Sporlan Controls 400503 Filter Drier

The Sporlan Controls 400503 Filter Drier, part of the industry-standard Catch-All Series, is a high-efficiency 3/8" ODF sweat sealed liquid line drier designed for critical contaminant control. This C-083-S model utilizes a 21 sq. in. surface filtering area and an 8 cubic inch molded porous core. The core consists of a specialized desiccant blend that provides maximum capacity for water and acid removal, preventing TEV failure and compressor motor burnout in systems ranging from 3/4 to 2-1/2 tons.

Built for the rigors of field service, the Sporlan 400503 features an epoxy powder coating for superior corrosion resistance and is UL listed for a maximum operating pressure of 650 psig. This makes it fully compatible with R-410A, R-22, R-134a, and R-407C refrigeration cycles. The solid copper ODF solder connections ensure leak-proof integration during brazing, while the internal assembly is spring-loaded to resist core breakage during handling or thermal cycling.

• Superior Acid Capture: The unique Catch-All core chemistry is unexcelled in removing hydrofluoric and organic acids formed during lubricant breakdown.
• Fine Particulate Filtration: Capable of trapping scale, sludge, and foreign matter down to 20 microns in a single pass with negligible pressure drop.
• Universal Refrigerant Compatibility: Engineered to perform with HCFC, HFC, and HFO refrigerants including R-404A, R-507, and R-410A.
• Industrial Durability: Steel shell construction with high-gloss polyester winter gray coating ensures integrity in residential and commercial environments.

Common Questions

Is the Sporlan 400503 compatible with POE and mineral oils?
Yes, the blended desiccant core is optimized for all commercially available lubricants, including high-moisture-affinity POE oils used in modern HFC systems.

Can this filter drier be used for burnout cleanup?
While the 400503 provides excellent acid removal in standard liquid lines, for severe compressor burnouts, technicians typically upsize to a larger Catch-All or use an "HH" core model specifically for wax and heavy acid removal.

What is the proper installation orientation for this drier?
This is a uni-directional (Uni-Flo) drier. Always verify the flow arrow on the label points toward the expansion device or evaporator to ensure the refrigerant passes through the safety filter and desiccant core correctly.
