Atlas Copco is an undisputed powerhouse in compressed air technology, boasting over a century of unrivalled expertise that has solidified its dominant position on the global quality-air stage. This vast knowledge, coupled with ever-advancing technologies, is exemplified in the organisation’s Class Zero range of oil-free air compressors and blowers. Representing the pinnacle of Atlas Copco’s relentless commitment to quality and innovation, these machines deliver 100% oil-free compressed air that is pivotal for critical process applications that require the highest air purity.
It therefore comes as no surprise that Atlas Copco holds two highly acclaimed certifications: It is the world’s first compressor manufacturer to receive certification according to the latest edition of the industry standard of air purity: ISO 8573-1 CLASS 0 (2010), and Atlas Copco also holds an ISO 22000 certification for its oil-free production facility in Antwerp, Belgium, which applies to all Atlas Copco Z type Class Zero oil-free air compressors and matching dryers and filters.
Manufacturing sectors such as food & beverage, medical and health care, automotive (paint spray), chemical and petrochemical, electronics, textile and wastewater treatment operate in critical and sensitive environments. Here the smallest amount of oil contamination can lead to significant downtime, product contamination and spoilage, resulting not only in exorbitant costs but also posing serious health and safety risks with potential legal implications. These sectors subsequently demand stringent contamination controls in their operations and therefore rely on 100% oil-free compressed air to ensure that product purity is never compromised.
Atlas Copco has incorporated its Class Zero oil-free air technology into an expansive compressor line-up that includes Rotary Screw (ZR/ZT series), Screw, Piston, Scroll, Reciprocating and Centrifugal machines.
Before exploring the features and benefits of these compressors, JC Lombard, Business Line Manager for Compressor Technique’s Oil-free Air division suggests that it’s prudent to first clarify the meaning of Class Zero. “Class Zero signifies the highest level of compressed air quality, in other words, compressed air used in industrial manufacturing processes and operations remains free from oil contamination. To ensure this, Atlas Copco has engineered its oil-free compressors to generate compressed air without any contact with oil throughout the compression process. So, the term Zero signifies Zero contamination and Zero compromise, guaranteeing the purity of the final product.”
Oil-free technology revolutionises efficiency, offering a host of benefits. This innovation eliminates the need for filter replacements, minimises energy consumption and decreases maintenance requirements and condensate treatment, thus streamlining processes and lowering overall operational costs.
In addition to optimising production, the adoption of Atlas Copco’s Class Zero oil-free solutions aligns with environmental compliance. By eliminating oil use and minimising the risk of leaks, this green technology reduces the potential for soil and water contamination. Furthermore, oil-free systems are designed to operate with higher energy efficiency, leading to less energy waste and lower carbon emissions. This dual benefit of enhancing operational efficiency while safeguarding the environment positions oil-free technology as a responsible choice for companies that demand uncompromising oil-free air and are committed to sustainability and regulatory adherence.
