SL-I series

The RENNER air-cooled SCROLLline compressors are the economical choice for applications where oil-free compressed air quality is required.

The SL-I series are high efficient compressor units due to a rigid and a contactless rotating spiral compression element, combined with the use of high-quality materials, this guarantees safe and long-lasting operation and ensures a low-pulsation compressed air flow.

The belt driven compressors are ideally suited for both short-term and continuous operation. They impress with their compact design, smooth running and high reliability. The standard futures of the SL-I series are: pressure switch, motor circuit breaker and sound insulation. From a rated output of 5.5 kW, a star-delta circuit is integrated as standard. Optional futures for all single units compressors: air receiver and/or refrigeration dryer, RENNERtronic or RENNERtronic Plus electronic controls.
