Emerson Alco 047618 Filter Drier

The Emerson Alco 047618, also known as the EK-165S, is a premium liquid line filter drier designed for high-capacity moisture and acid removal in commercial and residential systems. Built with a 16 cubic inch compacted bead core, this unit utilizes a specific blend of activated alumina and molecular sieve to maintain refrigerant stability and protect the compressor from burnout. For technicians performing a filter drier replacement, the EK-165S features 5/8" sweat (ODF) solid copper connections, ensuring a reliable braze joint and minimizing the risk of leaks under high-pressure conditions. With a 680 PSI maximum working pressure, it is fully compatible with R-410A, R-22, and other common HFC/HCFC refrigerants.

This HVAC filter drier stands out due to its "filtration first" design, which incorporates a 20-micron outlet pad. This prevents desiccant attrition and ensures that even the smallest contaminants are trapped before they can reach the expansion valve. Its corrosion-resistant epoxy powder paint finish and shock-resistant steel shell make it a standard choice for contractors looking for a 5/8" ODF filter drier that can withstand harsh environmental conditions while delivering a high nominal tonnage capacity, typically rated around 10.9 tons for liquid line applications.

• Enhanced System Protection: High moisture and acid removal capacity prevents the formation of ice and corrosive sludge.
• Universal Refrigerant Compatibility: Engineered for use with R-12, R-22, R-134a, R-404A, R-407C, R-410A, R-500, R-502, and R-507.
• Durable Construction: Shock-resistant steel shell and epoxy coating provide superior protection against physical damage and rust.
• Optimized Filtration: Internal 20-micron pad ensures maximum particulate capture without significant pressure drop.
• Ease of Installation: Solid copper sweat connections allow for straightforward brazing into existing liquid lines.

Is the EK-165S compatible with POE oils?
Yes, the EK series is approved for use with POE oils and is a recommended choice for Copeland brand products and other HFC systems.

Can I install this filter drier in either direction?
No, this is a uni-directional drier. You must follow the flow arrow on the label to ensure the spring-loaded desiccant bed and filtration media function correctly.

Does the 047618 replace older EK-165S models?
Yes, 047618 is the specific Emerson part number for the EK-165S model, and they are functionally identical for all 5/8" sweat liquid line applications.
