Sporlan 450256-001 Filter Drier

The Sporlan 450256-001 is a professional-grade LLD 307S 7/8" ODF filter drier engineered for high-performance liquid line protection in residential and commercial HVACR systems. This 30-cubic-inch sealed model serves as a direct drop-in replacement for legacy part numbers 033000-3079 and 060178. Utilizing a 100% molecular sieve desiccant, it provides industrial-strength moisture removal and acid neutralization to prevent expansion valve plugging and compressor damage. Designed with 7/8" ODF solder connections, this unit ensures a leakproof, high-strength bond within the refrigeration circuit. Its robust steel construction is rated for a maximum working pressure of 650 psi, making it fully compatible with modern R-410A systems as well as R-22, R-134a, and various HFC/HFO blends. As a Parker Sporlan Catch-All equivalent, it maintains critical system chemistry and optimizes flow capacity for units ranging from 2 to 10 tons.

• Universal Compatibility: Direct engineering replacement for 033000-3079 and 060178 specifications.
• High-Efficiency Desiccant: 30 cu. in. volume provides superior water and acid capacity to protect against system burnout.
• Standardized Connections: 7/8" ODF sweat fittings allow for rapid installation on standard copper liquid lines.
• Durable Shell: Corrosion-resistant painted steel housing rated for high-pressure HVAC refrigerant drier applications.
