On average, compressed air is responsible for 10% of industry's electricity consumption, with peaks of up to 20% of total electricity use. In addition, electricity accounts for about 80% of the total cost of a compressor's life cycle.

More efficient air compression technologies, together with the correct sizing of a system, can considerably limit energy consumption and contribute to the containment of carbon dioxide (CO2) emissions related to the use of fossil fuels. Moreover, the energy efficiency of the compressor is key to reducing its life cycle cost – a parameter that assesses the entire cost of ownership of capital goods.

Thanks to high volumetric efficiency, mechanical efficiency and low rotation speed, Mattei rotary vane compressors are designed to compress air in a more efficient and environment-friendly manner, than other air compressors.

Mattei air compressors incorporate exclusive rotary vane technology, enabling efficient production of compressed air, as well as a reduction in energy costs, CO2 emissions and machine operating costs.

Rotary vane compressors are designed to ensure a number of benefits, including:

• The process of air compression is volumetrically very efficient thanks to the elimination of air leaks during the compression phase. Unlike rotary screw compressors, where small clearances between moving mechanical parts allow for air leaks, the absence of leaks in vane compressors is due to the particular rotary vane design consisting only of a rotor, stator and vanes.
• The blades compress air without coming into direct contact with the internal surface of the stator, driven by centrifugal force during rotation, obtaining a perfect seal thanks to the presence of a film of oil.
• The structure of the machine allows minimal mechanical losses, thus achieving 90% of mechanical efficiency with much lower energy consumption.

The high volumetric efficiency, the mechanical efficiency and the low speed of rotation are said to deliver energy savings of more than 15% compared with other rotary compressors.

Rotary vane compressors are available from Rotorvane Compressor Sales, the official distributor of Mattei Compressors in South Africa.
