Welsh 8917A 2 stage vacuum pump 6.1CFM, 115v

The Welch 8917A Direct Drive vacuum pump is a robust vacuum pump for applications requiring pressures < 1 Torr. The 8917A achieves < 0.001 Torr with a pumping speed of 173 liters/min (6.1CFM).                                                         

Two stage, oil sealed vacuum pumps should not be operated continuously at pressures above 1 Torr. 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.
