Hydrogen guns are the key components of the hydrogen-filling machine and are used to connect hydrogen-filling machines to hydrogen-energy vehicles. The publication of the national logo supplements the performance requirements, test methods, markings, regulates the production and inspection of the products of hydrogen-filled guns in the country, and ensures that the specifications and quality of the products are consistent, and are important for the production of hydrogen-loaded guns and for the hydrogen-inflated industry.

Sunwise, dedicated to the national production of key components of hydrogen-filling machines, has developed high-pressure, high-reliability hydrogen-resistant guns to ensure the safety and simplicity of hydrogen-added operations and to reduce the cost of hydrogen-filled guns and to promote technological advances in hydrogen-filling equipment.
