Small type of root type vacuum pump.
In the pressure area where the pumping speed of the sub pump decreases, the pumping speed can be greatly increased.

By adopting a DC brushless motor, it can be operated at an optimum rotational speed according to the load, so vacuum exhaust from atmospheric pressure is possible.

No oil leakage to the outside of the pump due to the magnetic coupling structure.

The pump's internal seal uses a non-contact seal, which significantly reduces mechanical loss.
(Power consumption is reduced by about 60% compared to the old model).

It is possible to operate with a 100V system and a 200V system by switching the power supply inside the driver box.
