The Welch 1374B-01 achieves \u0026lt; 0.001 Torr with a pumping speed of 650 liters\/min (23 CFM).\u003cbr\u003e\u003cbr\u003eTwo stage, oil sealed vacuum pumps should not be operated continuously at pressures above 1 Torr. Operating this DuoSeal vacuum pump at higher pressure will induce excessive oil spraying from the exhaust of the vacuum pump causing premature failure and void warranty.
