The Next Generation of Efficiency

Oil-Free Two-Stage Variable Speed Centrifugal Compressors

Think of it as the best compressed air insurance you can get...

quantima-in-situAir purity is critical for many applications where even the smallest drop of oil can cause product spoilage, or damage the production equipment. Quantima, a completely oil-free compressor eliminates all possible risks associated with oil and silicone contamination. It is designed and manufactured to give compressed air users complete peace of mind and provides 100% air purity, certified ISO 8573-1 (2010) Class 0 and silicone-free!


Breakthrough oil-free compressed air technology

The CompAir Quantima centrifugal air compressors deliver significant benefits over traditional technology. Offering outstanding energy efficiency, reliability and low environmental impact, Quantima also offers low noise levels at 69 db(A) and a physical footprint around 25% smaller than comparable compressors in the market.

What makes Quantima® special?

Quantima’s patented Q-drive compression and motor assembly has just one moving part and operates with the rotor spinning in a magnetic field at up to 76,000 rpm.

  • Superb efficiency due to no gearbox and no contact parts
  • Variable speed technology minimising off-load running
  • Outstanding energy savings of up to 25% are easily achievable
  • No performance degradation
  • Lowest off-load power consumption of just 2.5% of full load power, equal to 7 kW for a 300 kW compressor
  • Smallest physical footprint
  • Lowest noise levels of just 69 dB(A)


Advanced Quantima® Technology

The patented Q-drive motor incorporates an asynchronous induction design and operates at high speeds to avoid the need for a conventional gearbox. This eliminates costly losses and means that the compressor does not require any oil at all.

The motor and direct drive compression assembly incorporates magnetic bearings to provide stable control, both axially and radially of the rotor shaft. The shaft is supported in a magnetic field which means that there is no contact and no wear, ensuring reliable operation and long life without performance degradation.

In addition to Quantima's patented Q-drive technology which ensures reliable operation and longer life without performance degradation, these compressors incorporate a variety of innovative design features, delivering the ultimate efficiencies.

Simplicity. The ultimate in 'peace of mind'.

Less is more... Quantima is special for what it doesn’t have:

  • No gearbox
  • No oil
  • No oil-laden parts
  • No contact
  • No wear
