Sporlan 401449 C-305-S Filter Drier

The Sporlan 401449 C-305-S Filter Drier is an industry-standard liquid line filter drier engineered for high-performance HVACR contaminant control. Featuring a 30 cubic inch molded porous core, this unit utilizes a specialized blend of desiccants to deliver maximum moisture removal and acid adsorption in commercial and residential systems. Designed with 5/8 ODF solder connections, it ensures a leak-proof fit for high-pressure applications, including those using R-410A, R-22, and various HFC/HCFC refrigerants. The Sporlan Catch-All C-305-S protects sensitive components like thermostatic expansion valves (TEV) and compressors by capturing solid debris, sludge, and wax with minimal pressure drop. With a maximum rated pressure of 650 psig, this sealed model drier is a reliable choice for contractors performing field replacements or OEM installations where system 100% cleanliness is critical for long-term efficiency and capacity.

• Dual-Action Contaminant Removal: Effectively captures moisture, hydrofluoric acid, and organic acids to prevent system corrosion.
• Superior Filtration: The molded desiccant core filters out scale, solder particles, and carbon down to microscopic levels.
• Multi-Refrigerant Compatibility: Rated for use with R-134A, R-22, R-404A, R-407C, R-410A, and other common refrigerants.
• Robust Construction: Features a durable epoxy powder-coated shell and solid copper fittings for simplified brazing and corrosion resistance.
• High Flow Capacity: Optimized internal geometry ensures high ton ratings while maintaining a negligible pressure drop across the 30 cubic inch volume.

What is the difference between ODF and SAE connections for this drier?
The C-305-S features ODF solder (sweat) connections, which require brazing for a permanent, leak-proof seal. This is typically preferred for fixed installations compared to SAE flare fittings which are mechanical.

Can this filter drier be used on the suction line?
No, the Sporlan C-305-S is specifically designed for liquid line applications. Suction line driers require different flow characteristics and core compositions to handle oil return and lower pressure drops.

Is this unit compatible with POE and mineral oils?
Yes, the blended desiccant core is formulated to be compatible with all standard refrigerant oils, including POE, PVE, and mineral oils, effectively removing the products of oil decomposition like varnish and sludge.
