Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Ask for use case, specification boundaries, supplier type, and RFQ preparation information for this product.
The diameter range is 200–800 mm, which should match the fan casing size. Always verify the exact diameter required for your specific fan model with the manufacturer or supplier.
The blade angle, typically 20–45°, influences airflow efficiency and pressure generation. A steeper angle can increase pressure but may reduce airflow, while a shallower angle may increase airflow but lower pressure. The optimal angle depends on the application requirements.
Common materials include aluminum alloy (e.g., AL6061-T6), stainless steel, engineering plastics, and carbon fiber composites. The choice depends on factors like operating temperature, corrosion resistance, and weight. Confirm material suitability with the manufacturer.
Airflow and static pressure are tested per ISO 5801. Balancing is done to grade G2.5 per ISO 1940-1. Surface treatment may follow MIL-A-8625 for anodizing. These standards serve as references; verify compliance with the supplier.
