Armstrong Air 21" EAC1P30/36C-50 – Cased Evaporator Coil with Omniguard™ Protection

The Armstrong Air EAC1P30/36C-50 is a 2.5–3 ton cased evaporator coil built for high-performance air conditioning and heat pump systems utilizing R-410A refrigerant. This model is constructed with all-aluminum components and integrates Omniguard™ Total Corrosion Protection for extended service life in environments prone to moisture and airborne contaminants.

The coil features Armstrong Air’s proprietary MHT™ (Multi-Tube Heat Transfer) technology, designed to maximize heat transfer surface area and improve system efficiency. A fully insulated cabinet minimizes thermal loss and supports quieter operation. Its pre-formed duct flanges and rolled edges promote fast, clean installation in upflow or downflow configurations.

Key Features

• All-Aluminum Coil: Improves corrosion resistance and reduces potential for galvanic reaction in humid or coastal environments.
• Omniguard™ Coating: Factory-applied surface treatment enhances coil durability and heat transfer efficiency.
• MHT™ Technology: Enhances refrigerant distribution across the coil for consistent thermal performance.
• Antimicrobial Drain Pan: Mold- and bacteria-resistant polymer construction for improved indoor air quality.
• Preformed Cabinet Design: Rolled duct flanges and insulated enclosure simplify installation and reduce sound transmission.

Installation Considerations

The EAC1P30/36C-50 should be installed by an HVAC professional to ensure proper airflow alignment, line set compatibility, and charge balance with the outdoor unit. Factory-engineered features like duct flanges and cabinet insulation assist with field installation, but precise refrigerant and system commissioning are necessary for optimal function.
