GD40 High-Temperature Axial Flow Fan is designed for industrial hot-air circulation, drying systems, furnace and kiln ventilation, heat-treatment equipment, and elevated-temperature process exhaust.
Its external motor and belt-driven arrangement is suitable for demanding thermal ventilation duties.
Fan configuration can be selected according to airflow, pressure, operating temperature, voltage, frequency, and installation requirements.
High-temperature axial fan with external motor and belt-driven arrangement for industrial hot-air circulation, drying systems, furnace and kiln ventilation, heat-treatment equipment and elevated-temperature process exhaust.
High-Temperature Axial Ventilation for Industrial Processes
GD40 is intended for industrial ventilation duties involving heated process air and elevated operating temperatures. Its axial-flow arrangement supports large-volume air movement through a compact cylindrical airflow path.
Typical duties include hot-air circulation, industrial drying, heat-treatment systems, furnace and kiln ventilation, and elevated-temperature exhaust. Final configuration should be reviewed against the actual airflow, pressure, gas temperature, operating duration and installation conditions.
Temperature Is a Selection Parameter
Normal operating temperature and maximum gas temperature should be provided before final fan selection. The allowable operating temperature depends on the selected fan construction and actual project conditions.
02 / Construction
External Motor & Belt-Driven Arrangement
The current GD40 configuration uses an external motor and belt-driven arrangement. The motor is positioned outside the primary airflow passage, while mechanical power is transmitted to the fan shaft through the drive system.

Axial Flow Casing
Straight-through airflow path for industrial ventilation.
02
External Motor
Motor positioned outside the primary airflow passage in the current configuration.
03
Belt Drive
Mechanical drive system connects the motor and fan shaft.
04
Industrial Installation
Designed for integration with industrial ducts and process ventilation systems.
05
Project Motor
Voltage, frequency and motor specification reviewed according to project requirements.

04 / Application Fit
Typical GD40 Applications
Industrial Drying
Drying ovens, chambers, production drying lines and heated-air circulation.
Process exhaust duties involving elevated gas temperature.
Process Air Circulation
Large-volume airflow for industrial processes involving heated air.
05 / Performance Selection
GD40 Performance Is Selected by Duty Point
GD40 performance depends on fan size, operating speed, blade configuration, drive ratio and selected motor. The final airflow and pressure combination should therefore be matched against the actual system operating point.
Airflow
Select against required process airflow.
Pressure
Match actual system resistance at the required airflow.
Fan Speed
Reviewed according to the required duty point and drive arrangement.
Motor
Selected after airflow, pressure, speed and project electrical conditions are confirmed.
Need the GD40 performance point?
Send the required airflow, pressure, gas temperature and electrical conditions for model and motor review.
06 / Before Selection
Information Required for GD40 Selection
01
Airflow
Required m³/h or CFM.
02
Pressure
Required static or total pressure.
03
Temperature
Normal and maximum gas temperature.
04
Medium
Gas composition, dust, humidity and corrosive components.
05
Installation
Fan orientation, duct layout and available installation space.
Send the existing fan nameplate, overall dimensions, inlet and outlet size, motor information, installation photos and any available duty data. These materials can be used as the starting point for engineering comparison.
GD40 is intended for hot-air circulation, industrial drying, heat treatment, furnace and kiln ventilation, and elevated-temperature process exhaust.
Is GD40 the same as a standard axial ventilation fan?
No. GD40 is positioned for applications where elevated operating temperature and drive arrangement must be considered during fan selection.
Why is the motor outside the airflow passage?
The current GD40 configuration uses an external motor and belt drive, separating the motor from the primary airflow passage.
What temperature can GD40 handle?
The allowable operating temperature depends on the selected construction and actual project conditions. Provide normal and maximum gas temperature before final selection.
Can voltage and frequency be supplied for overseas projects?
Motor selection can be reviewed according to the required voltage, frequency, phase and destination-market requirements.
