The nitrogen generator produced by Jinan Deyang is an advanced gas separation technology. It uses membranes imported from South Korea to separate air to produce high-purity nitrogen. The air enters the polymer membrane filter after being compressed and filtered by a compressor. Different solubility and diffusion coefficients lead to different relative permeation rates of different gases in the membrane. Under certain pressure conditions, oxygen and nitrogen are separated by utilizing different permeation rates of gases with different properties such as oxygen and nitrogen in the membrane.
