Atlas Copco SF+2-6 Oil Free Mono Scroll Compressor

Atlas Copco SF+2-6 Oil-Free Mono Scroll Compressor (SF 2+, SF 4+, SF 6+)

When your operation can’t tolerate oil carryover—whether you’re powering instruments, packaging, controls, clean workcells, or sensitive production steps—the Atlas Copco SF+2-6 oil-free mono scroll compressor series delivers the kind of air quality you can build a process around. The SF+ platform is engineered for Class 0 oil-free compressed air, eliminating the risks and headaches that come with oil-lubricated designs (contaminated product, downstream clean-up, and oil disposal).

Built around Atlas Copco’s proven scroll technology, SF+ compressors compress air through the interaction of a fixed and orbiting scroll, producing a continuous, pulse-free flow—ideal for stable pressure to point-of-use equipment.

Why SF+2-6 stands out

The SF+2-6 isn’t just “oil-free.” It’s designed to be quiet, compact, and easy to live with in real facilities—often close to the point of use to reduce pressure loss and leaks across long pipe runs.

Key advantages you can sell (and customers will feel immediately):

• ISO Class 0 oil-free air to protect end products and equipment
• Low-noise scroll operation—the SF+ family is known for extremely quiet performance, with sound levels as low as 52 dB(A) in the series
• Elektronikon Touch controller for clear status visibility, warnings, shutdown protection, and maintenance scheduling
• SMARTLINK connectivity for real-time remote monitoring and optimization
• IE3 Premium Efficiency motor to help reduce operating cost

Engineered details that improve uptime

Atlas Copco didn’t stop at the compression element. SF+2-6 units are built as a refined “system” with features that protect performance over time:

• High-efficiency inlet filtration: paper cartridge filter removes dust/particles down to 1 μm before they ever reach the air end
• High-efficiency, air-cooled scroll element designed for durability and reliable operation
• Smart, service-friendly vertical layout: compact footprint, improved cooling for lower working temperatures, and vibration damping
• Optimized cooler & piping: oversized cooling and stainless-steel piping/check-valve design to boost reliability and preserve air quality

Full-Feature option: built-in refrigerated dryer (cleaner air, simpler install)

Need dry air without building a separate treatment package? The Full-Feature SF+2-6 integrates a refrigerated dryer to help prevent corrosion and moisture-related issues in your air network.

Refrigerated dryer highlights (as integrated in Full-Feature configurations):

• Targets ISO 8573-1 Class 4 air quality for moisture-sensitive applications
• Typical pressure dew point around 3°C / 38°F (based on 100% RH at 20°C / 68°F)
• No-loss condensate drain (no wasted compressed air)
• Uses R513a refrigerant in Full-Feature models

SF+2-6 performance snapshot (SF 2+, SF 4+, SF 6+)

This series is offered in 8 bar (116 psi) and 10 bar (145 psi) variants.

SF 2+ (3 HP / 2.2 kW)

• 8 bar: 8.9 cfm | 10 bar: 7.2 cfm
• Noise level: 56 dB(A)

SF 4+ (5 HP / 3.7 kW)

• 8 bar: 14.2 cfm | 10 bar: 12.5 cfm
• Noise level: 58 dB(A)

SF 6+ (7.5 HP / 5.5 kW)

• 8 bar: 20.8 cfm | 10 bar: 16.1 cfm
• Noise level: 59 dB(A)

Notes on testing: Performance is measured per ISO 1217 Annex C, and noise per ISO 2151 (tolerance 3 dB(A)).

What you’re really buying: cleaner air, less hassle, better control

If you’re done gambling with oil aerosols, messy downstream filtration stacks, or “mystery contamination” problems, the SF+2-6 series is the straightforward upgrade: oil-free air by design, quiet enough for sensitive environments, and modern control/monitoring that helps you stay ahead of downtime.

Common fits for SF+2-6

1. Laboratories and testing environments
2. Food & beverage and packaging (where oil carryover is unacceptable)
3. Electronics, CNC/controls air, and clean workcells
4. Any point-of-use air need where quiet operation matters

Included value customers care about

• Fewer air-quality surprises
• Cleaner downstream components
• Compact install near the work area
• Simple service planning via controller + remote monitoring

Atlas Copco SF+2-6 Oil-Free Mono Scroll Compressors are a strong match when you need reliable, quiet, high-quality air in a compact package—without the compromises of oil-lubricated technology.
