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 less noise/vibration emitting than other dry vacuum pumps. They are highly valued by customers who need clean, high quality vacuum, especially in analytical and semiconductor related fields.
ISP series of vacuum pumps offer a clean vacuum environment and eliminate the nuisance of cumbersome lubricant maintenance or sealing water administration. ISP is free from installation restrictions because of its air-cooled system. ISP maintains low power consumption from atmosphere to maximum pressure. Maximum pressure is 1[Pa] High reliability
