  • Oil-free rotary screw air compressor

    In industries where air purity isn't optional—it's mission-critical—you need a compressor that guarantees zero oil contamination. Our oil-free screw compressors are engineered to deliver ISO Class 0 certified air, making them the gold standard for clean, efficient, and reliable performance.

Oil free operation

No risk of oil entering your compressed air system.

Pure air

Meet the highest standard in air purity for sensitive industries. ISO 8573-1, Class 0 air.

Eco-Friendly

No oil disposal, no oil filters to replace, and reduced environmental impact.

Quiet operation

These compressors operate at around 70 dB of noise which is actually quieter than reciprocating compressor.

Low maintenance

Fewer moving parts, no oil changes, and longer service intervals.

Protects your products

Avoid contamination, minimize downtime, and maintain consistent quality.

Oil-free screw compressor

Oil-free air compressor is a type of air compressor that operates without the use of lubricating oil in the compression chamber. Instead of relying on oil to lubricate moving parts, it uses alternative materials or designs—such as Teflon-coated screw, water-based lubricants, or pre-lubricated bearings—to reduce friction and wear.

Oil-free screw compressors are used in a variety of industries

Frequently Asked Questions

What does "Class 0 oil-free" mean?

It means the air coming out of the compressor contains no detectable oil—perfect for industries with strict air quality standards.

Is an oil-free compressor more expensive?

While the initial investment is higher, oil-free compressors save money long-term through reduced maintenance, lower environmental costs, and fewer product defects. Contact us to discuss.
