Atlas Copco Air Compressors SF8+ SF11+ SF15+ SF17+ SF22+

The SF and SF+ ranges (SF8+ SF11+ SF15+ SF17+ SF22+) 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.

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.

COST-EFFICIENT,HIGH-QUALITY AIR

With a comprehensive suite of state-of-the-art oil-free compressor technologies like screw, tooth, centrifugal, reciprocating, and scroll, Atlas Copco offers optimal solutions for your specific needs. As many manufacturing processes depend on oil-free compressed air, we ensure its constant availability by stopping oil from entering your compressed air system.

PURE OIL-FREE AIR

The absence of metal-to-metal contact between the compression scrolls eliminates the need for oil lubrication within the compression chamber. This inherent design of the scroll compression principle guarantees the delivery of high-quality, oil-free air. Consequently, the SF compressor is entirely oil-free in every aspect of its operation.

ENERGY EFFICIENCY

Equipped as standard with IE3 Premium efficiency motors, the SF scroll compressors are ideally suited for sensitive applications demanding both flexibility and energy efficiency. Unloaded power consumption is effectively eliminated through the use of a straightforward start/stop control system. The advanced scroll technology further ensures optimal free air delivery, particularly benefiting low duty cycle applications.

EXTREMELY LOW NOISE LEVEL

Thanks to the slow operating speed of the scroll compression elements, SF scroll compressors (SF8+ SF11+ SF15+ SF17+ SF22+) are remarkably quiet. Sound levels can be as low as 53 dB(a), making the SF an excellent choice for installation in noise-sensitive working environments.

SIMPLICITY AND RELIABILITY

SF scroll compressors are synonymous with simplicity and reliability. Featuring a minimal number of moving parts, the compressor design ensures a long operational lifespan and requires limited service interventions. With their integrated design, Atlas Copco’s SF scroll compressors boast a minimal footprint and facilitate easy maintenance access.

PROVEN PEACE OF MIND

Atlas Copco has been a leader in oil-free compressed air technology for over sixty years, building upon extensive experience and continuous technological advancement. You can always have confidence in the product: stringent certification and testing procedures are conducted to guarantee that the air supplied meets the highest standards of quality control.

ADVANCED SCROLL TECHNOLOGY

Air compression is accomplished through the interaction between a stationary scroll and one that orbits. Air at the incoming pressure enters the compression chamber on the outer edge of the scroll element. Once the air has been drawn in, the orbiting scroll effectively seals off the inlet opening.

As the orbiting motion persists, the volume of air is progressively reduced within a shrinking ‘pocket’, causing it to be compressed. A steady stream of compressed air then exits the scroll element via a discharge port situated in the middle of the fixed scroll. This entire cycle is repeated continuously, resulting in the delivery of compressed air that is free from pulses.

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

The compressor operates at a low noise level, so users can install it close to the point of air use. This setup minimizes the size of the air distribution system, reduces pressure loss, and lowers the risk of leakage. Since the air treatment components are fully integrated, users also benefit from significantly lower installation costs, making it practical and cost-effective to install multiple compressors. To ensure maximum energy efficiency, Atlas Copco offers both traditional on/off regulating systems where the air demand is constant.

CLASS ZERO: THE INDUSTRY 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.

First in oil-free air technology

Over the past 60 years Atlas Copco has pioneered the development of oil-free air technology, resulting in a range of air compressors 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. Click here to know what is the ISO 8573.1 – Standards for contaminants and purity levels.

Eliminating any risk

As industry leader committed to meeting the needs of the most demanding customers, Atlas Copco requested the renownedTÜV 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 the first compressor manufacturer to receive Class 0 certification, according to ISO 8573-1 Class 0 Ed. 3 2010 specifications.
