1. Q: What are the differences between different molecular sieve types?
3A is used to adsorb water in in all situations.
4A is usually used for adsorption of air compressor and desiccant
5A is Pressure Swing Adsorption which can be used for hydrogen drying.
13X is used to remove sulfur, water and carbon dioxide, and deep drying of gas
13X APG is a special molecular sieve for air separation, which can be used to remove sulfur and industrial oxygen production
13X HP is a special molecular sieve for medical oxygen production
Carbon molecular sieve is used for nitrogen generator
2.Q：What is the oxygen purity of 13X HP molecular sieve?
A：it depends on the equipment situation and the quantity of molecular sieve. If the air inflow and working pressure of the machine are normal and the oxygen production is 45m ³/ hour, the purity can reach 93% when using 1 ton 13X HP.
3.Q: How many years the molecular sieves can be used?
A: The molecular sieve can be used for 5-8 years under the normal equipment.
4 Q: How to regenerate molecular sieve?
