Coaxial units

The coaxial compressor units we supply are divided into two categories: lubricated and oil-free units. They are ideal for use in handicraft, industry and hobbies and can be applied both to compressors of our production and, with the appropriate changes, to compressors of other brands, as they meet the highest requirements in terms of power, precision, robustness.



Gis brand coaxial compressor units are made from the best materials and ensure the correct management and functioning in terms of air flow and pressure.


Dry coaxial

Based on oil-free technology, dry coaxial compressor units are ideal for use in industrial applications, dental practices, and the food industry.

Belt-driven units

The pumping units with belt transmission are available in single-stage and two-stage versions. Equipped with a cast iron cylinder for long duration, steel valve plates and stainless-steel blades for very high efficiency, they are always sold equipped with an aluminium flywheel. The cast iron flywheel is available on request as an optional extra. Our flywheels are multi-finned and balanced to optimize cooling and transmission.



The single-stage belt-driven pumping units we manufacture and distribute are available with different powers and capacities, depending on the customer’s needs.



Equipped with two cylinders, two-stage compressor units mean greater efficiency, lower noise levels and high performance. Visit the section and download the catalogue for more information.


4-cylinder two-stage

The higher the number of cylinders, the greater the efficiency. That is why our 4-cylinder two-stage compressor units are perfect for the optimal handling of large volumes of compressed air.
