Anest Iwata

GVSU 500B

ANEST IWATA was the first in the world to develop the air-cooled, oil-free, scroll-type vacuum pumps. Our oil-free, scroll vacuum pumps are compact and emit less noise and vibration than other dry vacuum pumps. They are highly valued by customers who need clean, high quality vacuum, especially in the analytical and semiconductor related fields.

The GVSU-500B scroll pump is equipped with a dry vacuum system so there is no need for lubricating oil or sealing water. The absence of gears means that it is low-maintenance and there is no need to change gear oil and no risk of lubricating oil leaks. Generator powered vacuum keeps the installation area clean. It is equipped with a water cooling system which eliminates the need to control water cooling on site. The GVSU-500B pump is excellent in displacing water vapor. Low power variance between atmospheric pressure and maximum pressure allows repeated, continuous operation between atmospheric pressure and vacuum. This pump uses up less energy and can lead to savings in the vacuum area. 24-Hour operation secured.

Application for oil-free scroll pump
