Vacuum Boosters or Vacuum Enhancers for Increased Flow and Deeper Vacuum. Vacuum boosters, when combined with a primary vacuum pump, are used in high-vacuum applications to enhance airflow and process neutral gases. AxFlow offers specialized versions of vacuum boosters with bypass systems, ATEX certification, or designs tailored for the automotive industry.

Vacuum Boosters
How Do Vacuum Boosters Work?
Vacuum (or Roots) boosters significantly enhance the flow rate and vacuum level of a primary pump. Inside the housing, two rotors rotate synchronously with tight tolerances, avoiding contact with each other and the housing. They operate completely dry, without lubricants or working media in the compression chamber. The rotation draws in the medium, compresses it, and moves it through the chamber toward the outlet. Many vacuum boosters feature an integrated bypass, improving efficiency and providing overload protection.
Benefits of Vacuum Boosters
Vacuum boosters offer numerous advantages, making them a popular choice for reliable flow and vacuum enhancement:
- High Efficiency: Boosters significantly improve the performance of a primary vacuum pump or multiple pumps by increasing flow rate and vacuum level.
- Flexibility: Can operate with multiple vacuum pumps simultaneously and connect to various pump types, achieving optimal efficiency when paired with screw pumps.
- Energy Savings: Achieve the desired vacuum and flow with lower energy consumption, reducing operating costs.
- Versatile Applications: Suitable for a wide range of industrial and hygienic applications, including ATEX-certified boosters for explosion-risk areas.
- Robust Design and Easy Maintenance: Durable construction ensures reliable operation and long service life, with simple designs for straightforward maintenance.
