Marvair 70370 Filter Drier

The Marvair 70370 Filter Drier is a refrigerant component used to remove moisture, acids and solid contaminants from sealed cooling circuits during operation in HVAC systems. It is installed in the liquid refrigerant line between the condenser and metering part, where it maintain clean refrigerant flow and protects internal components from contamination-related damage. It supports efficient system performance by reducing the corrosion, blockage, and compressor caused by moisture and debris accumulation. It is commonly used in commercial and residential air conditioning equipment, refrigeration units, and packaged cooling systems requiring controlled refrigerant conditioning and circuit protection.
