Integrating the proven benefits of screw technology, the ZS & ZS+ VSD reduces energy costs by an average of 30% when compared to lobe technology. But that’s not all. The ZS & ZS+ VSD offers 100% oil-free air – TÜV-certified according to ISO 8573-1 CLASS 0 (2010) – which is absolutely essential to avoid contamination and keep your production running smoothly. The ZS+ VSD is supplied as a state-of-the-art, ready-to-run package with completely integrated VSD convertor and proven Elektronikon® controller.

Customer benefits


  • High reliability – Incorporating our proven screw technology and long-standing internal engineering practices, and designed, manufactured and tested in accordance with ISO 9001, the ZS+ VSD gives you 24/7 reliability over its long lifetime. 


  • 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. VSD technology closely follows the air demand by automatically adjusting the motor speed and lowering system pressure, giving you even greater energy savings.

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


  • Easy installation – Delivered ready for use, ZS+ VSD blowers come as all-in-one packages including the state-of-the art Elektronikon® controller, integrated converter, forklift slots, check valve, air filter and silencers.
