New range of non-lubricated industrial scroll compressors MSS

February 2, 2021

MAC3 is pleased to announce the introduction of the MSS industrial range, based on oil-free scroll compression technology. This new range is designed to meet a wide range of applications where oil-freecompressed air is required. Compressors that do not use oil in the compression process avoid any risk of contamination in the manufacturing process.

industrial compressors with non-lubricated spirals


Multiple applications

Many processes involve contact betweencompressed air and product. Where air purity is critical, totally oil-free air is required, such as
such as for example :

  • Pharmaceuticals;
  • Food manufacturing and transportation;
  • The manufacture of electronic components;
  • Dental laboratories;
  • High technology and R&D;
  • Water treatment;
  • Etc...


The compression block manufactured in Japan by HITACHI, is composed of 2 spirals, one fixed and one mobile. The latter, by its rotation, compresses the air that enters the compression chamber.

The compressor blocks incorporate an optimal cooling system and all models come with a high efficiency compressed air aftercooler.


The compressors have been designed to achieve very low vibration and noise levels.


As standard, each compressor is equipped with an intelligent electronic controller, allowing for preventive maintenance management and communication via MODBUS protocol.


And finally, the French touch with our LEROY SOMER IE3 motors and our SCHNEIDER ELECTRICS starters and electrical protections.

Scroll motor


From 1.5 to 30kW, the MSS range can meet a wide range of oil-free air requirements.

The MSS range offers models with up to 4 compressors in the same chassis and is divided as follows

  • S = 1 scroll compression unit
  • D = 2 spiral compression units
  • T = 3 spiral compression units
  • Q = 4 scroll compression units

The multi-compressor models D, T and Q, are driven by an advanced electronic controller, allowing to manage the start/stop, rotation and balancing of the compression units, with the main objective of a perfect match between consumption and production of compressed air.
Finally, the S models with only one compression unit can be delivered mounted on an air receiver with refrigeration dryer and filtration.
