What is VPSA Technology?
VPSA (Vacuum Pressure Swing Adsorption) is an advanced gas separation process that combines pressure swing adsorption with vacuum regeneration. Unlike traditional PSA systems (which rely on high-pressure compression), VPSA uses vacuum pumps to desorb adsorbed gases, significantly reducing energy consumption by 30-50%. This makes VPSA ideal for large-scale, continuous oxygen production in industries requiring stable gas supply.
Advantages of VPSA-O2 Series
- Energy Efficiency: 40% lower energy consumption vs. PSA systems, ideal for 24/7 industrial use. Vacuum pumps reduce carbon footprint and operational costs.
- Scalability: Modular design allows easy expansion from 200 Nm³/h to 10,000 Nm³/h.
- Smart Operation: Real-time monitoring of O₂ purity, flow, and pressure via IoT-enabled platforms. Automatic fault diagnosis and remote upgrades.
- Low Maintenance: Vacuum pumps have a lifespan of 10,000+ hours with minimal servicing. Built-in molecular sieve protection alarms extend component life.
- Custom Solutions: Tailored for industries like steel mills, wastewater treatment, and power plants.

FAQ
Q: How does VPSA differ from PSA?
A: VPSA uses vacuum regeneration, reducing energy use by 30-50% and enabling continuous output, while PSA relies on high-pressure cycles for smaller, intermittent applications.
Q: What air quality is required?
A: Compressed air must meet ISO 8573-1 Class 6 (dust <0.1 mg/m³, oil <0.01 mg/m³). Our systems include integrated air treatment for compliance.
Q: Can the system operate in harsh environments?
A: Yes. The VPSA-O2 Series functions in temperatures from 5°C to 45°C and altitudes up to 3,000 meters with optional cooling packages.
Q: How quickly can installation be completed?
A: Compact skid-mounted designs allow for installation within 3-5 days. Custom systems may require 2-4 weeks for setup.
Q: What is the oxygen purity guarantee?
A: Standard purity is 90-93% O₂. For higher purity (up to 99.5%), we offer optional post-purification modules.
