A, From the Molecular sieve appearance to judge good or bad.
Generally look at the granularity size
Consistent size
Uniformly rounded and full
Color uniformity
If it is better, it means that the processing technology is good and the raw materials have less impurities.
B, From the Molecular sieve performance to judge good or bad
Generally look at the adsorption of nitrogen and oxygen, moisture, hardness.
The stronger the adsorption, the more oxygen produced
The better the moisture-proof performance, the longer the life of the machine
The higher the hardness, the lower the molecular sieve high temperature wear and tear, and the longer the machine life.
Below is CHEMXIN Oxygen Molecular Sieve technical data sheet
C, From the experimental test data to determine the good and bad.
Through the same model oxygen generator, test different molecular sieve oxygen production stability data comparison, the molecular sieve performance.
D, The good and bad of an oxygen concentrator is not all determined by the Molecular sieve.
1, The molecular sieve is an accessory in the oxygen concentrator, to determine whether the oxygen concentrator is good or bad, or to look at the whole, such as the overall life of the machine, the failure rate, molecular sieve filling technology, the quality of the four-way valve, the main board of components.
2, Each oxygen concentrator manufacturer not only only a molecular sieve supplier, today with A brand, tomorrow with B brand is very common.
3, Dealers can get buyers' after-sale and life-span feedback of the product after selling the product.
