The RENNER air-cooled SCROLLline compressors are the economical choice for applications where oil-free compressed air quality is required. Highly efficient compressor units due to a rigid and contactless rotating spiral compression element, combined with the use of high-quality materials, guarantee safe and long-lasting operation and ensure a low-pulsation compressed air flow.

The compressors of the SCROLLline SuperSilent series designed for industrial use stand for 100% oil-free compressed air and extremely low-noise operation (sound level from 52 dB(A)), both for short-term and continuous operation applications.

The oil-free SCROLLline multiple systems are predestined for maximum flexibility, high free air delivery rates, quiet, and a low vibration level. When compressed air requirements fluctuate significantly or for applications requiring capacity reserves as additional safety. The units are available with two, three, or four independently operating compressor units, which are optimally matched to each other thanks to the integrated base load change circuit. Depending on requirements, only the required compressors are in operation, which reduces energy consumption to a minimum. There are no idle times.

RENNER RSW/RSWF compressors provide 100% pure, clean air that meets the ISO 8573-1 “CLASS 0” (2010) standard. This guarantees zero risk of contamination and unsafe products. The utility patent-protected, direct-driven compressors use water for sealing and lubrication. The water draws the compression heat from the compressor and permanently supplies the water-injected friction bearings. Due to the integrated water treatment, the circulation water always has a very high quality and there are no limescale deposits. The compressors are available in both air and water-cooled versions.
