A properly sized coil is vital to HVAC system efficiency, and to fully-support residential or commercial HVAC needs Armstong offers a full line of cased and uncased Omniguard evaporator coils.

Omniguard coils feature advanced materials coupled to a proven tube and fin design providing advanced protection against volatile organic compounds -- like aerosols and paint emanations -- which can wreak havoc on an HVAC system in both indoor and outdoor environments.

Omniguard coils are also provided with Microban drain pans and MHT technology. The Microban drain pans provide antimicrobial protection against mold and mildew, eliminating a potential source of contamination to the air supply. Armstrong’s MHT technology is its featured rifled tubing, which enhances refrigerant flow, increases the available surface area and maximizes heat transfer efficiency. With removable cabinets, single drain pan and matched system components Armstrong Air keeps a system running at peak performance.
