Emerson Alco 049175 Filter Drier

The Emerson Alco 049175 (Model ASD75S11W) is a high-capacity suction line filter drier designed for mission-critical contaminant control in commercial and residential HVACR systems. Built with a 75 cubic inch desiccant volume, this unit is engineered to protect the compressor from moisture, acid, and solid debris following a burnout or during a new system commissioning. It features 1 3/8" sweat (ODF) solid copper connections to ensure a leak-free braze and 40-micron filtration to trap fine particulate matter before it reaches the crankcase. With a 500 PSI max pressure rating, the ASD series is compatible with CFC, HCFC, and HFC refrigerants, including R-22, R-407C, and R-410A. The dual access valves allow for precise pressure drop monitoring across the core, ensuring the system operates within peak efficiency parameters. This premium drier utilizes a specifically blended desiccant to provide maximum acid neutralization, extending the operational life of the compressor in demanding environments.

• Enhanced Compressor Protection: 40-micron filtration traps carbon, metallic dust, and scale that can cause premature mechanical failure.
• Universal Refrigerant Compatibility: Specialized desiccant blend effectively manages moisture in both mineral and POE oil systems.
• Optimized Pressure Monitoring: Integrated dual Schrader valves facilitate easy differential pressure checks to determine core saturation.
• Durable Construction: Corrosion-resistant epoxy powder paint finish and solid copper fittings withstand harsh mechanical room environments.
• High Acid Capacity: Superior acid removal capabilities make this an essential component for system cleanup after a compressor burnout.

What is the maximum pressure drop allowed across the drier?
Technicians should monitor the differential pressure; typically, a drop exceeding 3 PSIG in a suction line indicates that the core is restricted and a replacement is necessary to prevent oil return issues.

Can this drier be used in both liquid and suction lines?
No, the ASD75S11W is specifically designed as a suction line drier with a high-flow, low-pressure-drop internal structure optimized for gas-phase filtration.

Is this unit compatible with high-pressure R-410A systems?
Yes, the 500 PSI (PSIG) maximum working pressure satisfies the requirements for R-410A suction side applications.
