Vaccum Pumps Technology & Application

Vacuum technology provides efficient production in many industries. It is integral in drying, degassing of oils, vacuum distilling, molecular evaporation, and desorption of gas from surfaces to extend the life of devices, all with enhanced heat absorption.

Vacuum technology refers to any processes operating in gas conditions significantly lower than atmospheric pressure, namely below the threshold of -700 mbar (negative pressure) – equivalent to a value of 300 mbar absolute.

At AERZEN, we have been providing custom vacuum technology and fabrication solutions to companies worldwide since the 1940s. We offer industrial vacuum systems such as vacuum pumps and motor blowers that are crucial to the creation, maintenance, and measurement of partial and full vacuum states.

We are committed to giving our customers cost-effective vacuum technology via heavy-duty vacuum pumps that combine power, durability, and modularity for multiple applications.

Types of Vacuum Technology and Their Industry Applications

AERZEN provides multiple solutions to the particular requirements of industrial vacuum and high vacuum technology

There are several types of vacuum pump and blower systems available, and choosing the right equipment is incredibly important to enable you to build, maintain, and improve your industrial vacuum systems. These types of technologies are industry-specific; for instance, vacuum pump blowers for the steel industry may not be suitable in the aeronautical space.

A vacuum exists in five pressure ranges, measured in mbar or Torr (equivalent to millimeter of mercury or mmHg):

  • Rough/Low: 1000 - 1 mbar/760 - 0.75 Torr
  • Fine/Medium: 1 - 10-3 mbar/0.75 - 7.5-3 Torr
  • High: 10-3 - 10-7 mbar/7.5-3 - 7.5-7 Torr
  • Ultra-High Vacuum: 10-7 - 10-11 mbar/7.5-7 to 7.5-11 Torr
  • Torr Extreme High Vacuum: < 10-11 mbar /< 7.5-11 Torr

Various kinds of systems used in industry operate within these five vacuum ranges. At AERZEN, we offer custom-made vacuum equipment designed to meet the rigors of a wide range of industrial processes for customers all over the world. Our vacuum pump components are designed to produce, maintain, and measure a full or partial vacuum state to ensure optimal operational efficiency.

Some commonly used vacuum pump systems in industry include:

Success Story - Applications in the steel industry

During the production of high-quality steels AERZEN Vacuum Blowers are used for further processing of the melt, the so-called steel degassing.

Are Vacuum Pumps and Compressors the Same?

Vacuum pumps and compressors generate vacuum pressure using similar methods. The difference is in the physical results.

A compressor generates compressed air molecules from outside air inside a pressure tank, while a vacuum pump blower evacuates the gas molecules from any sealed room.

Vacuum blowers are customizable to various types of gases being handled (aggressive, neutral, or inert) and the different environmental conditions.

For instance, when handling aggressive gases, you should customize the vacuum equipment and fittings to handle the possible health hazards in industrial use during the access, measurement, separation, and disposal of evacuated gases.
