Lightweight Ambulance Breathing Oxygen Cylinders made from Aluminum Alloy Al6061 for home oxygen therapy, emergency medical services (EMS), pre-hospital care, and hospitals, nursing homes, clinic supply, and medical institutions.
Our Aluminum alloy gas cylinders can be refilled with rare, high-purity, calibration, and special gases. They are made of superior quality aluminum alloy and manufactured through procedures such as punching, drawing, heat treatment, CNC flow forming spinning, and anodic oxidation treatment to the inner surface. These cylinders are used for filling and refilling with various kinds of gases, such as rare gases, high purity gases, standard gases, and special gases. Their applications span across the chemical industry, electronic industry, medical treatment, gas, and coal mining fields, making them an ideal substitute for steel cylinders. We also have the ability to design and produce seamless aluminum alloy cylinders with special specifications and technical requirements.
