HELIX ATEX vacuum pumps are tri-lobe worm screw profile blowers specifically designed for vacuum plants that must convey gas free from polluting substances, oil or water: this is made possible due to the lack of sliding parts, and therefore oil lubrication within the compression chambers.

The specific and accurate lobes profiles grant high volumetric efficiency and high flow rates combined with minimized dimensions and vacuum rates that can reach 93%.
