Introduction
The Aluminum Alloy Axial Flow Fan Impeller is a key component widely used in industrial ventilation, air conditioning and cooling systems. Its main function is to transport air or gas in the axial direction through rotation, and is often used in air flow systems that require large flow and high efficiency.
Features
Excellent Corrosion Resistance
The naturally formed oxide film on the surface of aluminum alloy allows it to be corrosion-free for 500 hours in salt spray tests, which is 3 times more corrosion-resistant than ordinary carbon steel impellers.
Efficient Aerodynamic Performance
The precision-cast blades adopt NACA airfoil design, and the efficiency can reach 82%-88% in the air volume range of 1000-400000m³/h.
High-pressure Stable Operation
The hub structure of our products is optimized by finite element analysis to ensure that the vibration amplitude is less than 0.05mm when operating in the pressure range of 1000-25000Pa.
Precision Machining Process
The Aluminum Alloy Axial Flow Fan Impeller is manufactured by a five-axis CNC machining center, and the blade profile accuracy is controlled within ±0.1mm, and the dynamic balance residual is ≤1.0g·mm.
Applications
Industrial Ventilation System
The Aluminum Alloy Axial Flow Fan Impeller is widely used in the supply and exhaust air systems of factory workshops, machining areas, and storage spaces.
Cooling Towers and Heat Exchange Systems
In water-cooled or air-cooled towers, aluminum alloy impellers are widely used in cooling fan drive systems due to their good corrosion resistance and thermal conductivity.
Exhaust for High-rise Buildings and Underground Projects
Aluminum alloy impeller axial flow fans are often used in large-flow exhaust equipment in confined spaces such as subway tunnels, underground garages, and high-rise buildings.
Energy and Power Industry
In power plants, substations, and wind power equipment, aluminum alloy impellers are used in ventilation systems in closed spaces such as motor rooms and inverter cabinets.

Yonghecheng Fan Industry Co., Ltd. was established in Shenzhen in 1997, dedicated to the research and development of industrial centrifugal fans. Suzhou production plant was established in 2007, and Shenzhen factory was relocated to Suzhou in 2012. Fully optimize and upgrade production line equipment and manufacturing process in 2019. With more than 20 years of continuous improvement and development, we have become a professional fan manufacturer.
We have also obtained ISO 9001, GB--/T 45001-2020/ISO 45001:2018 CE certification, UL certification, invention patents, and utility model patents.
FAQ
Q: Has it passed relevant product certification?
A: ISO9001, CE and other certifications can be provided according to customer requirements to meet engineering projects or overseas procurement standards.
Q: Does it support centralized distribution or joint transportation?
A: It supports centralized packaging and transportation of multiple orders, reducing the number of handling times and logistics costs, and is suitable for corporate users who receive goods in a centralized manner.
Q: Does your company have after-sales service?
A: Of course! During the project design phase, we can provide professional fan technical support to match the fan with the best performance. During sales, we can provide fan drawings and performance curves, and adjust the plan according to customer needs. After sales, we will provide solutions within two hours after receiving the customer's after-sales call.
Q: What parameters should be considered when purchasing aluminum alloy axial flow fan impellers?
A: When selecting, you need to focus on air volume (m³/h), wind pressure (Pa), impeller diameter, number of blades and installation angle, and matching motor speed (RPM).
Q: How to determine whether the aluminum alloy impeller is suitable for outdoor or corrosive environments?
A: You should check whether the aluminum alloy used in the impeller has been anodized or anti-corrosion coated. If used in a humid, salty or slightly acidic or alkaline environment, it is recommended to choose a product with additional anti-corrosion technology.
Q: How should the impeller of an aluminum alloy axial flow fan be maintained on a daily basis?
A: Daily maintenance should include: regularly cleaning dust and oil stains on the blades, checking for deformation or cracks, and ensuring that there is no abnormal noise or vibration during operation; performing a dynamic balance test every 6 to 12 months; if used in a high temperature or high humidity environment, it is recommended to shorten the maintenance cycle. Proper maintenance can effectively extend the overall life of the impeller and fan system.
