Oxygen generator is a kind of machine which produces oxygen. Its principle is to use air separation technology. Firstly, the air is compressed with high density, then the different condensation points of each component in the air are used to separate the gas and liquid at a certain temperature, and then further distillation is carried out.

Wuxi Zhongheng Gas Equipment Manufacturing Co., Ltd. is a specialized manufacturer of gas separation equipment. It has advanced technical advantages in the nitrogen machine industry. Because of its focus, it is professional. With advanced science and technology, high quality and efficient service, it enjoys a good reputation in the industry and high-tech entities in many fields. In line with the tenet of "scientific and technological innovation, pursuit of excellence, honest management", the company provides satisfactory products for the vast number of users.

Oxygen absorption method of oxygen generator:

Conversion Method of Oxygen Concentration in Oxygen Making Machine and Oxygen Making Machine Flow

Calculating formula: arrival alveolar oxygen concentration%=21+4 x oxygen generator flow (L/min)

Nursing points out that the oxygen content in the air is 21%. The oxygen concentration below 25% is similar to the oxygen content in the air. If the oxygen concentration is higher than 70%, the oxygen poisoning will occur if the duration exceeds 12 days. Therefore, patients with cardiopulmonary disease need to use a 3 liter or more flow oxygen generator.
