manufacturing, chemical and petrochemical processing, fermentation, wastewater treatment,

pneumatic conveying, non-woven textile manufacturing and many more. In these critical

environments, contamination by even the smallest quantities of oil can result in costly production

downtime and product spoilage, resulting in product recalls and loss of reputation.

Class 0: the industry standard

CLASS 0 MEANS:Zero risk of contamination.Zero risk of damaged or unsafe products.Zero risk of losses from operational downtime.Zero risk of damaging your company’s hard-won professional reputation.

FIRST IN OIL-FREE AIR TECHNOLOGyOver the past sixty years Atlas Copco has pioneered the development of oil-free air technology, resulting in a range of air compressors and blowers that provide 100% pure, oil-free air. Through continuous research and development, Atlas Copco achieved a new milestone, setting the standard for air purity as the first manufacturer to be awarded ISO 8573-1 Class 0 certification.

ELIMINATING ANy RISk As the industry leader committed to meeting the needs of the most demanding customers, Atlas Copco requested the renowned TÜV institute to type-test its range of oil-free compressors and blowers. Using the most rigorous testing methodologies available, all possible oil forms were measured across a range of temperatures and pressures. The TÜV found no traces of oil at all in the output air stream. Thus Atlas Copco is the first compressor and blower manufacturer to receive Class 0 certification, according to ISO 8573-1 Class 0 ed 3 2010 specifications.

kEEPING yOUR PRODUCTION UP AND RUNNINGZH+ & ZH 355-900 compressors are built using strict codes of Quality Control, and are designed, manufactured and tested in ISO 9001 accredited production facilities. They use Atlas Copco’s proven, superior turbo technology and over-sized cooling for the highest efficiency and reliability, AGMA class A4/ISO 1328 class 4 gears for low noise and vibrations, high-grade stainless steel coolers for very long lifetime, and an integrated lubrication system. The result is the highest reliability you need.

ASSURING yOUR PEACE OF MINDFrom the factory to the field, Atlas Copco has the expertise and products, service and support to meet customer demands. Through interaction and dedicated service during all stages of the process, Atlas Copco has accomplished a broad customer base around the world. Hundreds of thousands of unfailing running hours give proof of our long-term local and global service and support commitment to engineering companies and contractors as well as end customers.

DRIVING DOwN ENERGy COSTSSuperior oil-free turbo air ends provide the optimum combination of a high flow with low energy consumption. Ample sized cooling, low pressure drops and an efficient drive train result in high compressor package efficiency. Further energy savings are possible with Atlas Copco’s heat-of-compression MD, ND and XD dryers.

ZH+ & ZH range: The highest efficiency & reliability

SMARTLink*: DATA MONITORING PROGRAMA remote monitoring system that helps you optimize your compressed air system

and save you energy and cost.
