Emerson Alco 048211 Filter Drier

As a core component for maintaining system dehydration and debris management, the Emerson Alco 048211 (Model EK303S) is a premium liquid line filter drier designed for high-pressure applications up to 680 PSI. This 30-cubic-inch unit features a 3/8" sweat (ODF) solid copper connection, ensuring a leak-resistant interface during high-temp brazing. The EK303S filter drier utilizes a compacted bead core composed of a high-capacity desiccant blend, optimized for maximum moisture removal and acid neutralization in systems using POE oils. With a 20-micron outlet pad, it provides superior filtration to protect expansion valves and compressors from particulate damage. Engineered for refrigerant compatibility with R-410A, R-22, R-134a, and other HFC/HCFC blends, this HVAC filter drier is the standard for contractors requiring a beaded core filter drier that maintains structural integrity under mechanical shock or pressure surges. Its corrosion-resistant epoxy finish and steel shell construction make it a reliable choice for demanding commercial or residential environments.

• Enhanced System Protection: The 20-micron filtration pad traps fine contaminants before they reach sensitive metering devices.
• Universal Application: Fully compatible with R-410A, R-22, R-134a, and R-404A refrigerants, simplifying truck stock.
• High Capacity Desiccant: The 30-cubic-inch compacted bead design offers superior acid and water stripping for long-term compressor safety.
• Durable Construction: Features solid copper connections for easy brazing and a shock-resistant steel shell.

Is the EK303S compatible with POE oils?
Yes, the desiccant blend in the EK303S is specifically approved for use with POE oils and is a recommended match for Copeland compressors.

What is the maximum working pressure for this drier?
This unit is rated for a maximum pressure of 680 PSIG, making it safe for high-pressure R-410A systems.

Can this filter drier be used for burnout cleanup?
The EK series is primarily a liquid line filter drier for moisture and acid protection. For major motor burnouts, a dedicated suction line burnout drier is typically recommended in conjunction with this unit.
