Recently, a "news" about the explosion of the pneumatic lift chair caused heated discussion on the Internet. When a Miss Liu in Xiamen sat in a pneumatic lift chair, the chair suddenly exploded, and the stunned Miss Liu was rushed to the hospital for rescue. The doctor took out more than a dozen pieces of blood-stained iron rings and screws from her body. The scene was shocking. .

In fact, there have been too many explosion accidents of pneumatic lift chairs in recent years. According to the investigation results of the relevant state departments: the cause of such accidents is the pneumatic rod used in the chair lift. Some black-hearted manufacturers used inferior pneumatic rods to save costs, causing the chair to explode. At present, the lifting chairs on the market are generally divided into three types: oil pressure, mechanical and air pressure. There is a cylinder in the pneumatic lift chair. The piston pneumatic rod in the cylinder moves up and down to control the lift of the chair. Regular manufacturers are filled with nitrogen, the concentration is generally above 99%, and the pressure is about one or two atmospheres. If the nitrogen purity is not high, the cylinder container wall is not strong or the seal is not tightly sealed, the chair may explode.

Wright gas springs have always paid attention to the safety and quality of products, and the requirements for gas sources are more stringent. In the process of continuous technical upgrading, looking for a more perfect process. The old bottled gas source is eliminated. The purity of nitrogen will be reduced after multiple processes such as collection, filling, and transportation. Such a gas source will have potential safety hazards and fail to meet the process requirements. Wright gas spring adopts air separation equipment, and the separated nitrogen gas is directly input into the inner tube of the gas spring, which avoids the defects of impure gas source and so on, so that the safety of the gas source of each gas spring is perfect. Strictly follow the bifma standard to achieve more than 100,000 times, with the chair for life!
