Features:

1. Continuous and stable air supply: A continuous, stable-pressure compressed air supply is required to ensure the stable adsorption and desorption cycles of the molecular sieve.

2. High air quality requirements: The supplied compressed air must be strictly purified (oil-free, dry, and dust-free) to protect the carbon molecular sieve and extend its life.

3. Energy-saving and efficient: Variable frequency or high-efficiency airend designs are typically used to match the gas demand of the nitrogen generation system under different operating conditions, reducing energy consumption.

4. Interlocking control: Modern PSA nitrogen generation systems often feature intelligent interlocking control with the air compressor, automatically adjusting the compressor's output based on nitrogen demand.
