Atlas Copco Sf 11 Service Manual
. Certified 100% oil-free air – SF(+) compressors provide 100% pure, clean air, complying with ISO 8573-1 CLASS 0 (2010) certification. CLASS 0 means zero risk of contamination; zero risk of damaged or unsafe products; zero risk of losses from operational downtime; and zero risk of damaging your company’s hard-won professional reputation. Extremely quiet operation – The slow speed of the scroll compression elements ensures that the SF scroll compressors are exceptionally quiet. With sound levels as low as 53 B(a), the SF is the perfect choice for your sensitive working environment. Energy efficiency – The SF scroll compressors, standard equipped with IE3 Premium efficiency motors, are suited for sensitive applications which require flexibility and energy efficiency. Unloaded power consumption is eliminated thanks to the simple start/stop control.
Advanced scroll technology guarantees an optimal free air delivery and low duty cycle applications. Low maintenance – SF scroll compressors stand for simplicity and reliability. The scroll design has a minimal number of moving parts, ensuring a long operating life with a minimum number of service interventions. Advanced control and monitoring – Whereas the SF range includes a standard pneumatic controller, the SF+ range boasts the high-end Elektronikon® controller. To maximize efficiency and reliability on the SF+ compressors, the Elektronikon® controls the main drive motor and regulates system pressure within a predefined and narrow pressure band. The Elektronikon® controller can be adapted to your specific needs with extra sensors, digital contacts, fieldbus, Internet and SMS communication functions. In combination with the ES multiple compressor controller, the operation of your complete compressor room is optimized.
The Atlas Copco SFR oil-free scroll compressor is a low maintenance compressed air solution validated for railway applications. The SFR helps railway operators to achieve punctuality and reliability, while reducing operational costs. With an absolute minimum of moving parts, the SFR package features a sturdy design suitable for applications requiring low noise levels and moderate flow rates. An SFR is rated for a 100% duty cycle and suited to the harshest environmental conditions. Next to typical installations on EMUs, DMUs, metros, LRVs and trams, the SFR has a positive track record for bus applications.
Reliability – The SFR2-11 range is a simple, highly reliable compressor package design. It incorporates a minimum of moving parts, a shaft-driven cooling fan, corrosion-resistant materials such as stainless steel and aluminum and a sturdy construction to withstand external vibrations, shock loads and projectiles.

Atlas Copco Maintenance Manual
These compressors perform in temperatures from -40°C/-40°F to +50°C/+122°F and are designed to withstand the most extreme weather conditions. Maximum uptime – The SFR2-11 range is characterized by long service intervals requiring an absolute minimum of maintenance. This guarantees an availability of more than 99,9%. Low lifecycle cost – SFR2-11 compressors are characterized by an extremely low lifecycle cost; a result of the high reliability and the long service intervals. Compact and low weight – The SFR2-11 design is extremely compact as a result of the integrated fan concept. The fan is mounted on the drive motor shaft, eliminating separate cooling systems etc.
A SFR compressor therefore needs little space for installation. The use of aluminum reduces the weight as much as possible. The Full Feature concept with integrated filters, unique SDR membrane dryers and aluminum air receivers will give you one single source to supply your system with clean dry air, without lost of energy due to high pressure drops and high purge air flows, compared to separate installations.
