The SEK filter driers adopt a composition design of drying and filtration and take gas as medium, effectively preventing filtration and soluble substances from entering the key positions of the refrigeration system, in order to secure an operation under the best condition. Features: 1. The automatic compressed device makes it possible to automatically fill in the worn molecules 2.Capable of dissolving pollutants such as moisture and acid 3. Motion of pads will not cause vibration 4. Filtration before drying 5. Corrosion resistant painting 6. Two kinds of connection methods: ODF and SAE 7. Maximum working pressure: 4.140Mpa The SAD filter driers Adopting the molding design and taking use of the drying agent with special mixture that provide excellent filtering effect, so as to prevent the refrigeration system from the pollution of noxious liquid and solid pollutants. Features: 1. High ability to remove pollutants such as moisture and acid 2. Adapting to refrigerants such as R12, R22,R134a, 404a, R502 3. Two kinds of connection methods:ODF or SAE 4. Very little pressure loss when full flow 5. Corrosion resistant painting 6. Maximum working pressure:4.140Mpa
