Oil lubricated single stage rotary screw technology 37-370KW (50-500HP) Patented Turn Valve™ Technology with the Electra Saver Over 40 years ago, Gardner Denver introduced the patented Turn Valve™ technology-the most efficient part load capacity control system in the industry. With infinite positions in an operating range of 40% to 100% capacity, compressor efficiency is maximized because the Turn Valve™ airend compresses only the volume of air required without affecting the built-in compression ratio at partial load conditions. This technology eliminates wide pressure fluctuations and massive storage requirements. 1800rpm 182 to 2459cfm 50 - 500hp Direct Drive Quiet Enclosed or Un-Enclosed AirSmart™ Controller
