The ZD (VSD) hybrid solution combines the advantages of oil-free screw technology, drum type adsorption dryer and the well-known piston booster technology. The result is in 100% oil-free dry air or nitrogen for medium- and high-pressure applications.

ZD is a combination of well-known oil-free screw, adsorption dryer and booster technology. Designed to increase system efficiency and reliability.


The Variable Speed Drive makes the ZDs on average 35 % more energy-efficient than fixed-speed compressors. MD dryer uses the heat of compression for further savings.
