The Mattei Absolute Zero (MAZ) Oil-Free Air System utilizes highly advanced filtration equipment, in conjunction with a Mattei oil-lubricated compressor, to generate oil-free air that meets ISO 8573-1:2010 Class 0 or ISO 8573-1:2010 Class 1 standards.

The MAZ System packages a Mattei oil-lubricated compressor with high-efficiency coalescing filters and an advanced adsorption filter. The coalescing filters reduce oil aerosols while the adsorption filter decreases oil vapors, thereby allowing the Absolute Zero System to provide oil-free air that meets ISO 8573-1:2010 Class 0 standards for oil content.


This recent development means consumers can now achieve the highest quality of compressed air through the use of oil-lubricated compressors, which offer a number of significant advantages over traditional oil-free systems.  

Lubricated, rotary vane compressors, for which Mattei is renowned, are exceptionally durable, as much as 15 percent more energy efficient, and up to 50 percent less expensive than traditional oil-free compressors.

The MAZ System will allow industries requiring oil-free systems—such as food and beverage, pharmaceutical and semiconductor manufacturing—to save costs, energy and other resources by employing oil-lubricated systems that are now authoritatively oil-free.

With Mattei's Absolute Zero Oil-Free Air System, users can now provide the highest quality of oil-free air through the use of oil-lubricated compressors, which offer significant advantages over oil-free systems.

  • Air Quality Guarantee: The MAZ System delivers air quality to ISO 8573-1 Class 0 or ISO 8573-1 Class 1 standards. It was tested in accordance with ISO 8573-5, and was third-party performance validated by Lloyd’s Register.
  • Low Operating Costs: Simple design and long-life components couple with the slow operating speeds only Mattei rotary vane technology can deliver to produce lots of air, while consuming up to 20% less energy than rotary screw type compressors.
  • Inherently Quiet: Mattei's rotary vane compressors deliver sound levels as low as 61 dB(A).
  • Low Maintenance: In a Mattei compressor, all components are easily accessible for fast easy maintenance. Annual maintenance operations only include changing the filters and oil at predetermined intervals. Inexpensive parts and oil combine with long operating intervals to deliver significant savings over the life of the machine. Servicing of the MAZ filter is easy as piping can remain in-situ, whilst use of active carbon cartridges offers quick, clean, simple maintenance.
