Membrane air separation of nitrogen called hollow fiber membrane separation, It is made of air, which can separate oxygen and nitrogen under certain pressure by using different gases such as oxygen and nitrogen to have different infiltration rates in the membrane.
Compared with other nitrogen plant it is more simple structure, smaller volume, no switch valve, less maintenance, produce gas quickly (≤3 minutess), convenient of capacity, it is especially suitable for medium and small of the nitrogen purity to 99.5% or less nitrogen users, have an optimal function price.
When the purity of nitrogen is over 98%, the price is more than 15% higher than that of PSA nitrogen generator of the same specification.
