Emerson Alco 049481 Filter Cartridge

The Emerson Alco 049481 Filter Cartridge (Model A4F) is a critical component for technicians maintaining high-capacity commercial refrigeration systems. This suction line filter core provides exceptional 40-micron filtration across a substantial 189 square inch surface area, ensuring minimal pressure drop while effectively trapping solid contaminants, wax, and debris. Specifically engineered for BTAS-4 filter shells, this replaceable cartridge protects compressors from premature wear and ensures system longevity in both air conditioning and refrigeration applications. Its take-apart design allows for rapid element swaps during routine maintenance without specialized tools, making it the industry standard for suction line service. With a maximum operating pressure of 400 PSI and a 3.75-inch outer diameter, the A4F replacement cartridge offers precise fitment and professional-grade reliable performance for demanding HVACR environments.

• Optimized Compatibility: Designed exclusively as the direct replacement for BTAS-4 suction line filter shells (Model A4F).
• High Filtration Capacity: Features 189 square inches of filter media to capture particulates as small as 40 microns.
• Superior Compressor Protection: High-flow design prevents debris from entering the compressor, maintaining system efficiency.
• Industrial Build Quality: Robust construction supports high-pressure environments up to 400 PSI for reliable permanent or temporary service.

Common Questions

Does this cartridge include the necessary seals?
Yes, the 049481 cartridge typically includes the required O-ring for the BTAS-4 shell, though it is recommended to inspect all gaskets during the core changeout.

Can I use this for liquid line applications?
The A4-F model is specifically optimized for suction line service. For liquid line drying and moisture removal, a dedicated desiccant core like the A4-F-D should be utilized instead.

How often should the A4F filter be replaced?
Replacement intervals depend on system contamination levels; however, technicians should monitor the pressure drop across the BTAS-4 shell and replace the cartridge if values exceed manufacturer specifications.
