GD30K2-12 Axial Flow Fan
Belt-driven axial fan for industrial duct ventilation, factory air exchange, process air conveying and equipment-room exhaust.
Designed for pipeline installation with the motor mounted above the casing. Selection is based on airflow, pressure, duct size, blade quantity, blade angle, medium condition and installation layout.
Pipeline Axial Fan for Industrial Air Conveying
The GD30K2-12 axial flow fan is designed to form part of an industrial ventilation pipeline. Air moves through the cylindrical casing along the fan axis, making the series suitable for relatively large airflow, compact straight-through installation and low to moderate system pressure.
The motor is mounted above the fan casing. Power is transmitted through a V-belt arrangement, while the bearing box is positioned inside a protective cylinder. This structure keeps the motor outside the main straight-through air passage under suitable working conditions.
Standard selection is intended for air below 60°C under matching conditions. Corrosive, flammable or harmful gas service requires separate confirmation of gas composition, material, sealing, motor arrangement and electrical safety requirements.

GD30K2-12 Axial Flow Fan FAQ
What is the GD30K2-12 fan mainly used for?
It is mainly used for industrial duct ventilation, factory air exchange, process air conveying and equipment-room exhaust.
How is it different from a direct-drive axial fan?
The GD30K2-12 uses a belt-drive arrangement with the motor mounted above the casing, while a direct-drive axial fan mounts the impeller directly on the motor shaft.
Can it convey corrosive or flammable gas?
Only after separate review. Gas composition, material, sealing, motor arrangement and safety requirements must be confirmed before selection.
Are six-blade configurations available?
Yes. Four-blade and six-blade configurations are available, but the correct option should be confirmed from the required airflow and pressure point.
What information is needed for quotation?
Please provide airflow, pressure, duct size, medium, temperature, installation method, voltage, frequency, quantity and destination.
