In activities such as fly ash or cement production, dense phase pneumatic conveying is used to transport goods. A reliable stream of low pressure 100% certified oil-free compressed air is essential to keep the production running smoothly. To maximize productivity in these often harsh and dusty environments, Atlas Copco’s reliable ZE/ZA compressors incorporate the latest technologies in the most solid design.

Mold cooling is one of the steps in the glass blowing process which requires high-quality low pressure oil-free air at the lowest operating cost. Atlas Copco ZE/ZA compressors provide a constant air flow with pressure ratings of up to 4 bar(e). With the promise of low energy consumption and continuous operation, these compressors create opportunities to obtain a competitive advantage.

Compressed air supplies oxygen to bacteria during fermentation to produce chemicals such as citric acid. The presence of even small oil traces will kill the bacteria and contaminate the end product. As the compressed air comes into direct contact with the process, air purity is vital. Atlas Copco’s ZE/ZA oil-free air compressors are certified according to ISO 8573-1 CLASS 0 (2001), which stands for zero risk of contamination, zero risk of damaged or unsafe products and zero risk of losses from operational downtime.

In coal-fired power plants, a continuous flow of low pressure air is used to remove sulphur dioxide from the exhaust flue gases. To guarantee uninterrupted pollution control and make sure these plants are up and running 24/7, the used compressed air solution needs to be highly reliable and energy-efficient. Atlas Copco’s low pressure ZE/ZA compressors fulfill this demand by offering a constant air flow at minimal energy costs.

Oil-free air is selected by industries where air quality is paramount for the end product and production process. These applications include food and beverage processing, pharmaceutical manufacturing and packaging, chemical and petrochemical processing, semiconductor and electronics manufacturing, the medical sector, automotive paint spraying, 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.

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 that provide 100% pure, clean 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 riskAs 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. 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 not only the first compressor manufacturer to receive CLASS 0 certification, but also exceeds ISO 8573-1 CLASS 0 specifications.

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.

Varying air demand in 92% of all installationsIn almost every production environment, air demand fluctuates depending on different factors (time of the day, week or even month). Extensive measurements and studies of compressed air demand profiles show that 92% of all compressor installations have substantial variations in air demand. Only 8% of all installations have a more stable air demand. Tests prove that even in this case, VSD compressors save energy.
