Carbon Molecular Sieve takes the appearance of cylindrical black solid, contains countless 4 angstrom fine pores. It can be used to separate air into nitrogen and oxygen. In industry, CMS can concentrate nitrogen from air with PSA systems, up to 98%~99.999% N2 purity. Our CMS products have the character of large nitrogen yield capacity; high nitrogen recovery. It can meet the requirement of all types of PSA nitrogen systems. The carbon molecular sieve is widely applied in petroleum chemical industry, the heat treatment of metal, the electronic manufacture and food preservation industries.
