Some production processes cannot tolerate even a trace of oil in the compressed air. Food, beverage, pharmaceutical, and electronics manufacturers need a compressor that protects the product while still delivering dependable plant air.
Panrui oil-free rotary screw air compressors deliver ISO 8573-1 Class 0 certified oil-free air for contamination-sensitive processes.
Oil-Free Screw Air Compressor Technology
Dry screw airends eliminate oil from the compression chamber. The rotors are designed to run without lubricant contact in the compression space, supported by water or air cooling and precision filtration to maintain clean air quality.
- No oil carryover from the compression chamber.
- Water or air cooling matched to the installation.
- Precision filtration for stable air quality at the point of use.
What ISO 8573-1 Class 0 Means
ISO 8573-1 defines compressed air purity classes for particles, water, and oil. Class 0 is the strictest oil classification and means the air is cleaner than Class 1, as specified by the equipment user and manufacturer. This is the standard buyers reference when the process requires oil-free air.
Always confirm the full air-quality specification, not just the compressor. Filtration, dryer selection, piping, and point-of-use treatment all affect the final air quality delivered to production.
Industries and Applications
- Food and beverage processing.
- Pharmaceutical production.
- Electronics and semiconductor manufacturing.
- Laboratory and medical air systems.
- Packaging and clean-room applications.
Selection and Support
Choose the unit by free air delivery, pressure, and the required purity class, then design the dryer and filtration to match. An oversized oil-free compressor can be just as costly to run as an undersized one, so size the system against a measured or calculated demand profile.
Compare oil-free units with the full rotary screw air compressor range, review the two-stage high-efficiency compressors, or request technical specifications.
