Air Compression & Pre-Treatment – Ambient air is compressed and purified by air dryers and filters.
PSA Adsorption Process – Nitrogen is adsorbed under pressure by zeolite molecular sieves, while oxygen passes through as the product gas.
Cyclic Operation – Two adsorption towers work alternately, ensuring continuous oxygen production.
Product Delivery – Oxygen is collected in a buffer tank and delivered to the application pipeline or filling station.
