13A Activated Molecular Sieve-Spherical & Bar shape
Introduction & Specs
| Introduction | 13A molecular sieve is a new type of X-type molecular sieve, specifically designed for oxygen production. The oxygen production principle is as follows: A compressor uses pressure swing adsorption to draw air into the 13A molecular sieve, which absorbs waste gases such as nitrogen and carbon dioxide. Only oxygen remains, entering the gas collection tank. This oxygen is then purified by a high-pressure valve, raising the concentration to the required standard before being output by the oxygen concentrator.
|
| Benefits | l It features a high nitrogen adsorption capacity
l Excellent nitrogen-oxygen separation factor l Higher oxygen purity l Fast adsorption rate l Longer service life l Widely used in household and medical oxygen production systems
|
| Applications | l Used in cryogenic air separation devices to remove moisture and carbon dioxide from the air to assist in the cryogenic production of oxygen
