Customer Benefits

Maximum Energy Savings – Integrating the proven benefits of screw technology, the ZS+ VSD range reduces energy costs by an average of 30% when compared to lobe technology.

In 2006 Atlas Copco was the first manufacturer in the world to receive such certification on an oil-free compressor.
