This factor is worth considering if you have sensitive hearing or live in an apartment where noise carries. A high decibel level means a loud vacuum and one that is likely to disturb your peace. You'll want to look for vacuums with a low decibel level, around 50 dB or less.
WebUltra-high vacuum (UHV) is the vacuum regime characterised by pressures lower than about 100 nanopascals (1.0 × 10 −7 Pa; 1.0 × 10 −9 mbar; 7.5 × 10 −10 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 … WebIn most cases, the exhaust is connected to a mechanical backing pump (usually called roughing pump) that produces a pressure low enough for the turbomolecular pump to …
