Vacuum boosters increase both the pumping speed and final pressure of vacuum pumps, which can significantly improve the performance of vacuum systems, sometimes up to ten times.

They operate on the proven Roots principle: two synchronously rotating rotors inside the casing transport gas between themselves and the casing, without contact between themselves or with the casing. This means that no lubricants or operating fluids are required in the compression chamber.

The rotors are driven by gears at the ends of the gearbox, separated from the compression chamber. This ensures accurate synchronous alignment of the rotors.

Vacuum boosters can operate with or without a mechanical bypass valve. Without a bypass valve, the maximum differential pressure between inlet and outlet must be monitored during operation. Boosters with a bypass valve divert a portion of the pumped medium, automatically reducing the differential pressure and protecting the booster from overload.

Main use sectors:

Industrial Processes: Providing air for combustion in furnaces, pneumatic conveying of bulk materials, aeration in wastewater treatment plants and vacuum systems for various industrial processes.

Wastewater treatment: aeration in wastewater treatment plants to promote the growth of aerobic bacteria for the decomposition of organic matter.

Chemical processing: providing air or gas for various chemical processes, such as oxidation, fermentation and pneumatic transport.

Vehicles: Roots blowers are often used in automobile and marine engines to increase engine power by forcing more air into the combustion chamber, a process known as boosting.
