Venturi vacuum generators use the flow of motive fluid such as air, steam, or liquid to evacuate air. They include one or more stages of the same technology type (mechanical or Venturi), or two or more different types of pumps packaged together. Single-stage devices move air directly from the chamber into the atmosphere. Two-stage devices evacuate air in two stages for lower absolute pressure. Venturi vacuum generators with three or four evacuation stages are also available. Benchtop models are small enough to sit atop a bench or table. Portable products include wheels, casters, or an easily movable frame for frequent relocation. Larger Venturi vacuum generators are designed to rest on the floor or on a skid. Products that are designed for permanent installation are also available.    

Ultimate operating vacuum and pumping speed are the most important specifications to consider when selecting Venturi vacuum generators. Typically, vacuum is measured in torr or millimeters of mercury (mm Hg) referenced above absolute zero pressure. Venturi vacuum generators provide three levels of ultimate operating vacuum: rough vacuum (1 torr and above), medium vacuum (0.001 to 1.0 torr), and high vacuum (below 0.001 torr). In addition, some suppliers use terms and standards such as medium vacuum and ultra-high vacuum. Pumping speed or displacement is the vacuum pump’s air volume capacity. Vacuum pumps are flow-rated according to the volume of air exhausted with no pressure differential across the pump. 


Products & Services Related to Venturi Vacuum Generators
High Vacuum Pumps
High and ultrahigh vacuum pumps operate efficiently in the high vacuum region and develop molecular flow for highly evacuated systems.
Mechanical Vacuum Pumps and Systems
Mechanical vacuum pumps and systems contain devices such as pistons, claws, scrolling spirals, and diaphragms to isolate and compress air.
Regenerative Blowers
Regenerative blowers are low pressure, high volume blowers that generate centrifugal airflow.  They are used in compression, vacuum, and industrial blower applications.
Rotary Vane Vacuum Pumps and Systems
Rotary vane vacuum pumps and systems move media through the pump using a rotating assembly in the pumping chamber. Typically, there are two or more rotating vanes that move the media from inlet to outlet. Rotary vane vacuum pumps are positive displacement pumps.
Vacuum Pumps and Vacuum Generators
Vacuum pumps and vacuum generators provide sub-atmospheric pressure for a variety of industrial and scientific applications where a vacuum is required.
