CompAir Quantima™ Q-drive- delivering a major breakthrough in oil-free Air compressor technology.

Unmatched efficiency  --------- Premium reliability ----------Lowest environmental impact

No gearbox and no contact, just a single moving part spinning in a magnetic field.
Of course it’s the ultimate compressor, offering unequalled efficiencies

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 60,000 rpm.

No gearbox
No oil
No contact
No wear

Quantima™ Air Compressors deliver significant benefits over traditional technology. Energy savings of up to 25% and more are easily achievable with Quantima.

Diagram notes:

A- Magnetic Bearing
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.

B- Q-driveTM High Speed Motor
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 the costly gearbox losses and means that the compressor does not require any oil at all.



C- Inlet Filters
High efficiency inlet air filtration for effective protection of the compression assembly. The filters provide one micron, high capacity particle filtration resulting in lowest pressure drops and longest service life.

D- Stainless Steel Coolers
Packaged shell and tube intercooler and aftercooler. Comprises water in tube stainless steel straight tube design as standard for long service life and simple maintenance.

E- Q-masterTM Controller
Provides for the comprehensive control and protection of the compressor’s operation. It incorporates a touch screen panel as well as intuitive navigation and menu structure for easy-to-use operation. It also includes sophisticated control methodology and surge calibration designed to minimise energy consumption

F- Variable Speed Drive
The high frequency inverter variable speed drive acts as an electronic gearbox. Not only does it allow for the required high speeds for compression, it also provides variable speed operation to match compressor flow to plant demand and hence minimise power consumption.

G- Zero Loss Drains
The Quantima™ package is fitted with zero loss drains which automatically drain condensate from the package based on level sensors. These are fitted on both the intercooler and aftercooler and condensate strainers are also fitted on the inlet of the drains. Manual drains are also included.

H- EMC Filter and Input Choke
The Quantima™ package incorporates Input Choke on the incoming mains power to protect the compressor drive from abrupt changes to incoming power supply and also function as protection against harmonics back to the mains supply. An EMC filter is also fitted to attenuate any electro
magnetic noise at higher frequencies that may cause harm to external equipment.

I- Acoustic Canopy
The compressor is housed in a modular acoustic canopy with intelligent sound attenuation resulting in noise levels which are the lowest of any compressor in this class – just 69 dB(A).


The Quantima™ compressor is a fraction of the weight and a fraction of the size of equivalent compressors meaning it has a significantly smaller physical footprint. In addition, the compressor incorporates a soft start VSD drive to ensure there is no current peak on start up.

Quantima™ offers the lowest environmental footprint of any compressor on the market today, cutting tonnes of CO2 during manufacture, use and disposal, increasing your ‘green’ credentials and market appeal.
