In diverse industrial scenarios such as industrial processing, medical health care, aquaculture, laboratory scientific research, and food preservation, nitrogen and oxygen are two of the most widely used industrial gases. Traditional gas supply modes mostly adopt separate nitrogen generators and oxygen generators, which are plagued by high equipment investment costs, large floor space, high energy consumption and cumbersome operation and maintenance when multiple devices run simultaneously. They also suffer from mismatched gas supply parameters and poor equipment compatibility, greatly increasing enterprises’ production and operation costs. As an integrated multi-functional gas preparation device, the nitrogen and oxygen generator integrates dual functions of oxygen and nitrogen production. Adopting advanced pressure swing adsorption technology and taking air as the sole raw material, it can produce high-purity oxygen and nitrogen simultaneously or independently. With dual functions in one machine and intelligent and efficient performance, it perfectly solves many pain points of traditional separate equipment and has become a new optimal choice for gas supply in various industries.

　　In terms of structural design, the nitrogen and oxygen generator adopts a modular integrated architecture with a scientific and compact overall layout, completely eliminating the defects of large floor space and messy wiring of traditional separate equipment. The whole machine consists of six core modules: air pretreatment module, air compression module, gas separation core module, intelligent control module, pressure stabilization storage module, and purification and filtration module. All modules operate in coordination without mutual interference, ensuring excellent structural stability. The air pretreatment module filters dust, oil stains, water vapor and other impurities in the air to ensure clean gas sources from the source. The compression module provides stable pressure power for gas separation. The core separation module is equipped with special molecular sieves to complete precise screening of oxygen and nitrogen respectively. The intelligent control system coordinates the operation of the whole machine to realize accurate parameter regulation. The pressure stabilization and gas storage module ensures stable air pressure and uninterrupted gas supply. The multi-stage purification module further purifies gas to meet high-cleanliness gas supply requirements. The integrated structure greatly reduces equipment volume, requires no special large computer room, and features flexible installation and placement, suitable for various indoor and outdoor operation scenarios.

　　The core operating principle of the equipment relies on mature PSA pressure swing adsorption technology, which realizes efficient air separation by utilizing the differences in molecular size and adsorption rate of oxygen and nitrogen in the air. The whole process adopts physical gas production with no chemical pollution, no consumable loss and environmental protection. After the equipment is started, external air is purified and filtered by the pretreatment system to remove impurities, pressurized by the compression system, and then sent to the separation tower. Through the selective adsorption characteristics of special molecular sieves, oxygen and nitrogen components in the air can be accurately separated. The equipment supports independent dual-channel output, which can separately produce high-purity oxygen and nitrogen according to operational needs, or supply gas through both channels simultaneously, flexibly adapting to the needs of different working conditions. Adopting a cyclic alternating working mode, the equipment operates automatically throughout the process, supporting 24-hour uninterrupted and stable gas supply. It features fast start-stop, efficient response, and qualified gas can be produced immediately after startup without long preheating waiting time.

　　Compared with traditional separate gas generation equipment, the nitrogen and oxygen generator has prominent core advantages. In terms of cost, one machine replaces two sets of equipment, greatly reducing equipment procurement, installation and commissioning costs. Meanwhile, the energy consumption of a single unit is much lower than the superposed energy consumption of double units, which can greatly save electricity costs in long-term operation. In addition, the modular design of the whole machine reduces the failure rate, and only routine maintenance is required in the later stage, cutting operation and maintenance costs significantly. In terms of performance, the equipment has a wide adjustable range of gas purity, and the purity of oxygen and nitrogen can be accurately adjusted according to industrial needs to meet the gas supply standards of different scenarios. It delivers stable gas supply pressure and high gas cleanliness without impurities or peculiar smells, fully complying with industrial gas supply specifications. In terms of operation, the equipment is equipped with a fully automatic PLC intelligent control system with visualized touch screen operation, supporting one-key start-stop and unattended operation. It can real-time monitor core data such as gas purity, pressure, flow rate and equipment operating status, with automatic alarm and intelligent voltage stabilization in case of abnormalities, ensuring simple, safe and worry-free operation.

　　At the same time, the equipment optimizes detailed configurations for various operation scenarios with upgraded adaptability and safety. The fuselage is made of rust-proof and anti-corrosion materials, sturdy and durable with a long service life. It is equipped with a silent shock absorption structure with low operating noise, causing no environmental noise pollution. Multiple safety mechanisms including overpressure protection, overload protection, fault self-inspection and power-off protection are configured to effectively avoid equipment failures and potential safety hazards, ensuring stable and safe operation. Highly adaptable, the equipment is widely used in aquaculture oxygenation, medical and elderly care oxygen supply, nitrogen preservation for food fruits and vegetables, inert protection for laser processing, gas replacement in the chemical industry, gas supply for laboratory scientific research, precision electronic manufacturing and many other fields, fully meeting the oxygen and nitrogen gas needs of various industries.

　　As the production modes of various industries upgrade toward intelligence, integration and energy conservation, the drawbacks of separate gas supply equipment have become increasingly prominent, and integrated multi-functional gas generation equipment has become the mainstream of industrial development. With the core advantages of integrated structure, dual functions in one machine, energy saving and consumption reduction, intelligent convenience, safety and stability, the nitrogen and oxygen generator breaks the limitations of traditional gas supply modes, helps enterprises simplify equipment configuration, reduce operating costs and improve gas supply efficiency. It is a high-performance and cost-effective gas preparation equipment suitable for the development of various industries, assisting all sectors in realizing efficient, green and stable intelligent production and operation.
