Model DFS Dry Filter
·Model DFS dry filter is used on the liquid piping of refrigeration and air conditioning unit to dry refrigerant (absorb water from system) and filter the solid from system in order to protect the refrigeration and air conditioning system for an efficient and safety operation.
·Model DFS dry filter is composed of 100% 3A molecular sieve and 100un filter cartridge.
·Model DFS dry filter’s molecular sieve is 100% 3A solid filter cartridge. This solid filter is used for HFC and HCFC refrigerants and synthesized polyester oil (POE or PAG) system.
