A nitrogen gas generator does not require a cylinder and is a device that generates (separates) nitrogen from the atmosphere around us. You can generate only the amount you need when you need it. Nitrogen gas is a colorless, tasteless, odorless, non-flammable gas that makes up about 78% of the air, and because it is scientifically stable, it is used for sealing and purging to improve safety and to maintain quality. It is widely used in the food industry, semiconductors, petrochemicals, research institutes, etc. to prevent oxidation and discoloration.
