KUW Series Oil-Free Scroll Compressor[/caption]
A scroll air compressor is described as a scroll pump or a scroll vacuum cleaner pump.The design of rotary scroll head creates a continuous compressed air delivery during multiple stages and there is no need oil for lubrication during compression.
A scroll air compressed system runs much quieter and more efficiently than the reciprocating oil free air compressor since there are just 2 moving components in the scroll head – a fixed scroll and an orbital scroll.
Less moving components make the scroll air compressor more energy saving, more reliable running, and less mechanical failure during running. Compared to a rotary screw air compressor, a scroll air compressor is with less vibritions and much less noise.

Frequently Asked Questions
For sensitive sectors like pharmaceutical, food & beverage, and medical, even a tiny drop of oil can cause product contamination or equipment damage. Our KUW series is TÜV certified for ISO 8573-1 Class 0, ensuring 100% oil-free air for your most critical processes.
The KUW series operates at noise levels as low as 59dB—quieter than a standard office conversation. Unlike noisy piston compressors, our scroll technology allows for installation directly in laboratories or clinics without the need for a separate soundproof room.
Scroll compressors have only two moving parts—a fixed and an orbiting scroll. With fewer mechanical components, there is significantly less friction, vibration, and wear, leading to higher reliability and a much lower risk of mechanical failure.
One of the biggest advantages of the KUW series is its low maintenance requirement. The system is designed for long service intervals, with maintenance-free periods lasting up to 10,000 hours, significantly reducing your total cost of ownership (TCO).
Yes, select models include a built-in 40L stainless steel gas storage tank. We use stainless steel or aluminum alloy for pipes and joints to prevent rust, ensuring that the high-purity air remains clean from the compressor to your point of use.
Absolutely. The KUW series features a compact modular design, covering an area as small as 0.3 square meters. Its vertical, space-saving footprint makes it an ideal choice for facilities where floor space is at a premium.
Yes. We offer optional integrated post-processing equipment (dryers and filters) to ensure the air reaches medical-grade purity. We also provide different voltage options, such as 220V single-phase for smaller units, to match your facility's power supply.
