What is the difference between Roots blower and air pump?

What is the difference between Roots blower and air pump? The main differences are working principle, pressure range, application field, working characteristics, etc. Xinqianshun will prepare the following detailed introduction for you.

Roots Blower and Air Pump are two kinds of equipment used in gas transmission and pressurization. Although they are similar in some aspects, they also have obvious differences. The following are the main differences between them:

working principle:

Roots blower: Roots blower works based on the centrifugal principle. The centrifugal force is generated by the rotation of the impeller. The gas is sucked in from the inlet, compressed and discharged to the outlet. It is mainly used for positive pressure transmission of generated gas, such as wastewater treatment, dust collection, etc.

Air pump: The air pump usually works based on the volume principle, and inhales and discharges gas through volume change. Air pumps are usually used to generate low pressure or vacuum for various applications, such as laboratory operation, vacuum packaging, etc.

Pressure range:

Roots blower: Roots blower is usually applicable to higher gas pressure range and can generate higher positive pressure. They are often used in industrial applications that need to transport gas or increase gas pressure.

Air pump: The air pump is usually applicable to the lower gas pressure range, and its main function is to generate vacuum or slight positive pressure for adsorption, exhaust and other low-pressure applications.

Application field:

Roots blower: Roots blower is usually widely used in sewage treatment, water treatment, dust collection, food processing and other fields, where higher gas pressure and flow are required.

Air pump: Air pump is mainly used in laboratories, medical equipment, food packaging, vacuum freezing and other fields, where vacuum or slight positive pressure is required.

Working characteristics:

Roots blower: the airflow of Roots blower is relatively stable and is not prone to pulsation, which is suitable for scenarios where stable gas transmission is required.

Air pump: The air flow of the air pump is usually unstable and may have pulsations. This is acceptable in some applications, but may not be appropriate in situations where steady airflow is required.

In conclusion, there are obvious differences between Roots blower and air pump in working principle, pressure range, application field and working characteristics. The selection of appropriate equipment depends on the specific application requirements, including the required gas pressure, flow and operating characteristics of the equipment.

Finally, I will teach you a way to quickly select fans with computers and mobile phones. You can go to the Xinqianshun website, click the fan selection on the navigation bar, enter the selection page, enter the air volume, select the air pressure, and inquire about the price, model, power, speed, weight and other detailed parameters of the fan you need.
