What types of filter driers are carried by Jackson Systems & Supply?
Filter driers on Jackson Systems & Supply are primarily liquid line filter driers, including sealed hermetic models, OEM replacements, and some core-style sealed designs. They are available in a range of sizes and fitting styles for air conditioning and refrigeration service, rather than as a one-size-fits-all solution.
What is the difference between sealed hermetic and core-style designs?
A sealed hermetic filter drier is a compact, factory-contained unit designed for direct replacement, while a core-style design uses an internal core arrangement intended for strong contaminant control in specific applications. The construction affects service approach, fit, and contaminant-holding capacity, so the replacement should match the original design and application rather than being selected by size alone.
What should I check when choosing a replacement?
The most important factors are line size, connection type, flow/application, and capacity. Filter driers differ in ODF and sweat fittings, connection diameters, and desiccant volume. The are sized sized for system demand and contaminant protection.
Why do desiccant volume and filtration matter?
Desiccant volume affects how much moisture and acid the drier can absorb before becoming saturated, while filtration details influence how effectively it captures particulates.
Match size and capacity when choosing
When choosing, start with the original OEM part number and verify the line connection size and application before ordering. Filter driers on Jackson Systems differ by fitting size, cubic-inch capacity, and construction type.
