Oil-free compressors are essential for clean-air applications but cost more and need different maintenance. Here is what to know before buying.
Air Quality
- Oil-free machines provide certified clean air.
- Choose the right ISO 8573 class.
- Filtration still protects against ambient contamination.
Cost
- Higher purchase price than oil-injected.
- May have different maintenance needs.
- Energy and quality benefits justify the cost where required.
Maintenance
- Oil-free air ends need specialist service.
- Intervals differ from lubricated machines.
- Use only recommended parts.
Is oil-free air really free of oil?
It means the compressor adds no oil. Ambient oil vapour is still removed by filtration.
