What is a Mixed Flow Fan

Aosun’s mixed flow fan combines the strengths of both axial and centrifugal fans, giving you a highly efficient ventilation solution. The airflow path sits between straight and curved, allowing you to benefit from large volumes of air and higher pressure. This makes it ideal for long ducts or complex ventilation systems.
Meanwhile, with an optimized impeller design, the fan runs smoothly, uses less energy, and produces very little noise. It also takes up less space, which makes installation easier.
Advantages of Mixed Flow Fans

Impressive Airflow and Static Pressure
Have you ever struggled with a fan that can’t push enough air or doesn’t deliver the pressure needed to reach the right spot? With our mixed flow fan, that’s no longer a concern. Its unique design allows steady airflow even in long ducts with high resistance, without the common drop in volume.
Aosun’s unit delivers up to 180,000 CFM and generates as much as 10 inches of static pressure. That means smoother circulation, a healthier environment, and stable conditions for your equipment. You also decrease wasted energy and unnecessary maintenance caused by weak airflow.
Lower Noise and Energy Consumption
Noise and high power bills are common headaches. Our mixed flow fan solves both with refined blades and an optimized air path that minimizes turbulence and friction. The result is quiet operation, even during long shifts, with none of the disruptive hum of older fans.
After that, at the same output, a mixed flow fan uses about 30% less power than a centrifugal fan, helping you slash electricity costs. Over time, those savings add up, giving you real value beyond the purchase price.
Excellent Corrosion Resistance
When your fans have to work in humidity, chemicals, salt air, or heavy dust, corrosion can quickly turn into downtime. Poor resistance will cause frequent breakdowns and rising service bills. Our mixed flow fan is built differently. High-grade alloys and protective coatings keep it safe from moisture, acids, and salts. That durability ensures steady performance in tough environments, reduces replacement cycles, and keeps your operation running without interruptions.
Adaptable for Narrow Places
Tight spaces are a constant challenge—underground ducts, ceiling voids, or small equipment rooms often make installation a nightmare. As a mixed flow fan supplier, we design compact and streamlined build that fits easily where other fans fail. You don’t need to tear out existing ductwork or budget for costly modifications. Despite the smaller footprint, you still get powerful airflow and pressure. It saves space, time, and money while keeping efficiency high.
Easy to Customize
Every project has unique demands. You may need a certain airflow, a special motor, high-temperature materials, or even explosion-proof protection. Standard fans rarely fit all these requirements, forcing you to compromise. Our mixed flow extractor fan changes that.
We offer full customization, including size, blade material, corrosion grade, noise control, and more, so your system works exactly the way you need it to. No wasted investment, no mismatched equipment, only a reliable solution tailored for your operation.
Cost-Effective
A mixed flow inline fan doesn’t just balance airflow, pressure, noise, and efficiency. It also gives you a clear cost edge over centrifugal models. What matters even more is its long service life, reduced maintenance, and lower energy consumption.
Buying one is essentially an effective investment that keeps paying off for years. Unlike regular fans that need constant repairs, replacements, or waste power, this mixed flow fan helps you cut your total cost of ownership. It’s the right choice if you’re aiming for long-term stability and value.
Applications of Mixed-Flow Inline Fans

Aerospace
Overheating in aerospace electronics will contribute to component failures, shorten service life, and compromise performance. A mixed flow fan addresses this issue efficiently. It delivers both strong airflow and high static pressure, even in tight cabin spaces where other fans often fail.
Furthermore, it also performs steadily in high-altitude, low-pressure conditions while keeping noise to a minimum, reducing crew discomfort. When made with lightweight materials, it helps cut total aircraft weight, lowers energy use, and trims maintenance costs.
Military
Mixed flow inline fans are widely used in military vehicles, bases, and defense systems. Compared to standard fans, they offer stronger resistance to corrosion and impact, which is critical in deserts, humid areas, or salty coastal zones.
Besides, their compact and durable design makes them a reliable choice for engines and other heavy-duty systems. More importantly, they can be tailored to your needs—airflow, pressure, and size can all be adjusted to ensure maximum reliability in mission-critical applications.
Residence
Compared to axial fans, a mixed flow fan runs quieter, consumes less power, and still delivers ample airflow. It is very suitable for high-rise buildings, underground garages, and complex duct networks. Thanks to its compact shape, it fits easily into tight ceiling or duct spaces without losing performance. If you want cleaner air, steady ventilation, and better comfort for residents, this fan combines efficiency with cost-effectiveness, making it a smart investment for you.
Agriculture
Poor air circulation restricts crop growth, makes climate control harder, and raises health risks for livestock. A mixed flow fan handles these challenges with high airflow and stable pressure, ensuring even ventilation in greenhouses and creating a healthier environment for crops.
For instance, during the storage of produce, mixed flow fans can maintain storage areas fresh to prevent mold and spoilage. On the other hand, in livestock farms, it helps remove harmful gases such as ammonia and CO₂, reducing disease risks and boosting output.
Yes, they can. You just need the right protection for them. A rain cover or an extra housing can be used to keep the motor and internal parts safe from moisture and dust. When installing, make sure there’s a slight tilt to prevent water from pooling. If your site has high humidity or corrosive gases, go for a model with strong waterproofing or a corrosion-resistant coating.
Typical options include carbon steel, stainless steel, aluminum alloy, and galvanized sheet.
Carbon steel offers strength and is commonly used in industrial applications. Stainless steel has excellent corrosion resistance, making it ideal for chemical plants or coastal areas. Aluminum alloy is lightweight, which makes installation and handling easier. Galvanized sheet is a cost-effective choice.
You should consider airflow, pressure, available space, and the use environment. First, define the ventilation volume and duct resistance, since they determine the airflow and pressure range. Then, check your installation space to ensure the fan matches.
Furthermore, think about operating conditions, such as humidity, high temperature, or corrosive gases. And pick a fan with the right motor protection and casing material. The safest way is to consult an engineer to review your setup before finalizing the model.
Mixed flow inline fans are usually quieter than axial fans because they can generate the same pressure at lower speeds. Besides,the blade design is also an important factor in reducing noise. the sound produced by rear curved blades is usually smaller than that of front curved or straight blades. The installation environment can also affect the noise.
The service life of mixed flow inline fans can last to 10 years.
Its durable structural design enable this type of fan to operate stably for a long time. In addition, if regularly maintained and used correctly as required, its service life may be further extended.
Always cut the power first. Then open the casing and wipe the blades with a soft brush or cloth to remove dust and grease. For stubborn dirt, use a mild detergent, rinse with clean water, and avoid harsh chemicals. After that, make sure the impeller is dry before reassembly. You had better clean it every six months to prevent dust accumulation.

Yes,but it depends on motor type and control module configuration.If you need the function,you should choose EC brushless motor,which comes with the speed control interface to access the control system.And the control protocol must be compatible with the smart home/IoT platform.Additionally,you should pay attention to the protection level of the control module;it is recommended to select modules with IP54 or higher protection to avoid electrical failures.
When you select the mixed inline fans,you need to pay attention to the wind pressure and air volume parameters.Ensure the parameters are matched with the duct length and resistance.
And the impeller should choose die-cast aluminum alloy or stainless steel as the material,which has high rigidity and corrosion resistance.
The motor can select the EC brushless motor with high energy efficiency and low noise,supporting intelligent control.
As for the level of protection,if just for standard use,an IP44 rating is sufficient.However,if you need to use the fan in humid environments,upgrading to IP54 or higher is recommended.
Besides,you should confirm the fan’s external dimensions and installation interface specifications to select the appropriate fan.
Compared to axial fans, mixed flow technology enhances pressure handling capacity through optimized airflow patterns and impeller design. Mixed flow fans employ an impeller structure combining axial and centrifugal design, using a helical motion to propel air and generate stable, moderate pressure. In contrast, axial fans can only provide low-pressure straight-line axial flow.
