750m³ vertical oil-free oxygen compressorfor large-scale VPSA oxygen generation systems

This compressor is very popular in big VPSA oxygen generator supply system

Main function is to increase very small pressure oxygen gas to 8-10bar pipe line


Product Overview: Oil-Free High-Flow Oxygen Booster Compressor

This is a high-capacity, oil-free oxygen compressor designed as the primary booster for medium-to-large VPSA oxygen generation systems. It safely and efficiently compresses oxygen from 0.2-0.45 MPa to 14.0 MPa, featuring an intelligent control system for reliable, continuous operation in demanding industrial applications.

Key Features & Benefits

FeatureBenefit
1. 100% Oil-Free DesignUtilizes special materials and sealing technology to completely isolate the compression chamber from lubrication systems. Eliminates the risk of oil contamination, preventing combustion and explosion hazards for ultimate safety.
2. Efficient Multi-Stage CompressionEmploys a multi-stage compression cycle to manage the compression ratio effectively. This reduces exhaust temperature and cylinder load, ensuring stable, long-term operation between 2-80 bar with lower energy consumption.
3. Vertical, Space-Saving StructureThe compact vertical footprint minimizes floor space requirements, making it ideal for installation in confined equipment rooms and simplifying system integration.
4. High Flow Rate CapacityWith a standard flow rate, it is perfectly matched to the output of medium and large VPSA oxygen generators, providing ample pressurized gas for continuous production processes.
5. Advanced Intelligent Control SystemComprehensive Monitoring: Real-time tracking of outlet pressure and temperature at each stage.
Intelligent Protection: Multi-alarm functions with automatic shutdown for over-temperature or over-pressure events.
Operation Management: Built-in work timer for streamlined maintenance scheduling and operational efficiency.
