The oil-free scroll air compressor is a type of positive-displacement rotary air compressor, consisting of two identical involute spiral scrolls positioned with a 180° offset. One is designated as the fixed scroll, while the other is a moving scroll driven by an eccentric shaft. As the moving scroll rotates clockwise, gas enters the compressor unit's crescent-shaped chamber through the intake port. As the moving scroll continues to rotate, the gas is continuously compressed and is ultimately discharged through the outlet port located at the center of the fixed scroll.
Advantages of Oil-Free Scroll Air Compressors:
1. Absolutely Oil-Free
The compression chamber of an oil-free scroll air compressor requires no lubricating oil and involves no metal-to-metal contact, thereby fundamentally guaranteeing the quality of the oil-free compressed air. It fully complies with the ISO 8573-1:2010 purity class standards; furthermore, having successfully passed rigorous testing by TÜV Rheinland (Germany), it has obtained the ISO Class 0 oil-free certification.
2. Exceptional Energy Efficiency
Oil-free scroll air compressors utilize imported motors and high-efficiency intake filters to enhance the overall energy efficiency of the unit. Additionally, since the compressor unit itself contains no intake or exhaust valves, pressure loss is virtually zero.
3. Low Noise Levels
Oil-free scroll air compressors employ ultra-high-precision scroll machining technology to ensure the continuity and stability of the intake and exhaust processes, thereby minimizing noise generation. Furthermore, the balanced design of the moving and fixed scrolls—combined with special anti-vibration rubber mounts located at the base—eliminates excess noise. Finally, the sound-dampening enclosure effectively isolates internal operational noise from the surrounding environment.
4. High Reliability and Low Maintenance Costs
During operation, the oil-free scroll compressor system intelligently controls the rotation of the compressor units based on actual air demand. If a single compressor module fails or requires servicing, it does not disrupt the normal operation of the remaining modules, thereby significantly enhancing the overall reliability and operational utility of the system. Moreover, the unit contains very few components, resulting in an extremely low failure rate. Additionally, there is no need to install consumable parts such as oil separators, nor is it necessary to replenish compressor cooling oil.
