Heat Protection
Extended Shaft: Separates the bearing assembly from the high-temperature gas path to reduce heat transfer.
Cooling Impeller: Dissipates heat around the shaft and bearing area during operation.
Air-Cooling Discs: Increase airflow around the exposed shaft section to reduce heat transfer toward the bearing housing.
External Bearing Arrangement: Positions the bearing assembly outside the hot gas path.
Heavy-Duty Construction
Reinforced Casing: 6–12 mm carbon or stainless steel plates with external structural reinforcement.
Impeller: Backward-curved or radial blades designed for the specified airflow and pressure.
Shaft: Forged 42CrMo alloy steel shaft with precision machining.
Rotor Assembly: Complete rotor dynamically balanced to ISO 1940 Grade G2.5 before assembly.

Quality Control
Material Inspection: Steel plates, shafts and major components are checked against specified material grades before fabrication.
Weld Inspection: Critical impeller welds are inspected by PT and UT.
Dimensional Inspection: Casing, impeller, shaft and mounting dimensions are checked against approved drawings.
Rotor Balancing: Complete rotor assemblies are dynamically balanced to ISO 1940 Grade G2.5.
Bearing Check: Bearing installation, lubrication and shaft alignment are inspected before trial operation.
Motor Test: Voltage, current, rotation direction and insulation are checked before shipment.
Running Test: Each assembled fan is run to check vibration, bearing temperature rise, motor current and airflow performance.
Test Documentation: Material certificates, NDT reports, balancing reports and factory test records are available for project orders.

FAQ
Q: Can the fan be supplied with a GA drawing for system integration?
A: Yes. GA drawings can be provided for checking fan dimensions, inlet and outlet positions, mounting arrangement and connection points before production.
Q: Can the fan be manufactured according to customer drawings?
A: Yes. Qiyue can manufacture the fan according to approved customer drawings and project specifications, including dimensional and connection requirements.
Q: Can the fan be supplied as part of a complete exhaust system?
A: Yes. The fan can be specified as part of an industrial exhaust system and matched with related ductwork and process equipment based on the project requirements.
Q: What information is included in the fan technical documentation?
A: Typical project documentation includes the fan datasheet, GA drawing, performance curve, material certificates, inspection records and factory test records.
Q: Can spare parts be ordered separately after the fan is delivered?
A: Yes. Replacement parts such as bearings, seals and wear components can be supplied separately for maintenance and service requirements.
Q: How is the fan prepared for overseas shipment?
A: The fan is prepared for export transportation with protective packaging suitable for handling, loading and long-distance shipment. Packaging can be arranged according to the shipping method and project requirements.
Q: Can the fan be supplied for replacement of an existing industrial exhaust fan?
A: Yes. Existing fan model information, drawings or installation dimensions can be used to match the replacement unit and maintain compatibility with the existing system.
Q: Can Qiyue provide technical support during installation and commissioning?
A: Yes. Technical information and installation-related documentation can be provided to support installation, connection and commissioning of the supplied fan.
