RENNER Oil Free Air Compressors produce 100% oil-free air that meets the ISO 8573-1 Class 0 standard. Thanks to Scroll and Screw oil free kompressor technology, Renner offers a wide capacity range of 1.5-120 kW. Thanks to oil-free compressors, expensive filter replacement costs are eliminated, and pressure losses caused by oil condansate are minimized. 100% oil-free air which is needed in industries such as chemistry, food, beverage, medical, electrical-electronic, petrochemical, is produced by Renner compressors with high efficiency and economically.
Oil-free Scroll Air Compressors
Renner Oil – Free Scroll Air Compressors is the most IDEAL solution for economical oil-free compressed air in the range of 1.5 kW – 30 kW! The air between two scroll elements, one fixed and the other rotating eccentrically, is compressed and pressurized. The two scroll elements get very close to each other, but thanks to precise tolerances, compressed air is produced without touching each other. This economical and innovative design guarantees quiet (58 dB) and low vibration, 10,000 hours of maintenance-free operation. The most significant advantage of Scroll compressors is that they are air cooled, they do not require any liquid refrigerant. By this means, Renner offers an unrivaled solution in its capacity range.
Oil-free Screw Air Compressors
In Renner Screw Oil Free compressors, unlike oil-injected compressors, water is injected instead of oil to cool the screw. The injected water is recovered to the system through the water separator and as a result, 100% oil-free compressed air is produced. This compressor series have models with direct drive, frequency inverter, air and water cooling between 18.5 kW – 120 kW. Cooling water features are constantly checked to prevent cooling water from losing its properties over time and damaging the screw group. It is equipped with WEG brand IE3 Energy Saving efficient motors.
