SF 1-6/SF+ 2-6: EFFICIENT, SILENT & COMPACT

The SF 1-6/SF+ 2-6 is a complete package uniting the element, drive motor, aftercooler and starter in a super silent acoustic enclosure to be installed directly into your work environment. It is also available as a Full Feature unit with integrated refrigerant air dryer. Three receiver mounting options are available: with an extended canopy that includes three integrated 10 liter galvanized air receivers or mounted on an internally coated 270 liter (72 gallon) or 500 liter (132 gallon) horizontal receiver.

ADVANCED SCROLL TECHNOLOGY

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.

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.

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.

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. TheTÜV 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.

CLASS	Concentration total oil (aerosol, liquid, vapor) mg/m3
0	As specified by the equipment user or supplier and more stringent than class 1
1	< 0.01
2	< 0.1
3	< 1
4	< 5

Current ISO 8573-1 (2010) classes (the five main classes and the associated maximum concentration in total oil content).
