Castel DB308/4S Bi-Flow Filter-Drying Unit – 1/2" ODS / 5/8" ODM
The Castel DB308/4S is a hermetic Bi-Flow filter drier with a solid-state core for refrigeration, air-conditioning and heat pump applications with alternating flow direction. Thanks to its bi-flow design, it is particularly suitable for use in reversible air-conditioning systems and heat pumps, where the direction of refrigerant flow changes between heating and cooling modes.
The filter drier is installed in the liquid line and helps to protect the refrigeration circuit from moisture and contaminants. With a maximum permissible operating pressure of 50 bar and a wide operating temperature range, the DB308/4S is suitable for numerous modern and traditional refrigerants.
