How our technologies give you a sustainable edge
At AF Compressors, we design our oil-free piston technologies to reduce this impact at every stage of the compressor lifecycle – from materials and components to operation, maintenance and end-of-life treatment.
This approach is aligned with European environmental regulations and with one of our core principles: energy sobriety – using only the energy that is truly needed.
About our oil free air compressed air solutions
The majority of compressors are Oil-injected or Oil-flooded Air-Compressors. During the usage, waste is produced in the form of, Oil-carry over in the air in case of Oil-flooded compressors, Oil into the filter cartridges, contaminated condensate, disposal of worn-out compressor components, disposal of the complete compressor after 10 years.
In Oil-free compressors, the three types of technologies, the Industrial Pistons, Rotaries and Centrifugal units. The waste produced by Oil-free compressors is less, as the condensate is pure water, the filters are not contaminated with Oil and there is no change of oil every 2000 hrs.
The oil-free piston air compressors are producing 100% oil-free air following to ISO 8573-1:2010. The production of air from AF compressed air systems with refrigerative air dryer is in conformity with the provisions of the directive 2003/87/CE, greenhouse gas emission allowance trading.
Heat Recovery System
At the test bench of the production site, the system equipped with a plate heat recovery for water, daily recovers the consumed power and heat dissipation of the running machines test bench into kcal/h for heating device etc.
The range of power of the compressors vary from ca. 75 up to 500 kWh, with an average value of 250 kWh. Available water temperature is ca. 90°C. This heat recovery system is used for the personnel and workers showers, as well as for the central heating.
At the test bench of the production site, a water recovery system is under development.
Long lifetime and reduced waste
Developed OPC 90-132, has very long service intervals of 8000-16000 hours, minimizing the waste from wearing components and lubrication to a minimum.
- Seals: replaced every 8,000 hours on the second stage and every 16,000 hours on the first stage.
- Valves: refurbished every 8,000 hours on the second stage and every 16,000 hours on the first stage to maintain high efficiency.
Association with the scientific associations U-Liège and UC-Louvain
AF constantly works in association with scientific associations of U-Liège namely for the analysis of the materials quality. AF Engineering permanently invests in the R&D department with partnership with UC-Louvain, Université Catholique de Louvain-la-Neuve. to develop its engineering researches to lower the carbon footprint of their equipment. Various areas for progress in energy saving and carbon footprint reduction are:
