The HONGSEN DFS Filter Drier is designed to remove moisture and filter solid contaminants from refrigeration and air conditioning systems. It helps protect critical HVACR components from moisture-related issues and contamination, supporting efficient and reliable system operation.
The DFS dry filter uses a 100% 3A molecular sieve solid filter cartridge with a 100 μm filter element. It is suitable for systems using HCFC and HFC refrigerants along with POE or PAG synthetic oils.
Key Features
- Effective Moisture Removal: 3A molecular sieve helps absorb water and moisture from the refrigeration system.
- Solid Contaminant Filtration: The 100 μm filter element helps remove solid particles from the refrigerant circuit.
- 3A Molecular Sieve Cartridge: Uses a 100% 3A molecular sieve solid filter cartridge for effective drying.
- Wide Refrigerant Compatibility: Suitable for systems using HCFC and HFC refrigerants.
- POE & PAG Oil Compatible: Designed for refrigeration systems using synthetic POE or PAG oils.
- System Protection: Helps protect refrigeration and air conditioning components from moisture and contaminants.
- Wide Temperature Range: Suitable for medium temperatures from -40°C to +120°C.
