Industrial RD-5-11188-0P Filter Dryer Receiver

The Red Dot RD-5-11188-0P is a high-capacity receiver-drier (filter-dryer) for automotive air conditioning, sized 3 inches in diameter by 10 inches long and also cataloged as 74R3328 in the Red Dot 74-series. This unit is designed for refrigerant circuits using R-12, R-22, and R134a, and it combines a desiccant-filled moisture absorber with a filtration element to remove moisture and particulates before the refrigerant enters the expansion device. By trapping water and debris, it helps protect components such as the compressor and other valve assemblies and supports refrigerant purity within the system.
