There is no unified definition of small PSA nitrogen generators in the industry, and different manufacturers and different application fields have different definitions. Generally speaking, it is defined by referring to the equipment flow rate, which generally refers to PSA nitrogen generators with a flow rate between 1Nm³/h and 5Nm³/h, which are mainly used in small nitrogen-using occasions such as laboratories, medical treatment, and food preservation.

Compared with traditional PSA nitrogen generators, small PSA nitrogen generators have distinct characteristics - smaller size, light and compact, portable, cheap, easy to operate and maintain, etc., but correspondingly, compared with large PSA nitrogen generators, its nitrogen flow rate will be lower, and the production efficiency may also be slightly different.

In general, the positioning of the two is not the same. It can be said that the emergence of small PSA nitrogen generators has filled some market gaps of traditional PSA nitrogen generators, such as:

1. Small size and light weight: small PSA nitrogen generators are small in size, light in weight, and easy to carry and install.

2. Low operating cost: The small PSA nitrogen generator adopts a modular design, which can be combined and disassembled according to needs, which is convenient for maintenance and replacement, and the operating cost is relatively low.

3. Easy to use: The operation of the small PSA nitrogen generator is relatively simple, without complicated operation procedures, and without the participation of professional technicians, a stable nitrogen supply can be achieved.

4. Quick start: The startup time of the small PSA nitrogen generator is shorter than that of the traditional nitrogen generator, and stable nitrogen output can be achieved within a few minutes.

5. Wide range of applications: The small PSA nitrogen generator is more suitable for use in laboratories, food processing, medical, electronics and other fields.

It is worth noting that small PSA nitrogen generators of different models, manufacturers and brands may differ in use and maintenance. Therefore, when choosing and using a small PSA nitrogen generator, you need to understand it clearly before purchasing and operating it.
