Sporlan 401376 C-304-HH Filter Drier

The Sporlan 401376 C-304-HH Filter Drier is an essential component for technicians managing low-temperature refrigeration systems where wax paraffin precipitation is a recurring issue. Engineered with the specialized HH charcoal style core, this 30 cubic inch capacity drier is specifically designed for wax removal and high-performance system cleanup following a hermetic motor burnout. Its 1/2" SAE flare connection ensures a secure, leak-proof mechanical fit in the liquid line, providing a massive surface area for capturing contaminants with negligible pressure drop.

For contractors servicing commercial refrigeration equipment, the C-304-HH provides superior moisture and acid removal, utilizing a molded porous core of blended desiccants and activated charcoal. This model is ideal for refrigerant cleanup in systems using HCFC, HFC, and HFO refrigerants, effectively adsorbing organic acids and sludge that cause expansion valve plugging. As a technician-grade liquid line filter drier, it ensures the integrity of the refrigerant charge by filtering out scale and solder particles down to microscopic levels in a single pass.

Key Benefits

• Optimized for Wax Removal: The HH core incorporates activated charcoal to sequester wax that typically precipitates in low-temp HVACR applications.
• High Acid Capacity: Exceptional at removing acid and products of oil decomposition, making it the industry standard for burnout cleanup.
• Reliable Filtration: The Sporlan Catch-All molded core technology prevents the release of desiccant fines into the system, protecting the compressor and TEV.
• Universal Compatibility: Rated for a maximum working pressure of 650 psi and compatible with all major refrigerant lubricants, including POE and mineral oil.

Common Questions

How does the HH core differ from a standard filter drier?
The "HH" designation indicates the inclusion of activated charcoal. While standard cores focus on moisture, the Sporlan C-304-HH is specifically formulated to handle wax, resins, and varnish that standard desiccants cannot effectively capture.

Is the C-304-HH suitable for use after a compressor burnout?
Yes, this is a primary burnout filter drier. Its ability to adsorb hydrofluoric and hydrochloric acids makes it critical for protecting a replacement compressor from residual acidic contaminants in the oil.

Can this drier be used with newer A2L or HFO refrigerants?
The Sporlan 401376 is rated for use with modern HCFC and HFC refrigerant blends, as well as several HFO options, provided the 1/2" flare connection and flow capacity match the system requirements.
