Atlas Copco Oil-free Air Compressors:ADVANCED SCROLL TECHNOLOGY
Air compression occurs through the interaction between a fixed scroll and an orbiting scroll. Air enters the compression chamber from the outer edge of the scroll element at inlet pressure. Once inside, the orbiting scroll closes off the inlet. As it continues its orbiting motion, the trapped air is gradually compressed into smaller and smaller pockets. The compressed air is then discharged through a central port located in the fixed scroll. This cycle repeats continuously, providing a steady, pulse-free stream of compressed air.

Oil-free air: essential for critical industries
Oil-free air is crucial in industries where air purity is vital. These industries include food and beverage production, pharmaceutical manufacturing, petrochemical processing, wastewater treatment, and many others. In such sensitive environments, even the slightest trace of oil contamination can lead to significant production losses and product spoilage.
Pioneers in oil-free air technology
Atlas Copco has led the way in oil-free air technology for over six decades, developing a broad range of air compressors that deliver 100% pure, oil-free air. Through ongoing research and innovation, the company reached a significant milestone by becoming the first manufacturer to receive ISO 8573-1 Class 0 certification—setting the benchmark for air purity.
Ensuring zero risk
With a strong commitment to satisfying the strictest customer demands, Atlas Copco partnered with the independent TÜV institute to conduct comprehensive testing of its Atlas Copco oil-free compressor range. These tests involved the most stringent methods, measuring all forms of oil under various temperatures and pressures. The results confirmed that no oil was detected in the compressed air output. As a result, Atlas Copco became the first compressor manufacturer to earn Class 0 certification in accordance with ISO 8573-1 Class 0 Edition 3 (2010), eliminating any risk of oil contamination.

Surprised me most was how quiet it operates!
After running our dental clinic for 15 years, switching to the Atlas Copco SF4+ was the best decision we’ve made. The complete absence of oil contamination gives us peace of mind for patient safety. What surprised me most was how quiet it operates – our patients no longer complain about compressor noise during procedures. Maintenance is a breeze compared to our old oil-lubricated unit – just basic filter changes every 6 months. After 18 months of heavy use (10+ hours daily), it hasn’t skipped a beat. The energy savings are noticeable on our utility bills too. While the upfront cost was higher, the reliability and zero downtime have more than paid for itself. This is professional-grade equipment that actually delivers on its promises.
