Venturi Vacuum - Instructables

But the venturi needs a very high air speed to reach low pressures, and spend a lot of air in the process. The compressor intake can work as a high volume vaccum pump, and the lowest pressure depends on the motor power and piston diameter. I build one venturi pump, and it isn't energy eficient.

Working Flow Rate: How to Compare Vacuum Pumps .

Often overlooked in selecting a vacuum pump, however, is the importance of flow rate (also called pumping speed or air displacement) in matching a vacuum pump to an application. A pump's flow rate is simply the volume of gas or vapor it can move per unit of time, with units variously reported as liters per minute (lpm), cubic feet per minute .

Ultra-high vacuum - Wikipedia

Ultra-high vacuum (UHV) is the vacuum regime characterised by pressures lower than about 100 nanopascal (10 −7 pascal, 10 −9 m bar, ~10 −9 torr).UHV conditions are created by pumping the gas out of a UHV chamber. At these low pressures the mean free path of a gas molecule is greater than approximately 40 km, so the gas is in free molecular flow, and gas molecules will collide with the .
