Sporlan 401309 C-304-S-HH Filter Drier

The Sporlan 401309 C-304-S-HH Filter Drier is a field-proven liquid line filter drier engineered for critical system cleanup and wax removal. Featuring a 30 cubic inch 80% molecular sieve and 20% activated alumina desiccant blend, this Catch-All series drier is specifically integrated with activated charcoal to neutralize harmful acids, resins, and varnish that standard cores often miss. The 1/2 ODF solder connection ensures a secure, leak-free braze for technicians working on systems up to 10 tons, making it a staple for low-temperature refrigeration and heavy-duty compressor burnout cleanup.

Built with a molded porous core, the C-304-S-HH provides superior refrigerant filtration of solid debris like scale and solder particles with negligible pressure drop. Its ability to adsorb moisture and organic acids simultaneously protects TXVs and internal compressor components from premature failure. This unit is compatible with most CFC, HCFC, and HFC refrigerants, including R-410A, and is rated for a maximum operating pressure of 650 psig.

Key Benefits

• HH Core Technology: Specifically formulated with activated charcoal to remove wax and products of oil decomposition in low-temp systems.
• High Acid Capacity: Exceptional ability to adsorb hydrochloric and hydrofluoric acids, preventing motor winding failure.
• 30 Cubic Inch Volume: Large desiccant surface area provides high water capacity for long-term system stability.
• 1/2 Inch ODF Connections: Solid copper fittings facilitate easy brazing into standard 1/2 inch liquid lines.
• System Reliability: Protects the expansion valve from clogging by capturing fine particles in a single pass.

Common Questions

When should I use an HH core instead of a standard core?
Use the HH style core when you are dealing with a compressor burnout or if you suspect wax buildup in low-temperature refrigeration systems. The charcoal content is specifically designed to scrub oil breakdown products that standard desiccants cannot capture.

Is the C-304-S-HH compatible with R-410A systems?
Yes, this filter drier is UL listed for refrigeration and air conditioning systems with a maximum rated pressure of 650 psig, making it suitable for high-pressure R-410A applications.

Can this be used on the suction line?
While primarily a liquid line drier, it is frequently utilized for temporary system cleanup. However, ensure the flow rate and pressure drop are within spec if used in a suction line application during a burnout recovery.
