Emerson Alco 047604 Filter Drier

The Emerson Alco 047604, professionally known as the EK-053S liquid line filter drier, is a high-performance solution for moisture and acid control in residential and commercial refrigeration systems. Designed with a 3/8" sweat ODF connection and a compact 5 cubic inch steel shell, this unit utilizes a premium compacted bead desiccant blend. This specific construction ensures maximum surface area contact for superior drying and acid titration, essential for protecting the compressor from premature failure. The 20-micron filtration outlet pad effectively captures debris, including solder particles and metal filings, before they can enter the expansion valve or capillary tube.

Rated for a maximum pressure of 680 PSI, this filter drier is fully compatible with R-410A, R-22, R-134a, and R-404A systems, as well as POE oils and mineral lubricants. The solid copper connections allow for easy brazing without the risk of oxidation common in plated fittings. For technicians managing high-pressure HFC and HCFC systems, the EK-053S offers the durability of a shock-resistant steel shell protected by a corrosion-resistant epoxy powder finish, ensuring reliable sequestration of system contaminants under extreme operating conditions.

Key Benefits

• Optimized Desiccant Blend: High-capacity water and acid removal prolongs system life and prevents component damage.
• Internal Filtration First: 20-micron rating ensures the desiccant remains effective by filtering particulates at the outlet.
• High Pressure Capability: 680 PSIG rating makes it suitable for modern high-pressure refrigerants like R-410A.
• Rugged Construction: Features a shock-resistant steel shell and corrosion-resistant powder coating for field longevity.
• Copper Connections: Solid copper ODF sweat ports facilitate faster, cleaner brazing for HVACR contractors.

Common Questions

Is the 047604 compatible with POE oil?
Yes, this model is approved for use with POE oils and is specifically recommended for Copeland brand products and other systems using synthetic lubricants.

Can the EK-053S be used on both R-22 and R-410A systems?
This filter drier is rated for 680 PSI, making it ideal for the higher operating pressures of R-410A, while remaining backward compatible with R-22 and other common refrigerants.

Does this filter drier use a loose bead or solid core desiccant?
The EK-053S features a premium compacted bead desiccant, which provides higher filtration efficiency and moisture removal capacity than many standard cores.
