Leybold Vacuum TURBOVAC TW 70 H Turbomolecular Pump - REBUILT

The TURBOVAC models 50 to 1000 are turbomolecular pumps featuring grease-lubricated bearings. These units are engineered to pump vacuum chambers down to pressures in the high-vacuum range. A TURBOTRONIK frequency converter and a forevacuum pump are required for the operation of the TURBOVAC.

These units are not suitable for operation without a fore-vacuum pump.

We offer repair service and are capable of rebuilding, balancing and testing this pump. View our inventory of Leybold Vacuum turbo pumps.
