Design Advantages

Design Advantage

Rotors

  • Highly efficient patented KyphoTM  rotor profile.
  • Precision milled to exact tolerances.
  • Long-life cylindrical and tapered roller bearings ensure reliable, consistent operation.
  • Extended bearing life due to vibration-free performance.

Oil Separator

  • EliminatorTM  air/oil separator has two times the surface area of conventional separators for improved separation and longer life.
  • Low carry-over; less than two parts per million, measured before the aftercooler at 100 psig, full load operation.

Maintenance

  • Simplified access to air/oil separator requiring no piping removal to change separator elements. Reduces maintenance time by 90%.
  • Easy access to the full-flow, ten micron oil filter. Reduces time to complete periodic oil filter changes.
  • Simple, patented system for adjusting belt drives.

Acoustic Enclosures

  • Low overall noise level; Quiet enclosure option reduces sound to 76dBA.
  • Unrestricted access to airend and motor provided by lift-off panel.

Control Piping

  • Safe, corrosive-free compressor operation is a direct benefit from stainless steel control lines, a standard Gardner Denver feature.
  • No plastic tubing, rubber hoses or black piping.

Mounted Aftercooler

  • Factory mounted, heavy duty, air-cooled aftercooler and moisture separator with trap effectively reduces discharge air temperature to within 15°F of ambient.

Auto Sentry® RS-2000 (ES40/ES-50)

  • Complete electronic control with complete self-diagnostic, protective shutdown, service advisory and full text digital display capabilities.
  • Built-in selectable automatic re-start and sequencing (up to 8 units).
