Variable Speed Air Compressors operate from 100-20% capacity,.

Press Release Summary:

Configured as air- or water-cooled, VS 135 and 170 rotary screw compressors combine Enduro + airend and AirSmart control system. Smart Mixing Valve Technology keeps air/oil mixture above pressure dew point and prevent water from condensing in compressor. While VS 135 provides 125-862 acfm, VS 170 provides 139-1,056 acfm. Both operate from 70-175 psig, exhibit respective noise levels of 76 and 77 dBA, and provides unlimited start and stop capability.

Original Press Release:

Gardner Denver VS 135 - 170 with AirSmart Control

Variable Speed Air Compressor

Quincy, IL (July 13, 2007) - Gardner Denver, Inc. (NYSE: GDI) VS 135 - 170 with AirSmart Control

Gardner Denver has expanded it line of Variable Speed, VS series compressors. The new VS 135 and VS 170 rotary screw compressors combine the ultra efficient Enduro + airend and our revolutionary AirSmart control system. Each compressor can be configured as air-cooled or water-cooled.

The design of VS 135 and VS 170 centered on a matched motor, drive and airend to guarantee efficiency results before the package was designed. The result is an extremely flat efficiency curve which is 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). Ask your local Gardner Denver distributor to show it to you, you will be very impressed.

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. The efficient design allows for operation from 100% capacity down to 20% capacity, and maintains target pressure to ± 1 psig with less storage than competition. Gardner Denver recommends 0.5 gallons per cfm while competitors typically recommend 2 to 4 gallons per cfm.

The VS 135 and VS 170 utilize Smart Mixing Valve Technology that adjusts lubricant injection temperature based on the ambient temperature so that the air/oil mixture is kept above the pressure dew point, and water does not condense in the compressor. Longer bearing life and greater reliability are the result.

The VS 135 and VS 170 design allows for ease of service and provides an extremely low noise level (76 and 77 dBA) for compressors of this size.
