Emerson Alco 048228 Filter Drier

The Emerson Alco 048228 Filter Drier, specifically the EK-757-S model, is a heavy-duty liquid line filter drier designed for high-capacity moisture and acid removal in commercial HVACR systems. Built with a 75 cubic inch compacted bead core, this unit utilizes a 75% molecular sieve and 25% activated alumina blend to ensure peak desiccant efficiency and system dehydration. Its "filtration first" architecture incorporates a 20-micron outlet pad, preventing particulate migration and protecting the compressor from internal debris. With 7/8" sweat ODF connections and solid copper fittings, it allows for reliable brazing into any compatible circuit. Rated for a 680 PSI max pressure, the EK757S is a high-performance HVAC filter drier compatible with R-410A, R-22, and other common CFC, HCFC, and HFC refrigerants, including POE oil applications. This Emerson EK757S is the industry standard for maintaining a clean, moisture-free liquid line in large-scale air conditioning and refrigeration installations.

• Universal Refrigerant Compatibility: Suitable for use with R-410A, R-22, R-134a, R-404A, and more.
• Superior Filtration: Features a premium 20-micron outlet pad for maximum particle retention.
• High-Pressure Durability: Solid steel shell construction rated for 680 PSIG working pressure.
• Advanced Desiccant Blend: Optimized for simultaneous high water capacity and acid removal.
• Ease of Installation: Solid copper 7/8 inch ODF connections ensure a secure, leak-free sweat joint.

Is the EK-757-S compatible with R-410A systems?
Yes, this model is UL-listed for a maximum working pressure of 680 psig, making it a reliable liquid line drier for high-pressure R-410A applications.

What type of desiccant is used in the Emerson 048228?
It uses a compacted bead core consisting of 75% molecular sieve for moisture and 25% activated alumina for acid neutralization, ideal for standard field replacements.

Can this filter drier be used for burnout cleanup?
The EK757S is designed as a standard liquid line drier. For severe system burnouts, a dedicated high-acid suction line filter drier is generally recommended for the cleanup phase.
