Roots Blower Vacuum Pumps: Dry Vacuum Solutions

The best choice for processes requesting a vacuum level up to 100 mbar abs.

Advanced Technology For Vacuum Application

Hibon has over 100 years experience in providing technology leading industrial vacuum solutions. Over the years we have built up a reputation of excellence and innovation.

We strive to enhance and deliver products, services, and technical solutions that exceed our customers' expectations. 

Our rotary lobe blowers use innovative air cooled or water cooled technology to achieve high performance while staying energy efficient.

Reliable and robust, our vacuum pumps and accessories are sized to meet the needs of each plant circumstance.

They are an alternative to water-based or oil technologies such as liquid ring pumps or oil sealed vacuum pumps.

Our vacuum solutions offer many advantages:

  • energy reduction, 
  • seamlessly adaptation to varying production rates 
  • and maintaining unwavering vacuum stability.

Our vacuum pumps use reliable roots vacuum pump technology to create high-performance for many applications.

Roots blowers  move large volumes of air at relatively low pressure differentials. They are particularly effective for applications requiring rapid extraction of air.

These positive displacement vacuum pumps are particularly effective in demanding applications such as:

  • Pulp and paper drying processes 
  • Filtration
  • Precision pick and place operations in the canning industry
  • Vacuum pneumatic conveying
  • Vacuum packaging
  • Environmental cleanup

How does run a roots blower as a vacuum pump?

Using a Roots blower as a vacuum pump means using its principle to create a vacuum in a closed system, hermetically sealed for creating a closed environment.

  • Setup: Connect the inlet of the Roots blower to the system from which you want to remove air. 
  • Operation: Roots blower operates to let its rotating lobes draw air from the connected system through the inlet and outlet by creating suction. As the lobes rotate, they trap and move the incoming air or gas towards the outlet of the blower. This action creates a lower pressure inside the blower compared to the surrounding environment, resulting in a vacuum effect.
  • Discharge: The blower discharges the air or gas through the outlet, effectively extracting it from the connected system and maintaining the vacuum.
  • Monitoring: Use appropriate gauges or sensors to monitor the vacuum level within the system and ensure that you achieve and maintain the desired level of vacuum.

Key aspects regarding Roots Vacuum Pumps & Package

Ultimate pressure is an important specification for vacuum pumps and systems, as it indicates their capability to create and maintain a vacuum. 

Ultimate pressure refers to the lowest pressure that a vacuum system can achieve under ideal conditions. It represents the maximum level of vacuum that the system can attain, typically expressed in units such as Torr, millibar, or Pascal. 

For a Roots vacuum pump, atmospheric pressure also plays a crucial role. In the context of a Roots vacuum pump, atmospheric pressure refers to the pressure of the air surrounding the pump on the inlet side.

When operating as a vacuum pump, the Roots pump creates a lower pressure within the system compared to atmospheric pressure. This pressure difference allows the pump to evacuate air or gas from the system, effectively creating a vacuum.

Understanding atmospheric pressure is important for Roots vacuum pumps because it helps determine the level of vacuum that the pump can achieve. The difference between atmospheric pressure and the pressure generated by the Roots vacuum pump dictates the level of vacuum attained within the system.

 These pumps are known for their high pumping speeds, making them suitable for applications requiring rapid evacuation of air.

The pumping speed of a Roots vacuum pump refers to the volume of air that it can remove from a system per unit of time, typically expressed in cubic meters per hour (m³/h).

Although Roots blowers can effectively create a vacuum, users typically employ them for applications that require relatively low vacuum levels.

Users often combine Roots blowers with other types of vacuum pumps, such as rotary vane pumps or liquid ring pumps, to achieve the desired vacuum level for applications that require higher vacuum levels.
