Oil free screw air compressors use oil-free technology to produce pollution-free compressed air, suitable for food, pharmaceutical and other industries. Its design is efficient and energy-saving, with low operating noise, low maintenance cost, long life and stable and reliable characteristics. Oil free screw air compressors can meet the needs of various industrial applications for high-quality, pure compressed air. Olymtech company offers a comprehensive range of oil free screw air compressors, featuring both fixed-speed and variable-frequency drives.

Features of Oil Free Screw Air Compressor

1. Quality Control:
Raw material inspection at the source to eliminate potential risks.
100% operator self-inspection during assembly, including quality process sampling.
100% shipment inspection before packaging, with daily spot checks by quality engineers and bi-weekly team product reviews.

2. Zero Pollution Risk:
TÜV Oil-Free Certification ensures a sealed, lubricated, and cooled air-end using pure water, eliminating lubrication pollution risks.
Compressed air-ends and air pipelines are made of stainless steel, eliminating corrosion pollution risks.

3. High Efficiency:
Low consumption design with excellent water cooling capacity, achieving an isothermal compression process.
Approximately 10% more air produced by recovering compression heat waste.
The expansion coefficient of cryogenic compressed air reduces component pressure, extending service life.

4. Low Maintenance Cost:
Water filter: 1000-hour replacement cycle.
Air filter: 2000-hour replacement cycle.
Motor grease: 2000-hour replacement cycle.
Water waste: approximately 40L every 50 hours (37kW).
Overhaul cost is approximately 10% of the whole compressor value (for star wheel and bearing replacement).

5. Low Noise:
Operates with lower noise compared to other oil-free technologies, no vibration, and no need for an installation base.
Other oil-free technologies can be noisy and have high vibration values, and some may require an installation base.

6. Stability:
Uniform air-end force extends the air-end service life.
Air-end speed does not exceed 3600 RPM/min.
Low operating temperature ≤60°C.
Easy to install, no need for exhaust ducts, and no additional oil removal equipment required.

7. High-Quality Spare Parts:
Controller & Inverter: Support remote start and stop/operation signal/fault signal/warning signal, with real-time power consumption and cumulative power consumption measurement. Timing start and stop function selection, timing pressure function selection. 2pcs RS485 communication port, can control any inverter supporting MODBUS RTU protocol, offering a more flexible choice.
Motor protection function: phase loss, overload, unbalance, overvoltage, and undervoltage. Highly integrated, highly reliable, and cost-effective.
Motor: Fixed speed motor (IE2 efficiency level, IP54 protection level) or Permanent Magnet VSD motor (IE3 efficiency level, IP55 protection level).
Electrical Components: Schneider or Siemens electrical components, standardized design, safe and reliable.
Danfoss Solenoid Valve: More sensitive, safe, and reliable.
Donaldson Filter Element: A leader in the filtration industry, with a filtration efficiency of 99.9%.
