4 Ton Upflow R-410A TXV Cased Omniguard Evaporator Coil, 21" Width Furnace Cabinet, EAC4X49C-50

Armstrong Air EAC4X49C-50 – 4-Ton Omniguard® Cased Evaporator Coil

The Armstrong Air EAC4X49C-50 is a 4-ton cased evaporator coil designed for R-410A systems. Engineered for horizontal and vertical upflow configurations, this coil integrates Omniguard® Total Corrosion Protection technology to improve resistance against formicary and pitting corrosion, making it suitable for demanding HVAC environments.

This model features durable aluminum tube construction and copper refrigerant connections for efficient heat transfer and field reliability. With an airflow range of 1200 to 2000 CFM and factory-installed TXV, it is optimized for high-efficiency system performance.

Performance Features

• Omniguard® Coil Protection: Aluminum tube and fin design helps resist indoor corrosion from airborne contaminants
• Microban® Drain Pan Treatment: Integrated antimicrobial protection reduces microbial growth on drain surfaces
• Low-Retention Drain Pan: Mold-inhibiting design minimizes standing water and enhances indoor air quality
• TXV Included: Factory-mounted thermostatic expansion valve for R-410A provides precise refrigerant metering
• Interlocking Panels: Reduces cabinet air leakage, supporting total system efficiency
• UV Light Compatibility: Designed to be used safely with UV disinfection systems

Installation Notes

The EAC4X49C-50 is suited for installations where corrosion protection and service accessibility are priorities. This coil is intended for use with matched Armstrong Air condensers and air handlers in properly sized systems. Installation should be handled by certified HVAC personnel to ensure proper refrigerant handling, airflow alignment, and code compliance.

Contractor Considerations

This model’s all-aluminum construction and integrated Microban-treated drain pan reduce callbacks due to coil leaks and microbial growth. The inclusion of factory-installed TXV simplifies field setup, and the coil’s compact form factor allows for easy handling during retrofit and new system installations.
