RSW series (direct drive)

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 as both air and water cooled versions.

The low operating temperature of the water-injected air ends has an extremely positive effect on energy, maintenance and operating costs. The low speeds mean that the units are also extremely quiet.

In addition to the standard version, the RSWF series of water-injected compressors with variable speed control is available for economical operation with highly fluctuating compressed air requirements.

Both variants are equipped as standard with the RENNERtronic Plus control and the efficient IE3 energy-saving motor.
