Sporlan 404281 HPC-165-S-HH Filter Drier

The Sporlan 404281 HPC-165-S-HH is a professional-grade reversible heat pump filter drier designed for high-capacity contaminant management in two-way flow systems. Engineered with a 5/8 ODF solder connection, this unit integrates seamlessly into liquid lines where heat pump cycles require filtration in both heating and cooling modes. Unlike standard driers, the HPC-165-S-HH features the specialized Sporlan HH core, which incorporates activated charcoal. This burnout filter drier is the industry standard for system clean-up, effectively adsorbing wax, resins, and organic acids that result from motor burnouts or oil decomposition.

The 16 cubic inch molded porous core utilizes a strategic blend of molecular sieve and activated alumina to ensure maximum moisture retention and acid neutralization. Internal metal check valves provide positive flow control, ensuring that captured debris remains trapped within the core regardless of the flow direction. With a maximum working pressure of 650 PSIG and a durable epoxy powder coating, this solid core filter drier is built to withstand the rigorous pressure fluctuations and environmental exposure common in residential and commercial heat pump service.

• Enhanced System Clean-up: The activated charcoal core is specifically formulated to remove oleoresins and varnish after a compressor failure.
• Superior Filtration: Captures solid contaminants including scale and solder particles down to microscopic levels with negligible pressure drop.
• Bi-Directional Efficiency: Proven metal check valves eliminate the need for external bypass piping, simplifying installation in reversible systems.
• Corrosion Resistance: The rugged steel shell features a high-grade powder coat finish to prevent rust in adverse field conditions.
• Universal Refrigerant Compatibility: Designed for use with all major HFC and HCFC refrigerants, including R-410A and R-22.

Is the HPC-165-S-HH a direct replacement for S1-404281?
Yes, the 404281 and the HPC-165-S-HH are technically identical components. These are frequently cross-referenced by OEMs like Source 1 (York/Johnson Controls) and are interchangeable in 5/8" liquid line applications.

When should I use an HH core versus a standard core?
The HH core should be selected for any system clean-up following a burnout or if you suspect high levels of wax and oil breakdown. For new installations or standard moisture protection, a standard HPC series core may be used, but the HH core provides the most comprehensive protection against chemical contaminants.

Can this drier be installed in any orientation?
While the internal check valves allow for reversible flow, it is recommended to install the drier in a vertical position with flow-up to ensure optimal desiccant contact and drainage during the off-cycle, though horizontal mounting is acceptable if necessary.
