Kaeser has redesigned its SK rotary screw compressor series. Now SK models are more efficient, easy to maintain, offer a smaller footprint, and provide greater flow at 46-89 cfm with pressures from 80-217 psig. Triple vibration isolation and heavy sound proofing result in smooth and quiet operation. A single removable panel offers easy access to all preventive maintenance components, and a four-zone air cooling design promotes longer lubricant and motor life. Available as stand-alone compressor units, with integrated dryers or as AirCenter packages, and with variable speed drive. For more information visit www.kaeser.com/sigma.
