Lett Filter and Drier

• 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 100µm filter cartridge.

• Model DFS dry filter’s molecular sieve is %100 3A solid filter cartridge. The solid filter is used for HFC and HCFC refrigerants and synthesised polyester oil (POE or PAG) system.
