZ series?
In the K40 series, the maximum motor power is 250 kW (K40-8, No.26), with an air volume of up to 164.2 m³/s. In the K45 series, the maximum power is 250 kW (K45-6, No.20), with an air volume of up to 132.0 m³/s. These high-capacity models are designed for large-scale underground mine ventilation systems.
