PP permanent magnet blower is an advanced ventilation equipment with the characteristics of high efficiency, energy saving and low noise. 

The following is an introduction to PP permanent magnet blowers:

  • Permanent magnet technology: PP permanent magnet blowers use permanent magnet synchronous motors as driving devices. Compared with traditional induction motors, permanent magnet motors have the characteristics of high efficiency and high reliability. The permanent magnet motor reduces energy loss and improves efficiency through direct driving of the magnetic field.

  • High efficiency: Due to the application of permanent magnet technology, PP permanent magnet blowers can provide greater air volume under the same power while maintaining efficient ventilation effects. This helps reduce energy consumption and lower running costs.

  • Energy saving: PP permanent magnet blowers have lower energy consumption than traditional blowers. It maintains efficient performance over long periods of time, reducing electricity bills.

  • Low noise: Permanent magnet blowers usually have low noise levels, which is very important for some applications that require a quiet environment, such as medical equipment, laboratories, etc.

  • Controllability: PP permanent magnet blowers can achieve precise control of the ventilation system by adjusting the speed or air volume of the motor to meet the needs of different applications.

  • Reliability: Due to the high reliability of permanent magnet motors, PP permanent magnet blowers usually have a long service life, reducing equipment maintenance costs.

  • Various applications: PP permanent magnet blowers are widely used in various applications, including air purification, industrial ventilation, medical equipment, heat exchangers, cooling systems, etc.


In short, the PP permanent magnet blower is an efficient, energy-saving, low-noise, and reliable ventilation equipment that is suitable for a variety of application scenarios, helping to improve system performance and reduce operating costs.

Working principle of permanent magnet blower

The permanent magnet blower is a kind of ventilation equipment, and its working principle involves key components such as permanent magnet motor, impeller and casing. Here is an overview of how a permanent magnet blower works:


  1. Permanent magnet motor: The permanent magnet blower uses a permanent magnet synchronous motor as the driving device. Permanent magnet motors contain strong magnetic permanent magnets that produce a constant magnetic field that keeps the motor synchronized while running.

  2. Impeller: In a permanent magnet blower, there are one or more impellers, usually helical, mounted on the motor shaft. When the permanent magnet motor starts and rotates, the impeller also starts to rotate.

  3. Suction and exhaust: There are suction and exhaust ports on the blower housing. The suction port sucks in air from the environment and introduces it into the interior of the blower. The exhaust port removes the treated air from the system.

  4. Working process: When the permanent magnet motor is started, its magnetic field rotates the impeller. As the impeller rotates, it draws and pushes air into the blower's internal space. This causes the air to increase in pressure inside the blower and then be expelled through the exhaust port.

  5. Air volume and pressure control: By adjusting the current of the permanent magnet motor, the air volume and pressure generated by the blower can be controlled. This control capability makes permanent magnet blowers suitable for a variety of applications and can meet different ventilation needs.


Generally speaking, the working principle of a permanent magnet blower is to use a permanent magnet motor to drive an impeller to rotate, thereby sucking in and discharging air to provide ventilation and increase airflow. This design is typically efficient, quiet, and reliable, making it suitable for a variety of industrial and commercial applications.

The difference between permanent magnet blower and ordinary blower

There are some key differences between permanent magnet blowers and ordinary blowers, mainly related to their working principle, performance characteristics and application fields. Here are the main differences between these two types of blowers:


Working principle:

  • Permanent magnet blower: The permanent magnet blower uses a permanent magnet synchronous motor as the driving device. This motor contains permanent magnets that generate a stable magnetic field to drive the impeller to rotate, thereby creating airflow. Permanent magnet motors typically run at a constant speed and therefore provide stable air volume and pressure.

  • Ordinary blowers: Ordinary blowers usually use induction motors, and their speed and power are usually unstable. The speed of ordinary blowers can be adjusted through frequency converters or other control methods to meet different ventilation needs.


Efficiency and energy saving:

  • Permanent magnet blowers: Permanent magnet blowers are generally more efficient because the permanent magnet motor loses almost no energy when running, which helps reduce energy consumption and save energy costs.

  • Regular Blower: Regular blowers may be less efficient in some situations because the induction motor may cause some energy loss.


Noise level:

  • Permanent magnet blowers: Permanent magnet blowers typically have low noise levels because permanent magnet motors generally operate more quietly than induction motors.

  • Regular Blower: The noise level of a regular blower can be higher and can be noisy especially when running at high speeds.


Control performance:

  • Permanent magnet blowers: Permanent magnet blowers generally have better control performance because the permanent magnet motor can control air volume and pressure more precisely.

  • Regular Blower: Regular blowers may require additional control equipment, such as frequency converters, to achieve similar performance where precise control is required.


Application areas:

  • Permanent magnet blowers: Due to their high efficiency, low noise, and reliability, permanent magnet blowers are often used in applications that require high-performance ventilation, such as medical equipment, laboratories, air purification systems, etc.

  • Ordinary blowers: Ordinary blowers are widely used in various ventilation and gas delivery fields, including industrial production, building ventilation and air conditioning systems.

To sum up, permanent magnet blowers usually have advantages in terms of efficiency, noise and control performance, and are suitable for some applications with higher performance requirements, while ordinary blowers are suitable for a wider range of ventilation and conveying needs.
