Advanced Engineering Highlights
Zeolite Sieve Dynamics
The core of our VPSA system uses specialized synthetic zeolite. Unlike standard sieves, our proprietary molecular sieve material is optimized for vacuum-assisted regeneration, preventing premature degradation.
Flow Control Logic
The VH5 series utilizes a digital flow-control valve that ensures oxygen output remains stable, even if the patient's breathing pattern fluctuates, preventing "concentration dips."
The VPSA Thermodynamic Cycle
- Stage 1: Ambient Intake: Multi-stage intake filtering removes particles down to 0.3 microns.
- Stage 2: Compression & Cooling: Atmospheric air is compressed at a lower, more efficient ratio than traditional PSA.
- Stage 3: Adsorption Phase: Nitrogen is selectively adsorbed by the zeolite bed while oxygen passes through into the product tank.
- Stage 4: Vacuum Desorption: The system reverses pressure using a high-efficiency vacuum pump, purging nitrogen from the sieve bed and resetting it for the next cycle.
Technical FAQ
Why does the lower operating pressure matter?
Traditional PSA systems use high pressure, which causes mechanical stress and heat. VPSA's lower pressure reduces internal wear, lowers energy consumption by 30%, and drastically reduces operating noise (33dB).
How does it maintain purity at high altitudes?
The VH5 VPSA system employs a mass-flow sensor that automatically recalibrates the adsorption cycle based on atmospheric density, ensuring the 93% purity remains constant even as air thins.
What is the maintenance schedule?
Routine maintenance includes checking external air intake filters monthly and following the manufacturer's internal service intervals (typically every 5,000 operational hours) for the vacuum pump seals.
