ERP ERSUD109 Air Conditioner Filter Drier

Refrigerator & Air Conditioner Filter Drier Universal For: SUD109, D109

Safety first: Sealed-system and refrigerant work requires a qualified refrigeration technician with the correct refrigerant and equipment.

Protect a cooling system with this ERP replacement filter drier for refrigerator and air-conditioner applications. A saturated filter drier can allow moisture and debris through the system, causing poor cooling, ice at the expansion device, or compressor damage. This drier uses a non-directional connection and is rated to a maximum pressure of 500 PSI. Universal is the catalog label used when no specific compatible brand is confirmed; verify the connection sizes, refrigerant type, and appliance model before ordering.
