Gardner Denver expands compressor line
Gardner Denver has expanded it line of Variable Speed (VS) series compressors. The new VS 135 and VS 170 rotary screw compressors combine the company's Enduro + airend and AirSmart control system. Each compressor can be configured as air-cooled or water-cooled.
The design of VS 135 and VS 170 is centered on a matched motor, drive and airend, which gives a flat efficiency curve incorporating the entire flow range of the compressor on the x axis, plotted against the power required to produce flow on the y axis (kW/100 CFM).
The VS 135 provides from 125 to 862 acfm, while the VS 170 provides from 139 to 1056 acfm. Each machine operates from 70 to 175 psig, and provides unlimited start and stop capability. Operation is possible from 100% capacity down to 20% capacity, and maintains target pressure to ± 1 psig with less storage than competition.
