Description

Technical Field

High-purity oxygen is used in oxygen supply therapy, operating rooms, intensive care units and other links. Therefore, the research and development and application of purification and filtration equipment are of great significance to medical diagnosis and treatment. In scientific research or laboratory fields, high-purity oxygen is often used in experiments and research to provide pure gas for experiments. In industrial production, high-purity oxygen is often used in welding, cutting and other production processes that require high-temperature gas.
