Emerson Alco 048210 Filter Drier

The Emerson Alco 048210, specifically the EK-303 liquid line filter drier, is a high-capacity solution for moisture and acid removal in demanding refrigeration systems. Featuring a 3/8" flare connection and a 30 cubic inch desiccant core, this unit utilizes a 20-micron filtration pad to capture debris and desiccant fines before they reach the expansion valve. Optimized for HCFC and HFC refrigerants, it operates with a 680 PSI maximum pressure rating, making it suitable for modern high-pressure systems. The EK Series is engineered with a blend of activated alumina and molecular sieve to maintain low pressure drops while providing superior refrigerant filtration and system protection. This HVAC liquid line drier ensures long-term compressor reliability by neutralizing organic acids and capturing moisture that leads to oil breakdown and system sludge.

Key Benefits:

• Efficient Dehydration: High-grade molecular sieve beads maximize moisture removal from the liquid line.
• Internal Filtration: Specialized 20-micron filtration prevents orifice clogging and protects TXV operation.
• Robust Construction: Corrosion-resistant epoxy powder paint finish protects the steel shell in high-humidity environments.
• High Pressure Stability: Rated for a maximum working pressure of 680 PSI, ensuring compatibility with R-410A refrigeration systems.
• Flow Capacity: Designed for minimal pressure drop to maintain system efficiency and cooling capacity.

Common Questions:

Is the EK-303 compatible with POE oils?
Yes, the desiccant blend in the EK-303 filter drier is specifically designed to work with POE, PAG, and mineral oils without stripping additives.

What is the proper flow direction for this filter drier?
The Emerson Alco 048210 is a unidirectional drier. Ensure the arrow on the shell points toward the expansion device during installation.

Can this be used on the suction side?
No, this unit is a liquid line filter drier. For suction line protection after a compressor burnout, a dedicated suction line shell and core should be utilized.
