York 029-21710-000 Filter Drier

The York 029-21710-000 Filter Drier is a critical liquid line component designed for high-capacity moisture removal and acid neutralization in residential and light commercial HVAC systems. Featuring 3/8" flare connections, this solid core filter drier ensures a leak-free interface and simplified field replacement without the need for brazing. It is engineered to protect the expansion valve and compressor from harmful contaminants, utilizing a specialized desiccant blend optimized for HFC and HCFC refrigerants, including R-410A and R-22. The low pressure drop design maintains system efficiency and prevents flash gas formation, ensuring peak evaporator performance. As an OEM York replacement part, the S1-029-21710-000 provides exact dimensional HVAC part compatibility for Johnson Controls and Unitary Products Group equipment, maintaining the original system engineering specifications for refrigerant moisture removal and debris filtration.

• High-Retention Filtration: The solid core construction captures solid contaminants down to 20 microns to prevent capillary tube and TXV clogging.
• Universal Application: Compatible with POE, PAG, and mineral oils, making it a versatile choice for various system architectures.
• Corrosion Resistance: Finished with a durable powder coating to withstand high-humidity environments and prevent external housing degradation.
• Bi-Directional Capability: Designed for robust performance in standard liquid line applications to ensure system stability.

Is the York 029-21710-000 compatible with R-410A systems?
Yes, the desiccant and shell pressure ratings are fully optimized for the high-pressure requirements of R-410A and modern POE lubricants.

Do I need specialized tools for installation?
Because this unit features 3/8" flare fittings, it can be installed using standard adjustable or torque wrenches, eliminating the need for torches and nitrogen purging during the swap.

When should this filter drier be replaced?
Replacement is recommended whenever the refrigerant circuit is opened for service or if a significant temperature drop is detected across the drier, indicating a restricted core.
