Sporlan 401328 C-303 Filter Drier

The Sporlan 401328 C-303 Filter Drier is a 30 cubic inch sealed liquid line protector engineered for high-capacity contaminant removal in systems ranging from 3 to 6 tons. Featuring the industry-standard Catch-All molded porous core, this drier utilizes a specialized blend of desiccants to deliver high moisture and acid capacity, effectively neutralizing corrosive hydrofluoric and organic acids while preventing expansion valve freeze-ups. Designed with 3/8 SAE flare connections, the C-303 ensures a leak-proof seal and simplifies replacement in the field without the need for brazing. With a maximum rated pressure of 650 PSIG, it is fully compatible with modern HFC and HCFC refrigerants, including R-410A, R-22, R-404A, and R-134a. The rugged steel shell and fine outlet safety filter provide superior filtration of scale, sludge, and solder particles, ensuring refrigerant system reliability and long-term compressor protection even under heavy debris loads.

• Optimized Contaminant Filtration: The solid core design captures particles down to a microscopic level in a single pass to protect the TEV.
• Superior Acid Neutralization: Active desiccant granules adsorb harmful acids produced by oil breakdown or moisture entry.
• Durable Construction: Painted steel shell resists corrosion and is rated for high-pressure R-410A applications.
• Standard Fitting Compatibility: 3/8" SAE flare connections allow for quick mechanical installation on standard liquid lines.
• Large Desiccant Volume: 30 cubic inches of effective volume provides extended service life for larger residential and light commercial equipment.

• Is the Sporlan C-303 compatible with R-410A systems? Yes, it is UL listed for a maximum working pressure of 650 PSIG, making it suitable for modern high-pressure refrigerants.
• Can this filter drier be used for burnout cleanup? While the standard C-303 provides excellent acidification protection, the "HH" core version is typically preferred for severe burnout cases.
• What is the difference between the C-303 and C-303-S? The C-303 features 3/8" SAE flare connections, whereas the C-303-S utilizes 3/8" sweat ODF solder connections.
