What is the difference between a blower fan and a regular fan?

• The difference between blower and fan
• Blowers and fans are similar in appearance, but the way they generate wind is different. A blower drives an impeller to generate airflow through the rotation of a motor, while a fan blows air through the rotation of blades.
• Applicable scenarios for blowers and fans
• The air volume of the blower is large, but the noise is also large. It is suitable for scenes that require large air volume, such as factories, ships, and other large space scenes, but it is not suitable for home use. Fans are lighter and less noisy, and are suitable for use in small-area scenarios such as homes and offices.
• Advantages and disadvantages of blowers and fans
• The advantages and disadvantages of the two are relatively obvious. Although the blower has a large air volume, it is noisy and large in size, making it inconvenient to carry. The fan is small and portable, but the air volume is relatively small, making it suitable for use in a comfortable environment. In actual use, the choice should be based on actual needs.

Root blowers is a positive displacement blower. Its working principle is based on the relative movement of two blade-shaped rotors in the cylinder to compress and transport gas.
This kind of fan has a simple structure and is easy to manufacture. It is suitable for gas transportation and pressurization systems in low-pressure situations, and can also be used as a vacuum pump.
The design and structure of the Roots blower ensure that it can effectively increase the pressure and flow of gas, and at the same time achieve precise control of gas flow and pressure by adjusting the rotation speed and angle of the impeller.
This type of pump is popular for its unique operating mechanism and wide range of applications, especially where stable air flow and pressure are required.

Root blower working principle

• The working principle of Root blowers can be simply summarized into the following steps:
• Suction stage: When the rotor rotates, the volume of the chamber gradually increases, forming a low-pressure area.This low-pressure area attracts outside air into the chamber.
• Compression stage: As the rotor continues to rotate, the volume of the chamber gradually decreases.This process causes the air to become compressed, increasing its pressure.
• Exhaust stage: When the volume of the chamber reaches the minimum value, the compressed air will be discharged from the chamber.At this time, the rotation of the rotor will increase the volume of the chamber again to prepare for the next round of suction.
• By repeating the above steps, the Roots blower can continuously suck in, compress and discharge air.This working principle enables Roots blowers to produce high-pressure, high-flow airflow.

Roots blower is a positive displacement blower. Its working principle mainly relies on the relative movement of two blade-shaped rotors (usually three-bladed impellers) in the cylinder to compress and transport gas. The specific process is as follows:

The working principle of Roots blower

• Impeller rotation: When the motor drives one of the impellers to rotate, the other impeller will rotate synchronously at the same speed and in the opposite direction through the action of the synchronization gear.
• Gas suction and compression: Since the gaps between the impeller and the impeller, the impeller and the casing, and the impeller and the wall panel are extremely small, a vacuum state is formed at the air inlet during the rotation of the impeller, and the air is sucked into the intake air under the action of atmospheric pressure cavity. As the impeller continues to rotate, two of the blades of each impeller, the wall panel and the casing form a sealed cavity, and the air in the intake cavity is continuously brought to the exhaust cavity by the sealed cavity formed by these two blades. And because the impellers in the exhaust chamber mesh with each other, the air between the two blades is squeezed out.
• Gas discharge: After continuous inhalation and squeezing, air is continuously transported from the air inlet to the air outlet, completing the entire gas transportation process.

• Low pressure range‌: The pressure is lower than 58.8kpa, including 9.8kpa to 58.8kpa.This type of fan usually uses air cooling, and is mostly designed with a single oil tank.
• ‌Medium pressure range‌: The pressure is between 58.8kpa and 98kpa.This type of fan requires water cooling, and most of them are designed with double oil tanks.
• ‌High pressure range‌: When the pressure exceeds 98kpa, especially when it exceeds 140kpa, double-stage pressure boosting technology is required to ensure stable operation of the fan under high pressure.
