Overview

The Sunair ARD-1058 is an in-line A/C receiver drier and desiccant element kit engineered for heavy-duty mobile air conditioning. A steel housing shields the desiccant core, while quick-connect inlet and outlet fittings streamline installation and field service. The 63 mm diameter by 240 mm length package effectively removes moisture from the refrigerant circuit to reduce acid formation, corrosion, and component wear. Built to strict OE standards, the ARD-1058 delivers OEM-equivalent performance in demanding off-highway and commercial environments and is widely used in Caterpillar equipment.
