LF818 Molecular Sieve 4A
1 Use
LF818 is used for deep drying of such gases as air, natural gas, rare gas, solvents, alkanes, refrigerator (R12, R22), as well as liquid; static drying of medicine packing, electronic components; or as dehydrator in paints, dyes and coating.
2 Regeneration
LF818 may be regenerated and reused by purging or vacuum at elevated temperature, the degree of regeneration is determined by regenerating temperature and regenerating humidity.
3 Technical parameters
Technical parameters of LF818 Molecular sieve 4A are seen in Table 1.
