Centrifugal fans are widely used in industrial and commercial ventilation systems due to their ability to generate high pressure airflow efficiently. They work by converting rotational energy from a motor to increase the velocity of air, which is then directed through ducts for ventilation or process needs.

Types and Features

Belt-Driven Centrifugal Fans

• These fans use a belt and pulley system to transfer power from the motor to the fan wheel.

• Belt drive allows flexible speed adjustment by changing pulley sizes, offering operational versatility.

• Belt drives enable motors to be mounted separately from the fan housing, reducing heat transfer and simplifying maintenance.
  

Double Inlet Design

• Double inlet fans have two symmetrical inlets that allow air to enter from both sides of the impeller.

• This design improves airflow efficiency and balance, reducing vibration and noise.

• It also enables a compact footprint while maintaining high performance.
  

Aerofoil Impellers

• Aerofoil-shaped blades are designed to minimize turbulence and drag while maximizing airflow and static pressure.

• These impellers offer improved aerodynamic efficiency compared to traditional blade shapes.

• Aerofoil impellers help reduce energy consumption and noise levels, enhancing overall system performance.
  

Typical Applications

• HVAC systems in commercial and industrial buildings

• Dust collection and filtration systems

• Process ventilation in manufacturing plants

• Cooling systems for machinery and electronic equipment

• Pneumatic conveying systems
  

Advantages of Belt-Driven Double Inlet Centrifugal Fans with Aerofoil Impellers

• High efficiency in moving air against resistance (static pressure)

• Adjustable speeds through belt and pulley modifications

• Reduced vibration and noise due to balanced airflow and aerodynamic blade design

• Ease of maintenance with accessible belt and motor components

• Durability suitable for heavy-duty and continuous operation environments
  

Centrifugal fans equipped with belt drives, double inlet design, and aerofoil impellers combine efficiency, flexibility, and reliability. They are essential components in ventilation and industrial air handling, delivering controlled airflow with reduced energy usage and noise. These fans are preferred in applications demanding robust performance and adaptability.
