Introduction to Direct-Drive Centrifugal Fan

A direct-drive centrifugal fan is a type of fan in which the impeller is mounted directly onto the motor shaft, without the use of an auxiliary drive system such as a gearbox or belt.

Applications of Direct-Drive Centrifugal Fans

Direct-drive centrifugal fans are used in a wide range of applications thanks to their high efficiency and operational stability. Common applications include:

• Industrial ventilation systems

• Central ventilation systems

• Fire escape stairwell pressurization systems

• Air conditioning systems

• Dust extraction and smoke filtration systems

They are also used in various industries such as food processing, wood processing, cement, and steel manufacturing.

Advantages and Disadvantages of Direct-Drive Fans

Advantages:

• High efficiency

• Low noise level

• Durable and low maintenance

• Compact size

• Stable airflow and pressure

• Extremely high performance

Disadvantages:

• Power limitation
• Inability to adjust speed

Classification of Direct-Drive Centrifugal Fans

Most centrifugal fans are classified into three main types based on the pressure levels they can generate. Below are the descriptions and corresponding pressure ranges for each type:

• Low-Pressure Centrifugal Fan: Pressure range from 50 Pa to 500 Pa.

• Medium-Pressure Centrifugal Fan: Pressure range from 500 Pa to 2500 Pa.

• High-Pressure Centrifugal Fan: Pressure above 2500 Pa.

Note: The above pressure ranges are approximate values and may vary depending on the manufacturer.
