As a leading oil free oxygen compressor manufacturer, we specialize in delivering totally oil-free compression solutions for medical facilities, industrial operations, and cylinder filling applications. Our compressors utilize stainless steel cylinders and self-lubricated piston rings to guarantee contamination-free oxygen output while maintaining exceptional safety standards for this highly reactive gas.
Product Classification by Application
Our comprehensive oxygen compressor range addresses diverse operational requirements across multiple industries. For medical oxygen applications, our low-pressure boosters (0.3-10 bar) excel in hospital pipeline pressurization and hyperbaric oxygen therapy, with models like the OW-5/4-8 providing silent operation below 75dB. High-pressure models ranging from 100 to 150 bar serve cylinder filling stations, enabling efficient oxygen storage and distribution. Our GOW-30/4-140 compressor exemplifies our four-stage compression technology, delivering 30 Nm³/h at 140 bar with air-cooling efficiency. Industrial applications benefit from our high-capacity units, including the 1100 Nm³/h VPSA booster, specifically engineered for large-scale oxygen generation systems requiring precise pressure elevation from micro-positive to 8 bar.
Core Technical Advantages
Absolute Oil-Free Design: Every component contacting oxygen undergoes rigorous degreasing protocols following international oxygen cleaning standards, eliminating combustion risks inherent in oil-lubricated systems. Our piston rings employ PTFE-based materials that self-lubricate without introducing contaminants.
24-Hour Continuous Operation: Engineered with low-speed operation (200-400 RPM), our compressors deliver extended service life while maintaining thermal stability. Interstage safety valves and temperature controllers provide real-time protection, automatically responding to pressure or thermal anomalies.
Modular Compression Stages: From single-stage boosters to five-stage high-pressure units, our configurations adapt to your inlet pressure (atmospheric to 4 bar) and discharge requirements (5 to 300 bar). This flexibility optimizes energy efficiency by matching compression ratios to your specific process parameters.
Certified Safety Compliance: All standard models carry CE marking and ISO 9001 certification, demonstrating adherence to European Union safety directives and quality management systems essential for regulated industries.
Frequently Asked Questions
What makes oil-free oxygen compressors safer than lubricated models?
Oxygen's nature as a combustion accelerant creates extreme fire and explosion risks when combined with hydrocarbon oils. Our completely oil-free design eliminates this hazard by using non-combustible materials throughout the compression path. The stainless steel cylinders and PTFE sealing components ensure zero oil contamination, maintaining oxygen purity while meeting stringent safety requirements for medical and industrial applications. Learn more about our safety features on our service page.
How do I select the appropriate compression stages for my application?
Stage selection depends on your inlet pressure and target discharge pressure. Single-stage units handle pressure ratios up to 4:1, while applications requiring 150+ bar from atmospheric pressure necessitate four or five stages to maintain safe discharge temperatures below 130°C. Our technical team analyzes your flow rate, pressure differential, and duty cycle to recommend the optimal configuration that balances efficiency with equipment longevity.
What maintenance intervals do your compressors require?
Routine maintenance focuses on piston ring and valve replacement every 4,000-6,000 operating hours, depending on duty cycle severity. Our slow-speed design significantly extends component life compared to high-RPM alternatives. We provide detailed maintenance videos and technical support to guide operators through preventive procedures, ensuring maximum uptime for critical applications.
Can your compressors integrate with VPSA/PSA oxygen generators?
Absolutely. Our low-pressure boosters are specifically designed for VPSA and PSA system integration, accepting micro-positive inlet pressures and elevating to pipeline distribution levels (6-10 bar) or cylinder filling pressures (150-200 bar). The vertical sled-mounted designs simplify installation while water-cooled or air-cooled options accommodate varying site conditions.
