Your Benefits at a Glance

  • 100% oil-free
  • High quality electric motors
  • Fully integrated silenced package
  • Single-stage, direct-driven drive maximizes efficiency and minimizes maintenance
  • High quality water injection lubricates, cools and seals the compression process, maximizing efficiency
  • Easy service arrangement

100% oil-free

Low operating temperatures and bearing loads enable maintenance free sealed bearings to be used, totally removing the need for lubricating oil in the compressor. 100% oil-free compression is therefore guaranteed and the maintenance and environmental costs associated with oil and oil filter changes are eradicated.

Steady and reliable arrangement of compression unit

  • Synchromesh gear control
  • Heavy-duty but low-loss bearings
  • The rotor and case are covered with PTFE coating resistant to super-high temperature and corrosion.

High quality electric motors

GD Compressors use the highest quality electric motors available, to ensure high quality and premium efficiency.
