2 Ton Horizontal Piston Cased (Omniguard) Evaporator Coil, 17.5" Width Furnace Cabinet, EAC1P24B-50

Armstrong Air EAC1P24B-50 – 2 Ton Multi-Position Evaporator Coil with Omniguard® Protection

The Armstrong Air EAC1P24B-50 is a 2-ton uncased evaporator coil designed for use in multi-position installations. Engineered to pair with R-410A and R-22 systems, this coil enhances HVAC system efficiency while offering increased protection against corrosion and microbial growth. Its design supports reliable performance in residential and light commercial applications.

Engineered for Efficiency and Durability

This coil is built with aluminum construction for long-term resistance to environmental and chemical corrosion. It includes Armstrong Air’s Omniguard® coating on internal components, enhancing reliability in high-humidity or coastal installations. The factory-installed TXV (not included on all models) helps regulate refrigerant flow for improved performance across varying load conditions.

Product Highlights

• Omniguard® Coil Protection: Factory-applied coating helps guard against formicary corrosion, enhancing coil life and reducing service intervals.
• Microban®-Infused Drain Pan: Integrated antimicrobial protection helps reduce mold and bacterial buildup in the condensate area.
• Low-Retention Pan Design: Drainage system minimizes water accumulation and supports cleaner coil operation.
• Aluminum Coil with Copper Stubs: Aluminum tubing for corrosion resistance, with copper connections for simplified brazing.
• Interlocking Cabinet Panels: Helps minimize air leakage and streamline plenum integration.
