In ventilation engineering, there has long been a trade-off: axial fans provide high airflow volume but low pressure, while centrifugal fans deliver high pressure but lower volume. But what if you need both? The answer lies in a highly advanced and efficient hybrid: the mixed flow fan.

As innovators in air movement technology, Hon&Guan has specialized in perfecting the mixed flow fan design. This technology is at the core of our industry-leading inline fans, delivering a superior balance of performance that is ideal for a vast range of applications. This article explores the unique advantages of this powerful fan type.

What Makes a Mixed Flow Fan Different?

A mixed flow fan combines design elements from both axial and centrifugal fans.

• Axial Fan: Air flows parallel to the fan's rotational axis (straight through).

• Centrifugal Fan: Air is drawn in axially and discharged radially, at a 90-degree angle.

• Mixed Flow Fan: Air is drawn in axially, but then discharged diagonally, at an angle between 0 and 90 degrees. The impeller blades are 3D-shaped to both push and sling the air.

This hybrid approach, combined with a special air-straightening stator vane, results in a fan that generates the high airflow of an axial fan while also producing enough pressure to overcome the resistance of long duct runs, bends, and filters—a feat neither of the other two can accomplish as efficiently.

The Key Advantages of Mixed Flow Technology

Choosing a mixed flow fan offers significant benefits, especially for ducted applications:

1. High Performance in a Compact Size: They can move a large volume of air (high CFM) against moderate static pressure, all within a compact, tube-like housing that fits easily into standard ductwork.

2. Exceptional Energy Efficiency: The aerodynamic design reduces turbulence and drag, allowing the fan to operate with less energy consumption compared to a centrifugal fan for the same duty point. This is especially true for models with modern EC motors.

3. Lower Noise Levels: The smooth, diagonal airflow path results in less air turbulence, which is a primary source of fan noise. This makes mixed flow fans significantly quieter than other fan types of similar performance.

4. Versatility: Their balanced performance makes them the ideal choice for most residential and light commercial ventilation systems, including bathroom and kitchen exhaust, HVAC boosting, and fresh air supply.

Ideal Applications for a Mixed Flow Fan

The mixed flow fan is the technology of choice for modern inline duct fans. You will find them used in:

• High-Performance Exhaust Systems: For bathrooms, kitchens, and utility rooms where you need to pull air through ducting and vent it outside effectively.

• HVAC Booster Fans: Perfect for adding to existing ductwork to improve the flow of heated and cooled air to rooms far from the central unit.

• Hydroponics & Indoor Grow Rooms: The combination of high airflow and moderate pressure is perfect for managing the environment in grow tents, where fans must pull air through carbon filters.

• Radon Mitigation Systems: Their reliability and efficiency make them an excellent choice for these critical, continuous-run safety systems.
