An aerofoil bladed impeller is part of a centrifugal fan that is specifically designed to provide higher efficiency and minimal noise due to the function and profile of its curved aerofoil blades, which enhance its overall performance. They are suitable for clean air or low dust applications with a requirement of medium pressure, and can provide high volumes of uniform airflow with reduced power consumption.
Aerofoil impeller blades have a sharp leading edge, and a curved edge, which enables a higher lift to drag ratio as the air is separated above and below the blade. Aerofoil impeller blades achieve greater efficiencies compared to standard, constant thickness blades. Unlike straight blades that allow for no flow separation. The cross-section design of the blade and twist configuration are important when considering how to achieve the most efficient aerodynamic flow resulting in minimal losses. The smooth airflow achieved results in reduced turbulent velocity and ultimately lowers noise emissions.
Small changes in the blade profile can make a considerable difference to the performance and characteristics of the fan.
Computational fluid dynamics software is used to determine the optimal design of the fan. The profile and twist angle of the blades are thoroughly analysed to determine the most effective airflow angle of attack for achieving the highest efficiency.
Fan Ranges featuring Aerofoil Impellers:
The E-Wheel: Fibre Reinforced ABS – Plastic
Our
E-Wheel range features 7 aerofoil blades and is optimised for low to medium pressure applications. They are manufactured from a low weight, glass-fibre reinforced plastic. Available in sizes 315 - 560 mm.
The I-Wheel: Aluminium
Optimised for applications requiring high airflow, the aluminium
I-Wheel range features 5 aerofoil blades and an outlet diffuser. The aerofoil blades reduce noise, and the outlet diffuser increases efficiency. The special geometry of the wheel significantly reduces noise in comparison to the previous designs, while the improved geometry of the back plate allows for improved outflow. Available in sizes 450 - 630 mm.
Axial Fans: AKFD/AKFG
Our highly efficient range of axial fans feature sickle formed impellers made of cast aluminium. The optimised blade design improves the acoustic performance resulting in very low noise emissions. They offer continuous speed control and fast start up due to the pre-configured system and can provide flow rates up to 32,000 m³/h. Our AKFD and AKFG ranges are available in sizes 500 - 1000 mm and can be installed in any position.
