The Welch 1399B-01 Single stage vacuum pump is a rugged and robust vacuum pump for applications requiring pressures < 30 Torr. The Welch 1399B-01 achieves < 0.030 Torr with a pumping speed of 35 liters/min (1.2 CFM).

Single stage, oil sealed vacuum pumps should not be operated continuously at pressures above 30Torr. Operating this vacuum pump at higher pressure will induce excessive oil spraying from the exhaust of the vacuum pump causing premature failure and void warranty. Please consult your Chemtech Scientific Representative for consultation, should the ultimate pressure of your process run above 30 Torr.
