The SF scroll series relies on a radically new technology, ensuring economy in operation, extremely quiet running, minimum servicing and space saving, thanks to its simplicity and compact design. It is equipped with a highly efficient IP55 class F electric motor.

These compressors have a minimum of maintenance requirements, 10,000 running hours practically without maintenance while intermediate routine operations remain restricted and easy to perform. Perfect for both point-of-use and regular compressor room installations, these small units deliver a high performance with minimal maintenance.

All compressors are manufactured in accordance with Atlas Copco's Quality and Environment Management System. This system complies fully with ISO 9001 and ISO 14001. All Atlas Copco dryers are tested to perform under the most demanding conditions.

• Capacity: FAD 2.1-26.4 l/s, 4.4-55 cfm nominal

• Working pressure: 7.75-10 bar(e), 116-145 psig nominal

• Motor size: 1.5-15 kW, 2-20 hp

Air compression is achieved by the interaction of a fixed and an 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 centre of the fixed scroll. This process is continuously repeated, resulting in the delivery of pulse-free compressed air.
