Mehrer Oil-Free Gas and Air Compressors

Mehrer is one of the leading worldwide manufacturers of oil-free piston and screw gas and air compressors for sophisticated technical applications. Our production techniques meet all pertinent national and international standards and regulations.

Custom oil-free gas and air compressors

Utilisation of standardised modules and special designs has enabled us to ensure safe, reliable and flexible system operation at high temperatures and system pressures. Mehrer compressor solutions are designed and manufactured to customer specifications as a combination of compressor block with or without drive, control and monitoring modules and gas cooling, cleaning and storage elements. The selection and utilisation of special high-quality materials or surface coatings ensures that resistance to corrosion is extremely high.

The transformation from a production firm to a service company is now evident with the introduction of the new competence symbol “Powered by Mehrer” representing high-quality gas and air compression.
