The general-purpose vacuum pump GVS-500B is used as the roughing pump. Combining a scroll device and a mechanical booster, the unit is compact despite its large displacement. Equipped with wheels, the unit is easy to move.
Since an oil-free scroll vacuum pump is used, clean exhaust can be obtained and there is no need to worry about back-diffusion of lubricating oil.
The unit allows the roughing pump and booster pump to start simultaneously at the touch of a button.
When fast pumping speed is not necessary, the scroll vacuum pump can be operated individually as well by using the ON/OFF switch of the booster.
Switching the operation mode as necessary offers energy savings.
