Vacuum Duty Twin Lobe Blower
Vacuum Duty Twin Lobe Blower
A Vacuum Duty Twin Lobe Blower is a type of positive displacement blower that is designed to operate under vacuum conditions. It is also known as a vacuum pump or vacuum compressor.

The blower consists of two lobes or rotors that rotate in opposite directions within a casing. As the rotors rotate, they create a low-pressure zone that draws in air or gas through the inlet port. The air or gas is then compressed and expelled through the outlet port. The blower can create a vacuum, which is useful for applications such as vacuum drying, vacuum packaging, and vacuum conveying.
The twin lobe blower is designed for heavy-duty applications and can handle continuous operation at high vacuum levels. It is typically used in industries such as chemical processing, pharmaceuticals, food and beverage, and wastewater treatment.
The blower is available in different sizes and configurations, and can be customized to suit specific application requirements. It is important to select the right blower size and type for the application to ensure efficient operation and long service life.
What is blower function in vacuum?
In a vacuum system, the function of a blower is to create a low-pressure or vacuum environment by removing air or gas from the system. The blower is typically used to extract gases, fumes, or vapors from a process or from a specific area.
A blower works by drawing air or gas into the system through an inlet port, then compressing and expelling it through an outlet port. The blower creates a pressure difference between the inlet and outlet, which generates a flow of air or gas that carries the material being removed.
In vacuum systems, blowers can be used for a variety of purposes, including:
Vacuum conveying: to move materials from one location to another in a vacuum environment.
Vacuum packaging: to remove air from a package to extend the shelf life of food or other products.
Vacuum drying: to remove moisture from materials, such as in the production of pharmaceuticals.
Wastewater treatment: to remove fumes and gases from water treatment systems.
Blowers used in vacuum systems are designed to operate at high efficiency and maintain a stable vacuum level over an extended period of time. Proper selection and maintenance of the blower are important to ensure efficient operation and long service life of the vacuum system.
Vacuum Duty Twin Lobe Blower Application
Blowers have a wide range of applications in different industries, including:
Industrial processes: Blowers are used in various industrial processes, such as material handling, ventilation, and combustion air supply. They can provide the required air or gas flow and pressure to support the process, and can be used in industries such as cement, steel, chemical, and petrochemical.
Water and wastewater treatment: Blowers are used in water and wastewater treatment plants to provide aeration and agitation for biological treatment processes, such as activated sludge and aerobic digestion. They can also be used to supply air for oxidation and disinfection processes.
Pneumatic conveying: Blowers are used in pneumatic conveying systems to move materials, such as powders, granules, and pellets, from one location to another. They can be used in industries such as food processing, pharmaceuticals, and plastics.
HVAC systems: Blowers are used in heating, ventilation, and air conditioning (HVAC) systems to move air through ducts and distribute it to different areas of a building. They can be used in residential, commercial, and industrial buildings.
Vacuum systems: Blowers are used in vacuum systems to create low-pressure or vacuum environments for various applications, such as vacuum packaging, vacuum drying, and vacuum conveying.
The specific application and requirements of the blower will dictate the type and size of the blower needed. It is important to select the right blower for the application to ensure efficient operation and maximum performance.
Vacuum Duty Twin Lobe Blower Specifications
The specifications of a blower will vary depending on the application, but here are some common specifications to consider when selecting a blower:
Flow rate: This is the amount of air or gas that the blower can move through the system in a given period of time, usually measured in cubic feet per minute (CFM) or liters per second (L/s).
Pressure or vacuum level: This is the amount of pressure or vacuum that the blower can create, usually measured in inches of water (in. H2O) or pascals (Pa).
Power rating: This is the amount of power required to operate the blower, usually measured in horsepower (HP) or kilowatts (kW).
Speed: This is the rotational speed of the blower, usually measured in revolutions per minute (RPM).
Efficiency: This is the ratio of the amount of air or gas moved by the blower to the amount of power consumed, usually expressed as a percentage.
Construction material: The blower casing and rotors can be made of different materials depending on the application, such as cast iron, aluminum, or stainless steel.
Noise level: The noise level of the blower can be an important consideration, especially for indoor applications. The noise level is usually measured in decibels (dB).
Environmental conditions: The blower should be designed to operate under the specific environmental conditions of the application, such as temperature, humidity, and altitude.
It is important to select a blower that meets the specific requirements of the application to ensure efficient operation and maximum performance.
