VTC-400 is modern high-vacuum turbomolecular Russian complex, intended to be used in industrial and laboratory vacuum installations, where it is required both to create a high vacuum (up to 10-8 mm Hg) and to ensure pumping speed of at least 400 l/s as well.

The complex includes:

  • VGTN-400 single-flow turbomolecular vacuum pump;
  • frequency converter.

The pump is equipped with ISO-KF25 exhaust flange for connection to a backing vacuum pumping system. It can be additionally equipped with ISO-KF16 flange for the pump purging with an inert gas, if required.

Combined pump cooling is provided. The current complex is able to operate with both forced-air cooling as well as water cooling.

The working orientation in space is arbitrary.

A breakthrough atmosphere is allowed which is one of the key pump’s features which became possible by the turbine manufacture from a single piece and a special, rigid bearing assembly design.

Warranty period is 18 months.

Warranty and post-warranty services are carried out by manufacturer company’s specialists, including visiting the Customer’s territory.
