Combined Oxygen Generator

Our combined oxygen generator integrates a refrigerated dryer, a precision filtration system, an air buffer tank, an oxygen buffer tank, and a dual-tower oxygen generator into a single skid-mounted unit. Users simply need to connect the air inlet to an air compressor and the oxygen outlet to the oxygen application. This design greatly optimizes the user experience by eliminating the need for installation and commissioning, saving both space and time, while providing a more efficient and convenient gas supply solution.

Benefits
▔▔▔
 
Product Characteristic
▔▔▔
Built-in Dryer & Filters
The integrated air dryer and filtration system ensures that only clean, dry air enters the oxygen generator. This protects the molecular sieves from moisture and contaminants, prolongs equipment life.
Precision Pressure Sensor
High-quality SMC pressure sensors ensure precise pressure monitoring, with real-time data transmission to the PLC for enhanced process control.
 
 
Premium Absorbents
Custom-designed molecular sieves with optimized packing density, pore structure, and adsorption efficiency deliver higher oxygen output per unit volume while significantly extending service life.
 
Application
▔▔▔
Small Medical Facilities
Integrated oxygen generation with built-in air treatment supports clinics and private hospitals needing stable 90–95% oxygen without large floor space.
 
Laboratories & Research
Provides a stable, high-purity oxygen flow with precise control, ensuring reliable performance for laboratory experiments and analytical processes.
 
 
Light Industrial Use
Supplies a reliable oxygen source for oxidation reactions and small-scale material processing, specifically designed for applications where installation space is limited and compact system layout is required.
FAQ
▔▔▔
  • Why choose on-site oxygen generation instead of liquid or bottled oxygen?
    Created with Sketch.
    形状 Created with Sketch.
    On-site gas generation features lower investment and operating costs, a smaller footprint, easier management, and simpler maintenance compared to liquid or bottled oxygen supply.
  • How does the operating cost of on-site oxygen generation compare to liquid oxygen or bottled oxygen supply?
    Created with Sketch.
    形状 Created with Sketch.
    The operating cost of on-site oxygen generation is significantly lower than that of liquid or bottled oxygen supply due to the reduction of transportation, rental, storage fees.
  • Is on-site oxygen generation suitable for small businesses?
    Created with Sketch.
    形状 Created with Sketch.
    Yes, it is suitable for small businesses as it offers quick ROI, small business tend to gain more profit with on-site oxygen generators.
  • How does on-site gas equipment ensure gas purity and stability?
    Created with Sketch.
    形状 Created with Sketch.
    Every unit have passed factory tests to make sure they have meet the purity, flowrate, and other requirements. With routine maintenance, the unit will work very steady and reliable for continous oxygen production.
  • Why choose our combined oxygen generator?
    Created with Sketch.
    形状 Created with Sketch.
    Our combined oxygen generator integrates a refrigerated dryer, precision filtration system, air buffer tank, oxygen buffer tank, and dual-tower PSA oxygen generator into a single skid-mounted unit. Users only need to connect the air inlet to a compressor and the oxygen outlet to their application. This compact design eliminates the need for installation and commissioning, saving time and space while providing a convenient and efficient gas solution.
  • For combined unit with built-in air dryer, do you have to turn on the dryer manually?
    Created with Sketch.
    形状 Created with Sketch.
    No, you do not need to turn on the dryer manually. Dryers made by us comes with chain-command feature. So when you turn on the oxygen generator, the dryer turns on as well. Same when shutting down the unit.
  • Can a PSA oxygen generator operate continuously?
    Created with Sketch.
    形状 Created with Sketch.
    Yes, it can operate continuously 24/7.
  • How often does the adsorbent in an oxygen generator need to be replaced?
    Created with Sketch.
    形状 Created with Sketch.
    With proper maintenance, the molecular sieve typically lasts up to 5 years.
  • What is the typical maintenance cost for an oxygen generator?
    Created with Sketch.
    形状 Created with Sketch.
    It depends on the size and configuration of the unit.
  • Is maintenance difficult?
    Created with Sketch.
    形状 Created with Sketch.
    No, the maintenance is not difficult. We have both video instructions ready for the users and it is relatively easy which most of our clients can do the maintenance on their own.
  • How often should precision filter elements be replaced?
    Created with Sketch.
    形状 Created with Sketch.
    Every 5,000 hours of operation.
  • How often is maintenance?
    Created with Sketch.
    形状 Created with Sketch.
    The generator doesn’t require frequent maintenance. Detailed maintenance list and schedule can be requested at support@kstkmanufacturing.com
