Air Compressor Oil Free rotary scroll oil free air compressor made in China Product Description
1.Simple structure, small size, light weight; high volumetric efficiency; small vibration, low noise; low power consumption, long life; simple operation, high degree of automation; reliable operation.
2. High reliability: The scroll machine host parts numbers are only 1/8 of ordinary piston machine ; small turning radius, the line speed is only 2m / s, thus wearing is small, high mechanical efficiency.
3. Low energy consumption: Adopt intake supercharging effect and there is no clearance volume, volumetric efficiency is more than 98% or more; no suction, exhaust valve, intake, so exhaust pressure loss is almost zero.
4. Low noise: no suction, exhaust valve and complex motion mechanism, eliminating valve tapping sound ,and airflow blasting sound , suction and discharge is continuous and stable,the air pulsation is small .
5. Low maintenance costs:Few spare parts and less wearing parts, greatly reducing the possibility of replacement parts, and replacement parts have long lifespan, easy to use, low maintenance, low maintenance costs.
6. Unique three-wire meshing technology, enhancing the compressor volumetric efficiency to 98%, the energy-saving is in worldwide leading level.
7. Technological priorities, have owned the United States, Japan, Britain, France and other countries patents for inventions, unique in the compressor industry.   
8. Pneumatic power is even, the main moving parts endure a very small force, little wearing,after 30,000 hours the star wheel volumetric efficiency remained above 95%.
9. Cooperated with SKF, PEEK technology,which makes the system run smoother, longer component life and the world's leading indicator of longevity.
