Emerson Alco 049485 Filter Drier

The Emerson Alco 049485, also known as the A4F-D filter drier cartridge, is a high-capacity 26 cubic inch internal filtration component engineered specifically for suction line applications. This replacement filter drier cartridge is the direct performance match for use in BTAS-4 suction line filter shells, providing critical protection against moisture, acid, and solid contaminants that can lead to compressor failure. Designed for the professional service technician, the A4F-D ensures high flow capacity with minimal pressure drop, maintaining system efficiency in both refrigeration and air conditioning circuits. Its construction is optimized for the rigorous demands of HVACR suction line service, particularly during system clean-up after a burnout or during routine preventative maintenance to capture debris before it reaches the compressor inlet.

Key Benefits:

• Compatible with BTAS-4 suction line filter shells for seamless field replacement.
• Provides 26 cubic inches of filtration media to effectively manage moisture and acid levels.
• Functions as a high-efficiency refrigerant filter drier to protect internal valve surfaces.
• Directly interchangeable with the model A4F-D, ensuring exact physical fit and performance.
• Optimized for low pressure drop to prevent performance degradation in the suction piping.

Common Questions:

Is the 049485 compatible with all BTAS series shells?
This specific cartridge is sized for BTAS-4 shells. While the BTAS series uses similar technology, you must match the cartridge volume and shell size (Model A4FD) to ensure proper sealing and flow.

Can this cartridge be used in liquid line applications?
The A4F-D is specifically designed as a suction line filter drier cartridge. Using suction-specific cores in liquid lines may result in suboptimal filtration or excessive pressure restriction.

What contaminants does the Alco 049485 remove?
It is designed to trap solid particles, sludge, and harmful acids often found in systems following a motor burnout or long-term moisture contamination.
