The Roots vacuum pump is used whenever a vacuum needs to be created, such as in materials recovery, boosting solution flow rate, separation of liquid mixtures, speeding up the temperature drop or creating a specific pressure environment.

Built with technology learned from Hi-Bar Blowers Inc., the M series Roots vacuum pump is available in various models. Also called the booster pump, vacuum booster, or the Roots booster, the Roots vacuum pump is widely used in a variety of vacuum applications.

The BHR series vacuum booster pump combines into one unit various desirable features typically found in competitive Roots pumps available in local and international markets. These in-house developed Roots boosters run very quietly and come in various models, including BHR50, BHR65V, BHR80V, BHR100V, BHR125V, BHR150V, BHR175V, BHR200V, BHR225, BHR250V, and BHR300V.

Not only that, Baihui Roots vacuum pump also finds wide use in vacuum cleaning, dust collection, vacuum forming (for making blister packs or foams), vacuum casting, vacuum degassing, vacuum coating, vacuum distillation, and vacuum drying.

Roots Vacuum Pump Versus Roots Blower
While they are pretty much the same in construction, configuration, and operation, the Roots vacuum pump and Roots blower do have their own unique features that distinguish one from the other. The intake and exhaust of the Roots blower are wide open to the atmosphere, whereas the inlet of the Roots vacuum pump is connected to the system that needs to be emptied of air and the discharge end is open to the atmosphere.

Note
There has been a lot of mention of the term called vacuum lately. People think of it as a space of nothingness. This perfect vacuum, however, doesn't exist in the real world. When you hear of vacuum, it means the pressure is below atmospheric pressure. That being said, the vacuum does have a pressure. People even create the term negative pressure to describe it. All the surrounding pressure of the atmosphere will tend to rush to the vacuum area and equalize the pressure of the vacuum.

What is equally confusing is the difference between a blower and a booster. A Roots pump is called a booster when used in vacuum applications and a blower when used for positive pressure applications. Hence, some may call the Roots vacuum pump a vacuum booster, Roots booster, or a booster pump.
