Atlas Copco oil-free Scroll compressor SF8+ SF11+ SF15+ SF22+ FF TM
Air compression is achieved by the interaction of a fixed and orbiting scroll. Air at inlet pressure enters the compression chamber at the exterior side of the scroll element. Once air is drawn in, the orbiting scroll seals off the inlet port.As the scroll continues to orbit, the air is progressively compressed into an increasingly smaller ' pocket'. A continuous flow of compressed air leaves the scroll element through a discharge port in the center of the fixed scroll. This process is continuously repeated, resulting in the delivery of pulse-free compressed air.
The SF and SF+ ranges of oil-free scroll air compressors unite Atlas Copco's vast experience and knowledge in a class-leading package. Whereas the SF range includes a standard pneumatic controller, the SF+ range boasts the high-end Elektronikon® controller. Reliable and compact, they both answer your demands through innovative technologies and supreme energy efficiency without compromising on quality.

Variable flow technology (VFT)
All SF+ 8-22 multi-scroll compressors are equipped with the unique VFT control system The VFT system, included in the Elektronikon® controller, automatically starts and stops the scroll elements to exactly match the demands of your compressed air system The Elektronikon control algorithm ensures that the system pressure is kept within a very narrow pressure band.
WorkPlace Air System™ compressors: the sound of silence
A low noise level enables the compressor to be installed close to the compressed air application, minimizing the size of the air distribution system and reducing pressure loss and the potential for leakage. As the air treatment is completely integrated, the installation costs are substantially reduced, making multiple compressor installations practical and financially viable. To ensure maximum energy efficiency, Atlas Copco offers both traditional on/off regulating systems where the air demand is constant.
Class Zero: Theindustry StandardCLASS ZERO: THEINDUSTRY STANDARD
Oil-free air is used in all kinds of industries where air quality is paramount. These applications include food and beverage processing, pharmaceutical manufacturing, petrochemical processing, wastewater treatment, and many more. In these critical environments, contamination by even the smallest quantities of oil can result in costly production downtime and product spoilage.
