Emerson Alco 062255 Filter Drier

The Emerson Alco BFK-053S (062255) is a high-performance bi-flow liquid line filter drier engineered specifically for heat pump applications utilizing R-410A and other high-pressure refrigerants. This 5 cubic inch unit features a 3/8" ODF sweat connection and is rated for a maximum working pressure of 680 PSI. Utilizing a specialized blend of molecular sieve and activated alumina, the BFK-053S provides superior moisture acid removal while maintaining low pressure drop during reverse cycle operation. The internal check valves allow for bidirectional flow without the need for external piping, simplifying installation in tight cabinetry. With a 40-micron filtration rating and a durable powder coat finish, this drier ensures long-term system cleanliness and protects the expansion valve (TXV) from debris and contaminants. It is an essential component for technicians performing standard maintenance or compressor burn-out recovery on residential and light commercial heat pumps.

• Internal Check Valves: Eliminates the need for external check valves and additional brazing points during heat pump service.
• High Pressure Rating: Optimized for R-410A systems with a 680 PSI design pressure to prevent canister failure.
• Desiccant Blend: High-capacity activated alumina and molecular sieve provide maximum protection against acid buildup and moisture.
• Compact Profile: The 5 cubic inch size allows for easy fitment in compact condenser units where space is a premium.
• Shock Resistant: Solid core construction minimizes the risk of desiccant breakdown and downstream clogging.

Can the BFK-053S be used with POE lubricants?
Yes, the specific desiccant blend in this liquid line drier is designed to work effectively with Polyolester (POE) oils and is fully compatible with modern HFC and HFO refrigerants.

Is this unit suitable for horizontal or vertical installation?
The BFK-053S can be installed in any orientation; however, for optimal performance in heat pump applications, verify that the flow direction aligns with the bidirectional internal check valves.

Does this filter drier protect against system burnouts?
While primarily a moisture and acid removal tool, its high-capacity filtration helps capture carbon and metallic debris commonly found after a compressor failure, protecting the new components.
