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.
Features
• 100% 3A filter cartridge with powerful drying capacity, not mutual mobile, avoid the povder production.
• 100µm filter pad to keep an efficient filtration under minimum pressure drop. Corrosion resistant powder coating finish is applicable to various environments. Threaded connection and welded connection is normal design and customer design is available.Could be mounted in any desirable direction.
