ACP 120 G

Based on the multi-stage Roots technology, the ACP 120 G is the result of over 20 years of experience in manufacturing dry vacuum pumping solutions. ACP 120 G pumps provide all the benefits of clean and dry vacuum whenever particulate or oil contamination is an issue. A specific version is also available for the pump down of large chamber volumes > 1 m3.
