Emerson Alco 053003 Filter Drier

The Emerson Alco 053003 (Model STAS-487T) is a heavy-duty liquid line filter drier designed for high-capacity commercial refrigeration and air conditioning systems. This take-apart shell features a 7/8" sweat (ODF) copper connection and a 48 cubic inch internal volume, optimized for CFC, HCFC, and HFC refrigerants, including R-410A, R-22, and R-404A. Built with a sturdy steel shell and a corrosion-resistant epoxy powder paint finish, it is rated for a 680 PSI maximum working pressure, making it a reliable choice for demanding environments where system integrity is non-negotiable.

Engineered for high-performance debris and moisture removal, the STAS-487T utilizes a single core (not included) and features a 100 mesh outlet screen to prevent desiccant migration. The slotted cover and unique internal hardware facilitate rapid core replacement with minimal downtime. This unit is a direct technical equivalent to the DHY0111. Whether used in liquid or suction line applications (with appropriate accessories), this replaceable core filter drier ensures a low pressure drop and long-term protection for your compressors and expansion valves.

• High-Pressure Rating: Rated for up to 680 PSI, suitable for modern high-pressure refrigerants like R-410A.
• Take-Apart Design: The STAS-487T shell allows for easy maintenance and core swaps without cutting the refrigerant lines.
• Full Flow Fittings: Designed with 7/8" ODF solid copper connections to ensure maximum flow and minimal pressure drop across the system.
• Durable Construction: Features a steel liquid line housing with epoxy powder coating to withstand harsh mechanical room conditions.
• Versatile Application: Compatible with a wide range of HVACR cores, including high-acid and moisture-removal blocks.

Is the filter core included with the STAS-487T?
No, this is a replaceable core filter drier shell only. You must purchase a 48 cubic inch core separately based on your specific filtration needs (e.g., moisture removal or system burnout cleanup).

Can this be used on the suction side?
Yes, the "T" model is frequently used as a suction line filter drier. For suction service, technicians typically install an access valve (X-11562-2) by removing the pipe plug to monitor pressure drop.

What is the difference between the STAS-487T and the DHY0111?
These parts are functionally identical and share the same 7/8" sweat connection and 48 cubic inch capacity, making the 053003 a direct drop-in replacement for DHY0111 installations.
