Application of Vacuum Technology

application of vacuum technology

Nowadays, vacuum technology has become indispensable in all industries. The application range of vacuum is extremely wide, mainly divided into low vacuum, medium vacuum, high vacuum and ultra-high vacuum applications.

Definition of vacuum technology
Vacuum technology is a technology that establishes an environment below atmospheric pressure in a container or space through mechanical, physical and other methods. The equipment used to extract air is called a vacuum pump. Its purpose is to change the state of matter or achieve a certain specific process requirement by reducing the gas pressure, such as vacuum packaging, electronic device manufacturing, etc.

Application of vacuum technology

1.Low vacuum application
Low vacuum is to use the pressure difference obtained by low vacuum to clamp, lift and transport materials, as well as dust removal and filtration, such as the vacuum cleaner used for home cleaning.

2.Medium vacuum application
Medium vacuum is generally used to remove gas or moisture absorbed in materials, manufacture light bulbs, vacuum metallurgy and as thermal insulation. For example, vacuum concentration can evaporate the moisture in dairy products without heating when producing condensed milk.

Vacuum metallurgy can protect active metals so that they will not oxidize during melting, casting and other processes. Vacuum steelmaking can prevent some added small amounts of elements from burning out at high temperatures and the infiltration of harmful gas impurities, which can improve the quality of steel.

3.High vacuum applications
High vacuum can be used for thermal insulation, electrical insulation, and to avoid collisions between electrons and ions. In high vacuum, the molecular free path is greater than the linear size of the container, so high vacuum can be used in electronic devices such as electron tubes, photoelectric tubes, and X-rays.

Combination of vacuum technology and screw rotors in air compressor manufacturing

Screw vacuum pumps are more reliable and have a longer service life
Equipped with variable speed drives and variable displacement vacuum pumps can optimize the energy required to operate at different vacuum levels and improve the working efficiency of air compressors. Airfler provides high-quality, stable and high-quality vacuum pumps.


Airfler's screw vacuum pumps are very quiet when working, creating a comfortable working environment.
