Frequently Asked Questions
Yes. The fan should be selected based on the project’s airflow requirements, system resistance, fan diameter or installation opening, and the selected series. Final performance is subject to the model specifications confirmed by Haitong.
Axial fans are generally suitable for general ventilation, exhaust, and straight-through air transport. When duct system resistance is high or greater pressure capability is required, other designs, such as centrifugal fans, should also be evaluated. The final selection should be based on the actual airflow, pressure, installation space, and operating requirements.
We can assess this based on the project's power supply conditions. However, 50 Hz and 60 Hz affect motor speed, airflow, pressure, and power, so the selection must be reviewed again for the required frequency.
The duct connection can be configured according to the model and project layout. If connecting a duct, provide the duct dimensions and system resistance so that the fan's pressure capacity and installation method can be confirmed.
It can be assessed based on the current product range and project requirements. Haitong’s existing product information includes the Square Wall-Mounted Axial Fan and Sidewall Exhaust Fan product lines. Specific dimensions, louvers, protective screens, and mounting methods should be confirmed before production.
This can be assessed based on the fan structure and installation location. Protective mesh, louvers, and other accessories affect the installation dimensions and system resistance. The final configuration should be confirmed together with the fan selection.
This should not be stated as a default. Fire smoke exhaust applications require the selection of a dedicated high-temperature smoke exhaust fan, suitable temperature-resistance requirements, and any testing or certification documents required for the project. A standard axial fan’s website page should not directly claim fire smoke exhaust performance.
The appropriate construction, materials, motor, and surface treatment can be evaluated based on the medium temperature, dust conditions, corrosiveness, and project specifications. However, ordinary axial fans should not be universally described as high-temperature, explosion-proof, or corrosion-resistant products.
Please provide the model, airflow, total/static pressure, installation orientation, air inlet and outlet configuration, material, insulation, motor voltage/frequency, control method, filter module, smoke control and fire protection requirements, quantity, and packaging requirements. Performance, dimensions, and certification information are subject to the confirmed product and order documents.
