13172 Robinair Filter - Pump Oil Maintenance Kit with 34724 Filter Designed for newer units manufactured after 03-1998.. This filter-drier has been specifically formulated using XH9 drier desiccant to trap acid and particulates and is formulated to remove water from the refrigerant. DO NOT accept look alike or knock off filters. You must change the filter-drier to assure adequate moisture and contaminant removal. Robinair’s "High Vacuum Pump Oil" is engineered to maintain maximum viscosity at high running temperatures and to improve cold weather starts. Laboratory tests prove that Robinair "High Vacuum Pump Oil" is more thermally stable in comparison to other leading brands, which means it resists breaking down due to heat for a longer period of time.

Robinair "High Vacuum Pump Oil" has a lower moisture content than other oils, thanks to our special packaging and handling procedures. Moisture degrades the oil’s purity, thinning it and reducing the pump’s ability to reach a deep vacuum.

Keep recovery and recycling units operating at peak efficiency with a convenient maintenance kit. Contains one quick change filter-drier to be used on both R-12 and R-134a stations, and one 16 ounce bottle of our Premium High Vacuum Pump Oil.
