Pfeiffer Adixen Alcatel 2021i Instrument Pascal Rotary Vane Vacuum Pump - REBUILT

Rebuilt with one year warranty. Pfeiffer Adixen Alcatel 2021i Instrument (analytical series) Pascal rotary vane vacuum pumps. These have dual voltage: 115-230V motors and the optional internal oil pump. This pump is necessary when the ballast is used for extended periods but is not advisable for pumps running with particulate in the oil. We have added have the standard manual ballast since we received them with automatic ballasts. Fill out our request for quote form for other concerns.
