Emerson Alco 048213 Filter Drier

The Emerson Alco EK-304S liquid line filter drier is a premium 30 cubic inch compressor protection solution designed for high-capacity HVACR systems. Engineered with a 1/2" ODF sweat connection and a 20-micron filtration rating, this unit effectively captures solid contaminants while prioritizing moisture and acid removal. Utilizing a buffered desiccant blend of activated alumina and molecular sieve, the EK-304S ensures maximum refrigerant drying efficiency even in demanding systems using POE oil or mineral oil. Rated for a 680 PSI maximum working pressure, it is compatible with high-pressure refrigerants including R-410A, R-134a, and R-404A. The beaded desiccant design minimizes pressure drop across the liquid line, preventing flash gas issues at the expansion valve. For technicians performing re-piping or compressor changeouts, this 048213 model provides the volume capacity necessary to stabilize system chemistry and prevent premature TXV failure caused by moisture-induced sludge or debris.

• High-Moisture Capacity: Optimized desiccant blend for superior refrigerant moisture removal and acid neutralization.
• Superior Filtration: 20-micron internal filtration prevents system contamination from reaching critical metering devices.
• Durable Construction: Rated for 680 PSI, making it suitable for modern high-pressure HFC and HCFC applications.
• ODF Connections: Precision 1/2" sweat copper fittings allow for clean, leak-free brazing into the liquid line.
• Flow Efficiency: Beaded desiccant structure ensures high flow rates with low pressure drop for system stability.

Common Questions

Is the EK-304S compatible with R-410A systems?
Yes, this unit is rated for 680 PSI, making it fully compatible with R410A liquid line applications and other high-pressure synthetic refrigerants.

Can I use this filter drier on a suction line?
No, the Emerson EK-304S is specifically designed for liquid line installation. Using it on the suction side will cause significant pressure drop and potential compressor damage.

Does the 1/2" S indicate a sweat or flare connection?
The "S" suffix identifies this as a 1/2 inch ODF sweat connection. For flare applications, the EK-304 counterpart would be required.
