Filter drier for Heat Pump Castel DF316 / 5S 5/8" soldered

Two-way filter by CASTEL DB 316/5S (international designation 165S)

The Bi-Flow DB3 series filter is specifically designed for installation in liquid refrigerant lines in heat pumps and reverse cycle systems. The design, based on a 100% molecular sieve, ensures maximum moisture removal and is compatible with refrigerants such as HCFC, HFC, HFO, and HC. The two-way drainage filter by CASTEL is carefully designed to allow the flow of liquid refrigerant from the outer side of the filter core to the inside, regardless of the flow direction. This innovative solution effectively captures all impurities, making it particularly useful in heat pump systems where the purity of the refrigerant is crucial for efficient system operation.
