30Nm³/h 93% Purity VPSA Oxygen Generator Industrial Oxygen Generator for Specialized Chemical Production
Product Description
The VPSA Oxygen System (Vacuum Pressure Swing Adsorption Oxygen Generator) is an industrial-grade oxygen supply equipment based on vacuum pressure swing adsorption technology. It selectively separates oxygen and nitrogen from air through high-efficiency lithium-based molecular sieves, featuring core advantages of stable flow rate, controllable purity, low energy consumption, and strong corrosion resistance.
As a mainstream model of Industrial Oxygen Generator, the 30Nm³/h flow rate and 93% purity accurately match the process needs of oxidation reactions, catalytic synthesis, and other operations in small and medium-sized chemical production. It requires no complex refrigeration system, with a startup time of only 20-30 minutes, and can adapt to the harsh working conditions of high temperature, high dust, and strong corrosion in chemical workshops, serving as a key equipment for chemical enterprises to achieve continuous production.

Specialized Installation and Anti-Corrosion Measures for Chemical Scenarios
The installation of VPSA Oxygen System in chemical workshops must focus on safety and corrosion resistance to avoid equipment failures or potential safety hazards caused by improper installation.
- Installation site: Select a well-ventilated area away from reaction kettles and flammable and explosive medium storage areas. The equipment foundation is cast with reinforced concrete, with a bearing capacity of not less than 2.0t/㎡, and treated with an anti-corrosion coating (epoxy zinc-rich paint).
- Pipeline connection: Oxygen transmission pipelines are made of 316L stainless steel, and flange sealing adopts PTFE gaskets to prevent oxygen leakage and pipeline corrosion. After installation, pressure testing (test pressure is 1.5 times the working pressure) and nitrogen purging shall be conducted to remove impurities and moisture in the pipelines and avoid contaminating molecular sieves.
- Electrical system: Comply with the Ex d IIB T4 explosion-proof standard, with a grounding resistance of ≤4Ω, to ensure safe operation in chemical explosion-proof workshops.
It is recommended that installation and commissioning be performed by a professional team certified by psa oxygen plant manufacturer. After commissioning, the equipment shall be linked with the chemical DCS system to realize automatic adjustment of flow rate and pressure.
Maintenance Key Points and Service Life Extension Strategies
The complexity of chemical working conditions places higher requirements on the maintenance of VPSA Oxygen System. Scientific maintenance can extend the equipment's service life to 8-10 years.
- Daily maintenance: Check equipment operating parameters (purity, pressure, flow rate) daily, clean the air intake filter weekly, and replace the filter element of the pretreatment system monthly to prevent dust and corrosive gases from entering the adsorption tower.
- Core component maintenance: The molecular sieve is a key component - test its adsorption performance every six months. If the purity decreases by more than 2%, conduct regeneration treatment or replacement (normal service life is 3-5 years). For fans and valves (moving parts), check lubricating oil levels and sealing status quarterly, conduct a comprehensive overhaul annually, and replace aging seals and bearings. Avoid overloading the equipment during operation, and strictly control the working pressure within the rated range of 0.6-0.8MPa.
In addition, establish equipment maintenance records to document maintenance time, content, and equipment status, with special personnel responsible for management. It is recommended to contact professional service providers of vpsa oxygen generator for annual in-depth maintenance, including adsorption tower air tightness testing, passivation treatment of pipeline inner walls, and control system calibration. This fundamentally avoids equipment failures and ensures the continuity of chemical production.
With its precise 30Nm³/h flow rate and stable 93% purity, the VPSA Oxygen System has become an ideal oxygen supply equipment for small and medium-sized chemical production. Its pressure swing adsorption oxygen plant technology can not only meet process requirements but also adapt to the harsh environment of chemical workshops. Combined with standardized installation and scientific maintenance, it can help chemical enterprises improve quality and efficiency, reduce costs and consumption, and achieve sustainable production.
